A dishwasher is designed to clean dishes, glasses, cookware, and utensils every day, but the appliance itself also needs regular cleaning. Food particles, grease, detergent residue, hard-water minerals, and moisture can gradually build up inside the machine. If these deposits are ignored, they can affect cleaning performance, create unpleasant odours, block filters, interfere with water circulation, and eventually contribute to mechanical problems.
Knowing how to clean a dishwasher safely is important because not every cleaning method is suitable for every appliance. Some household cleaning products can damage internal components, while excessive use of acidic products may affect seals, metal parts, or other materials over time. Bleach can also be unsuitable for certain dishwasher interiors, particularly stainless-steel tubs.
The safest approach is to combine regular manual cleaning with manufacturer-approved dishwasher cleaning products or methods specifically recommended for your appliance. This includes cleaning the filter, removing food debris, wiping the door seal, checking the spray arms, cleaning the drain area, and occasionally running an empty maintenance cycle.
This complete guide explains safe ways to clean a dishwasher, which products to use, which products to avoid, how often different parts should be cleaned, and how to deal with grease, limescale, odours, mould, residue, and food buildup.
The advice in this article is designed to be broadly relevant for dishwasher owners in the UK, USA, and Canada. However, dishwasher designs, water conditions, electrical systems, detergents, and manufacturer instructions can vary. Always check your appliance manual before removing components or using a cleaning product.
Why Does a Dishwasher Need Cleaning?
Many people assume that because a dishwasher uses hot water and detergent, it automatically cleans itself during every wash cycle.
Unfortunately, this is not completely true.
A dishwasher repeatedly receives dirty dishes containing:
- Food particles
- Grease
- Oils
- Proteins
- Starches
- Sauce residue
- Mineral deposits
- Detergent chemicals
Most of this material is washed away during normal operation. However, some debris can remain inside the appliance.
Over time, buildup may occur in:
- The filter
- Spray arms
- Door seals
- The bottom of the tub
- Drain areas
- Corners and gaps
- Detergent dispensers
Hard-water minerals may also accumulate on internal surfaces.
Regular cleaning helps prevent these deposits from becoming severe.
What Happens If You Never Clean Your Dishwasher?
A dishwasher that receives no maintenance may eventually develop several problems.
These can include:
- Bad smells
- Food particles on dishes
- Reduced cleaning performance
- Slow drainage
- Filter blockages
- Greasy residue
- Limescale
- Mineral deposits
- Spray arm blockages
- Mould or mildew
- Standing water
The exact problem depends on the appliance and how frequently it is used.
In many cases, a dishwasher does not suddenly stop working because it is dirty. Instead, problems develop gradually.
For example, a small amount of food trapped in the filter may not immediately affect performance. However, months of accumulated food debris can eventually restrict water flow and contribute to unpleasant odours.
Regular cleaning prevents small problems from becoming larger maintenance issues.
What Is the Safest Way to Clean a Dishwasher?
The safest general method involves several steps.
- Empty the dishwasher.
- Turn the appliance off if components need to be removed.
- Remove food debris.
- Clean the filter according to the appliance instructions.
- Wipe the interior.
- Clean the door seal.
- Inspect the spray arms.
- Clean the drain area.
- Use an approved dishwasher cleaner or recommended maintenance method.
- Run an appropriate cleaning cycle.
- Allow the interior to dry.
The most important rule is simple:
Always use a cleaning method suitable for your specific dishwasher.
A cleaning method that is safe for one appliance may not be recommended for another.
Start by Checking Your Dishwasher Manual
Before deep cleaning your dishwasher, check the manufacturer’s instructions.
This is especially important when dealing with:
- Removable filters
- Spray arms
- Drain pumps
- Self-clean cycles
- Stainless-steel interiors
- Water softeners
- Dishwasher salt compartments
Your appliance manual can tell you:
- Which components can be removed
- Which cleaning products are safe
- Whether vinegar is recommended
- Whether bleach should be avoided
- How to run a cleaning cycle
- How to access the filter
Never force a component that does not easily come out.
Dishwasher filters and spray arms have different locking systems depending on the model.
Safe Dishwasher Cleaning Method: Step-by-Step
Step 1: Empty the Dishwasher Completely
Remove:
- Plates
- Bowls
- Cups
- Glasses
- Pots
- Pans
- Cutlery
Cleaning an empty dishwasher allows you to inspect the entire interior.
It also prevents cleaning products from coming into contact with dishes unnecessarily.
Step 2: Remove Loose Food Debris
Inspect the bottom of the dishwasher.
Look for:
- Food
- Rice
- Pasta
- Seeds
- Paper
- Labels
- Small bones
- Broken glass
Remove loose debris carefully.
Wear gloves if necessary.
Sharp objects can occasionally become trapped near the filter or drain area.
Never reach blindly into a drain area if broken glass may be present.
Step 3: Clean the Dishwasher Filter Safely
The filter is one of the most important parts to maintain.
It collects food particles and debris removed from dishes during the wash cycle.
If neglected, the filter may contribute to:
- Bad smells
- Poor drainage
- Food particles on dishes
- Reduced cleaning performance
The exact cleaning process depends on the dishwasher model.
Generally, the process involves:
- Removing the lower rack.
- Locating the filter.
- Unlocking or twisting the filter.
- Lifting it out carefully.
- Removing trapped debris.
- Rinsing under running water.
- Using a soft brush if necessary.
- Reinstalling it correctly.
Do not use excessive force.
Do not use sharp objects to clean fine mesh.
Do not reinstall the filter incorrectly.
An incorrectly fitted filter may affect washing and drainage performance.
How Often Should You Clean the Dishwasher Filter?
The ideal schedule depends on dishwasher use.
Light Use
Inspect the filter every few weeks.
Normal Household Use
Check and clean it approximately once a month.
Heavy Daily Use
Inspect the filter more frequently.
Large households may need to clean filters more often than single-person households.
If you regularly wash heavily soiled cookware, check the filter more frequently.
Step 4: Wipe the Dishwasher Interior
Once the filter has been inspected, wipe the inside of the dishwasher.
Use:
- A soft cloth
- A non-abrasive sponge
- Warm water
Pay attention to:
- Interior walls
- Door edges
- Bottom of the tub
- Corners
- The front lower section
Food residue can collect in areas that are not directly reached by spray water.
Avoid using steel wool or harsh scouring pads.
These can scratch internal surfaces.
Step 5: Clean the Dishwasher Door Seal
The rubber seal around the door is another area that requires attention.
Moisture and small food particles can accumulate around the gasket.
Use a soft damp cloth to wipe:
- The rubber seal
- Door edges
- Corners
- Areas around the hinges
Do not use excessive force.
Avoid pulling or stretching the rubber gasket.
A damaged door seal can contribute to leaks.
Step 6: Clean the Spray Arms
Dishwasher spray arms distribute water throughout the appliance.
Small particles and mineral deposits can sometimes block the spray holes.
Blocked spray arms can result in:
- Poor cleaning
- Dirty dishes
- Reduced water circulation
If your appliance allows the spray arms to be removed safely, follow the manual instructions.
Inspect the holes.
Remove visible debris gently.
Rinse with water.
Do not force sharp objects into spray holes unless the manufacturer specifically recommends a particular cleaning method.
For some dishwasher designs, spray arms should not be manually rotated or pulled.
Step 7: Inspect the Drain Area
The drain area is located near the bottom of the dishwasher.
Food particles can collect here.
Check for:
- Debris
- Food
- Packaging
- Foreign objects
Remove loose material carefully.
Do not dismantle pumps or electrical components unless the manufacturer instructions clearly explain how to do so.
Some dishwasher pumps are not intended for homeowner servicing.
Step 8: Run a Dishwasher Cleaning Cycle
Many modern dishwashers have special programmes such as:
- Machine Care
- Self Clean
- Maintenance Cycle
- Tub Clean
If your dishwasher has one of these programmes, use it according to the manual.
These cycles are specifically designed to clean the appliance interior.
They may use:
- Higher temperatures
- Extended washing
- Special water circulation patterns
A dedicated cleaning cycle is often one of the safest options because it is designed for the appliance.
Using a Dishwasher Cleaner Safely
Dishwasher cleaning products are designed specifically for cleaning the appliance.
They can help remove:
- Grease
- Mineral deposits
- Soap residue
- Odours
Always follow the product instructions.
Do not use more product than recommended.
Using excessive amounts does not necessarily improve cleaning.
It may leave unnecessary chemical residue.
For regular maintenance, a dishwasher cleaner specifically formulated for appliance interiors can be safer than experimenting with strong household chemicals.
Can You Clean a Dishwasher With Vinegar?
White vinegar is commonly used as a household cleaning product.
It may help with:
- Mild odours
- Mineral deposits
- White residue
- Light buildup
However, vinegar should be used carefully.
Vinegar is acidic.
Excessive or frequent use may potentially damage certain dishwasher components over time.
For this reason, vinegar should not automatically be used every week or every month without checking the appliance instructions.
If your manufacturer permits vinegar cleaning, a commonly recommended method is:
- Empty the dishwasher.
- Place white vinegar in a dishwasher-safe container.
- Position the container securely in the dishwasher.
- Run an appropriate cycle without detergent.
Do not simply pour vinegar directly into parts of the dishwasher unless the appliance instructions specifically allow it.
How Often Should You Use Vinegar in a Dishwasher?
Do not assume that more vinegar means better cleaning.
Occasional use may be appropriate for some appliances.
Frequent use may expose internal materials to unnecessary acidity.
For regular maintenance, consider:
- A manufacturer-approved cleaner
- The dishwasher’s maintenance cycle
- Manual cleaning
Use vinegar only when appropriate for your appliance.
Can You Use Baking Soda to Clean a Dishwasher?
Baking soda can help neutralise unpleasant odours.
It may also assist with light surface cleaning.
Some homeowners use baking soda after completing another cleaning cycle.
However, baking soda is not a replacement for:
- Cleaning the filter
- Removing food debris
- Cleaning spray arms
- Maintaining the drain
Never assume that adding baking soda alone will solve a severe dishwasher problem.
If there is standing water, a blocked filter, or mechanical failure, the cause must be investigated.
Should You Mix Vinegar and Baking Soda in the Dishwasher?
No.
Avoid mixing cleaning products unnecessarily.
Vinegar and baking soda should not be combined together in the same cleaning process as though the reaction itself will provide better cleaning.
When combined, they react and largely neutralise one another.
If both are used as part of an appliance cleaning routine, they should be used separately and only where appropriate for the dishwasher.
Never mix cleaning chemicals without understanding the possible reaction.
Can You Use Bleach to Clean a Dishwasher?
Bleach should be used with extreme caution.
It is not suitable for every dishwasher.
Bleach may damage or discolour stainless-steel interiors and other components.
Never assume bleach is safe simply because it is commonly used for household cleaning.
Before using bleach:
- Check your appliance instructions.
- Check the material of the dishwasher interior.
- Check whether the manufacturer specifically permits bleach.
Never mix bleach with other cleaning chemicals.
Bleach should never be mixed with:
- Vinegar
- Acidic cleaners
- Ammonia
- Other unknown cleaning products
Dangerous chemical reactions can occur.
For most routine dishwasher maintenance, bleach is unnecessary.
Can You Use Dish Soap to Clean the Inside of a Dishwasher?
Regular hand-washing liquid should generally not be used inside a dishwasher wash cycle.
Dish soap produces excessive foam.
This can cause:
- Suds
- Leaks
- Overflow problems
- Excessive foam inside the appliance
Do not fill the detergent dispenser with hand dishwashing liquid.
If you are wiping the dishwasher manually, follow the manufacturer’s guidance regarding suitable cleaning products.
Can You Use All-Purpose Cleaner in a Dishwasher?
Not every all-purpose cleaner is suitable.
Some products may contain:
- Strong fragrances
- Bleach
- Abrasives
- Chemicals unsuitable for food-contact appliances
Use products specifically recommended for dishwasher interiors.
If using a cleaning product for external surfaces, keep it away from detergent compartments and food-contact areas unless the product instructions specifically permit such use.
Safe Way to Remove Grease From a Dishwasher
Grease can accumulate inside dishwashers.
Common areas include:
- Filters
- Door edges
- Interior walls
- The bottom of the tub
Start with manual cleaning.
Use warm water and a soft cloth.
Remove the filter and clean it according to the manufacturer instructions.
For heavier grease buildup, use a dishwasher cleaner designed for appliance interiors.
Avoid aggressive scrubbing.
Avoid metal brushes.
Avoid strong solvents unless approved.
Safe Way to Remove Limescale From a Dishwasher
Limescale is particularly common in hard-water areas.
Hard water contains minerals that can leave deposits on:
- Interior surfaces
- Spray arms
- Heating components
- Dishes
Signs include:
- White residue
- Cloudy glasses
- Chalky deposits
- Rough surfaces
The safest method depends on the dishwasher.
Possible options include:

These systems may require dishwasher salt.
Dishwasher salt is not the same as:
- Table salt
- Cooking salt
- Sea salt
Use the correct product designed for dishwashers.
Adding the wrong type of salt can potentially damage the appliance.
Dishwasher salt should not be used as a general cleaning product.
Its purpose is to support the appliance’s water softening system.
Safe Way to Remove Bad Dishwasher Smells
Bad smells usually have a cause.
Common causes include:
- Food trapped in the filter
- Grease
- Standing water
- Drainage problems
- Food debris in the tub
- Dirty door seals
Start by locating the source.
Follow these steps:
- Empty the dishwasher.
- Inspect the filter.
- Remove food debris.
- Clean the filter.
- Wipe the door seal.
- Inspect the drain.
- Clean the interior.
- Run an approved maintenance cycle.
Do not simply add air freshener or fragrance.
Masking the smell does not remove the underlying cause.
Safe Way to Clean Mould or Mildew in a Dishwasher
Mould or mildew may develop in damp areas.
Possible locations include:
- Door seals
- Interior corners
- Filter areas
First, remove the cause of persistent moisture and food buildup.
Clean the affected surfaces according to the appliance instructions.
If mould is extensive or repeatedly returns, investigate:
- Drainage problems
- Water leaks
- Seal damage
- Ventilation issues
Avoid mixing cleaning chemicals.
Never combine bleach with vinegar or acidic products.
