Check Manufacturer Guidelines: Some tumblers are dishwasher-safe; refer to the manufacturer's guidelines.

Avoid Harsh Detergents: If dishwasher-safe, use mild detergents to preserve colors and materials.

Top Rack Preferred: Place tumblers on the top rack to reduce exposure to intense water pressure and heat.

Regular Inspection: Periodically check for any signs of wear or damage after dishwasher use.
