Quick Answer

To keep your Squishmallows Sticker Bomb Tumbler looking great, hand-wash it with mild soap and warm water, avoid the dishwasher, and clean the straw regularly with a brush.

Why Hand Washing Is the Safest Choice

The Squishmallows Sticker Bomb Tumbler features a custom sticker pack that lets you personalize the surface. While the tumbler itself is designed for everyday use, the stickers are not meant to withstand the heat and agitation of a dishwasher. Hand washing with mild soap and warm water protects both the finish and the stickers, so your tumbler keeps its personality for longer.

The 30oz and 40oz sizes are built for daily hydration, which means they see a lot of use. Regular cleaning prevents residue buildup and keeps your drink tasting fresh, but the method matters. Avoid abrasive scrubbers that could scratch the surface or lift sticker edges.

Straw Maintenance Matters More Than You Think

The included straw is the part that touches your drink most, so it needs attention. If you don't clean it properly, mold and bacteria can develop inside the straw, especially if you use the tumbler for smoothies or other thick drinks. A simple rinse isn't enough—you need to scrub the inside regularly.

Most tumbler straws are dishwasher safe on the top rack, but hand washing with a straw brush is gentler and ensures every crevice is cleaned. If your straw is removable, take it apart from the lid to clean all the pieces thoroughly.

Step-by-Step Cleaning Routine

  1. Rinse immediately after use: Empty the tumbler and rinse it with warm water right after finishing your drink. This prevents stains and odors from setting in. Don't let the tumbler sit with leftover liquid for hours—it makes cleaning harder.
  2. Hand wash with mild soap: Fill the tumbler with warm water and a drop of mild dish soap. Use a soft sponge or cloth to clean the inside and outside, avoiding abrasive scrubbers. Rinse thoroughly. Check the sticker edges after washing—if any are lifting, press them down gently while still damp.
  3. Clean the straw and lid separately: Remove the straw and lid, then wash them with warm soapy water. Use a straw brush to scrub the inside of the straw, and rinse all parts well. If the straw is dishwasher safe, place it on the top rack, but hand washing is gentler and prevents damage.
  4. Dry completely before reassembling: Shake out excess water and let all parts air dry on a drying rack. Ensure the straw and lid are fully dry before putting the tumbler back together to prevent mold. If you're in a hurry, use a clean microfiber cloth to dry the inside of the straw and lid.
