How to Get Rid of Biofilm in a Dog Bowl

To get rid of biofilm, empty your dog’s bowl and scrub every surface with hot water, dish soap, and a clean brush or sponge, paying particular attention to the rim, bottom, and any seams or folds where the slippery coating can collect. Rinse thoroughly until no soap remains, then let the bowl air-dry completely before refilling it with fresh food or water.

Wash food and water bowls daily rather than waiting until they feel slimy, and replace your dog’s drinking water with fresh water throughout the day as needed. A quick rinse alone may leave the film behind, so use soap and friction each time; if your dog eats wet food, wash the food bowl after each meal to remove residue promptly.

For an extra cleaning step, sanitize the bowl after washing it by using a pet-safe method suitable for its material, such as a dishwasher’s sanitizing cycle if the bowl is dishwasher-safe. If you use a disinfectant, follow its label for dilution, contact time, and rinsing, never mix cleaning chemicals, and make sure the bowl is completely free of product residue before your dog uses it again.

Smooth bowls are generally easier to scrub than bowls with deep scratches or hard-to-reach crevices, so replace a bowl if damage makes it difficult to clean thoroughly. For a foldable bowl such as our Collapsible Silicone Dog & Cat Travel Bowl, open it fully and scrub around each fold, then let it dry before collapsing it for storage or travel.
