The Ultimate Guide to Washing Kong Dishware in Your Dishwasher: Tips, Tricks, and Expert Advice

Kong bowls are crafted from a durable, food‑grade silicone blend that can withstand typical dishwasher conditions. However, the key is placement. The top rack offers a gentle environment—less heat, fewer direct jets—so the bowls stay flat and avoid warping. Placing them too close to the heating element can cause the silicone to soften or develop micro‑cracks over time.

Another factor is the dishwasher’s cycle. A standard wash with a moderate water temperature keeps the bowls clean without stressing the material. If your dishwasher has a “delicate” or “eco” setting, that’s the ideal choice. Avoid heavy‑load cycles that push bowls against metal racks or other dishes, which can lead to scratches or uneven cleaning.

Not all detergents are created equal. Look for a pH‑neutral formula that’s free of bleach, chlorine, or harsh surfactants. These ingredients can degrade the silicone’s elasticity and cause discoloration. A mild, plant‑based detergent works well and keeps the bowls looking new.

If you prefer a liquid over powder, make sure the liquid is fully dissolved before adding it to the dispenser. Residual granules can cling to the bowl’s surface and create a film that attracts dirt. For an extra touch, add a small splash of vinegar at the rinse cycle; it helps cut through mineral buildup and leaves the bowls sparkling.

Silicone is soft but resilient; however, abrasive agents like steel wool or scouring pads can leave micro‑scratches that trap bacteria. Instead, use a soft sponge or a microfiber cloth. If you need a brush, opt for a nylon one with gentle bristles.

Even dish soap can be abrasive if left on the surface too long. Rinse promptly after the wash cycle and wipe the bowls with a damp cloth. This simple step prevents residue from hardening and keeps the material supple.

Pet bowls can accumulate bacteria quickly, especially if they hold wet food or treats. A good rule of thumb is to wash them after every use, but if you’re on a tight schedule, a thorough dishwasher cycle twice a week is sufficient. Consistency beats intensity; regular cleaning keeps the silicone free of odor and mold.

If your pet has a sensitive stomach or you’re using the bowls for raw diets, increase the frequency. A quick rinse after each meal can prevent the growth of bacteria that thrive in damp environments.

Hot water helps dissolve grease and kill germs, but it must stay within safe limits. Keep the temperature below 140°F (60°C); most dishwashers run around 120°F (49°C) on a normal cycle, which is ideal. If your machine offers a “heated rinse” option, enable it to boost cleaning power without risking damage.

Don’t let the bowls sit in a hot water bath for extended periods. Prolonged exposure to high temperatures can cause the silicone to lose its flexibility and develop cracks. Stick to the cycle’s prescribed duration for optimal results.

Loading Kong bowls with plates and glasses is fine, but avoid placing them directly under the spray jets. The force can push the bowls against metal racks or other items, leading to scratches. If you have a dishwasher with adjustable racks, set the Kong bowls on the upper shelf and shift heavier items to the lower rack.

When you load a full dishwasher, ensure there’s space around each bowl. Overcrowding can trap food particles and reduce water circulation, leaving spots and a greasy residue that’s hard to remove.

Silverware can be safely washed alongside Kong bowls, provided you keep them separated by a silicone or rubber divider. The metal won’t scratch the silicone, but the weight of a full set of silverware can press the bowls into the spray arm, creating uneven cleaning. Using a basket or a separate rack for silverware keeps both items protected.

If you’re using a dishwasher with a “silverware” tray, place the bowls on the top rack and the silverware in the tray. This arrangement ensures each item receives adequate water flow and prevents cross‑contamination of food residues.

Plastic utensils and containers are generally safe to wash with Kong bowls, but watch for heat sensitivity. Some plastics can melt or warp at higher temperatures. Place plastic items on the bottom rack where the water is cooler, and keep them away from the heating element.

Avoid using plastic containers that have sharp edges or are made from low‑quality polymers; these can scratch the silicone surface. For best results, use only food‑grade, BPA‑free plastics that can handle the dishwasher’s temperature range.

Most dishwashers finish in 45 minutes to an hour, but the actual drying phase for Kong bowls can vary. The top rack allows air to circulate freely, so drying typically takes 15–30 minutes. If your machine has a “dry” or “auto‑dry” option, enable it to reduce moisture retention.

If you prefer air‑drying, remove the bowls after the cycle ends and place them on a clean rack. Let them sit for a few minutes before handling; this prevents accidental burns from residual heat and ensures the surface is fully dry before use.

Rinse aid reduces spotting and speeds up drying, but use it sparingly. A thin film of rinse aid can leave a slight residue on silicone surfaces if overused. Test a small amount first: load a single bowl with a light coat and observe the drying pattern. If you see streaks, reduce the amount or skip it altogether.

If you’re concerned about mineral deposits, a diluted vinegar rinse can serve as a natural alternative to commercial rinse aid, keeping the bowls clear and odor‑free without the risk of buildup.
