How to Clean and Disinfect Ice Trays

Over time, ice cube trays get dirty and harbor germs. If your ice cubes have started to taste a little funny, it’s because they’ve absorbed the odors of frozen food in your freezer. You can get rid of both germs and absorbed odors easily by using either a vinegar or baking soda solution. Placing an open box of baking soda in your freezer can help to reduce odors and keep your ice tasting clean.

Pour the cleaning solution into the trays. Fill up each little cube section in your trays with the baking soda solution. Allow the trays to soak in the solution for a few minutes. Set any remaining solution aside; you may need to use more of it.^{[3]

- If there's some sort of grease stuck in the trays, you can also spray some degreaser and let it sit for a couple of minutes.
- Another option is to spray an all-purpose disinfectant.
With the trays still filled with the solution, use a washcloth to scrub each cube section. Be sure to get down into the nooks and crannies. Use the washcloth to go over the plastic between and around the cube sections, as well.^{[4]

Turn on your warm water tap and hold the trays underneath it to rinse away the baking soda solution. Keep rinsing until you no longer see any baking soda residue and the water runs clear.^{[5]

You can put them on a dish rack to dry, or simply use a clean cloth to dry them. Once the trays are dry, refill them with water and place them in your freezer as you normally would to make ice.^{[6]

Place an open box of baking soda in your freezer. Ice trays (and the ice inside them) absorb odors from other items in your freezer over time. This often results in bad-tasting ice cubes. An open box of baking soda will soak up odors in your freezer and drastically reduce what your ice trays absorb.
- Replace the backing soda with a new box every 30 days for best results.
- Make sure all of the food in your freezer is packaged tightly to reduce odors.

Fill your sink with warm water and your usual dish detergent. Place the ice trays in the water. Use a cloth or sponge to scrub the trays to remove loose debris and any lingering ice residue. Rinse them thoroughly with clean warm water.
Measure out 1 cup (120 mL) of white vinegar and pour it into a very large bowl or bucket. Add a gallon of water to the container. Mix the solution with a spoon.
Push the trays down several times so that they’re completely submerged in the solution. Some ice trays may stubbornly continue to float. If this is happening to you, put something on top of the trays to weigh them down.
Once they’re submerged in the vinegar solution, let the trays soak for a minimum of two hours. You may want to put the bowl or bucket in a safe place where small children or pets can’t get into them.
Remove the trays from the vinegar solution. Dump the solution down your sink drain. Hold the trays under your faucet and rinse them thoroughly with clean water.
Place them on your dish-drying rack, or you can wipe them dry with a clean towel. Don’t forget to dry the underside of the trays, as well. Once completely dry, refill them with clean water and freeze them as you normally would.

It's not as acidic as its 'classic' counterpart, so it is not recommended.
