Maintaining a dishwasher sometimes involves a little extra cleaning, much like you would frequently clean your sink. This is because dishwasher detergent tends to dry on and becomes quite a hassle to remove. Detergent doesn't just rinse away like soap once it has hardened.
Things You'll Need
Spray bottle, 20 oz.
1 cup white vinegar
2 cups distilled water
Add 1 cup white vinegar to the spray bottle.
Add 2 cups distilled water to the bottle. You can use tap water, but distilled is far cleaner. Shake the bottle after the lid is on to blend the vinegar and water.
Spray the vinegar and water solution directly on the spots where the dried dishwasher liquid is caked and stuck. Let the solution sit for five minutes.
Spray a bit of the vinegar water on a rough dish sponge. Do not use a metal scrub sponge.
Wipe away the dissolving soap with the sponge. Rinse the spot with water.
