How to Clean a Washer with Vinegar: What Works and What Doesn’t

You read online that vinegar is a natural washing machine cleaner. You had a gallon of white vinegar in your pantry, so you poured the whole thing in the drum and ran the hottest cycle. The drum smelled fresher for about a week. Then the odors came back, and three months later the rubber seal on your front-loader felt sticky and the door didn’t seal properly. Vinegar can freshen your washer, but using it wrong causes damage that costs more to fix than the vinegar saved.

Cleaning a washer with vinegar is the practice of using distilled white vinegar to freshen the drum surface and remove light odors from a washing machine. While vinegar can provide a temporary freshening effect, it is not a replacement for a dedicated washing machine cleaner because it can’t reach internal components and its acidity can degrade rubber and metal parts over time.

To clean a washer with vinegar safely, use no more than 2 cups of distilled white vinegar in a hot cycle no more than once every 3 to 6 months. For regular monthly cleaning, use a dedicated washing machine cleaner. Don’t pour vinegar on rubber gaskets, don’t mix it with bleach, and don’t use it on every cycle.

What Vinegar Does When You Clean a Washer

Freshens the drum surface. The acetic acid in vinegar breaks down odor compounds on the drum surface. A hot cycle with vinegar can make the drum smell cleaner temporarily.

Dissolves light mineral deposits. Vinegar’s acidity can dissolve light hard water deposits on the drum surface. For heavy deposits, a commercial descaler is more effective.

Removes light detergent residue. Vinegar can help dissolve thin layers of detergent residue on the drum surface. For thick buildup, a dedicated cleaner is needed.

What Vinegar Can’t Do

Can’t clean internal components. The areas where most buildup hides are the outer tub, internal hoses, drain pump, and heating element. Vinegar in the drum can’t reach these areas effectively. A dedicated cleaner like affresh Washing Machine Cleaner is formulated to circulate through and clean these internal components.

Can’t remove thick buildup. Vinegar is a mild acid (5% acetic acid). It can dissolve light residue but can’t break down thick, hardened deposits of detergent, fabric softener, and minerals.

Can’t kill all bacteria and mold. Vinegar has some antimicrobial properties but isn’t as effective as commercial cleaners at killing the full range of organisms that grow in washing machines.

The Safe Way to Clean a Washer with Vinegar

If you want to use vinegar as a supplement to your regular cleaning routine, here’s how to do it safely:

Step 1: Pour 2 cups of distilled white vinegar directly into the drum (not the dispenser).

Step 2: Set the washer to the hottest water setting and the longest cycle.

Step 3: Run the cycle with no clothes in the machine.

Step 4: After the cycle ends, wipe the drum with a clean cloth.

Step 5: Leave the door or lid open to let the drum dry.

Do this no more than once every 3 to 6 months. For monthly cleaning, use a dedicated washing machine cleaner.

What to Avoid

Don’t use vinegar on the rubber gasket. The rubber gasket on front-loading washers is the most vulnerable component. Vinegar’s acidity breaks down rubber compounds over time, causing them to become sticky, brittle, and eventually fail. Clean the gasket with warm water and dish soap instead.

Don’t use vinegar on every cycle. Regular use of vinegar in the drum can degrade rubber seals, gaskets, and hoses. Use it occasionally for drum freshening, not as a regular cleaning method.

Don’t mix vinegar with bleach. Mixing vinegar and chlorine bleach creates toxic chlorine gas. Never use both in the same cycle.

Don’t use more than 2 cups. Excess vinegar doesn’t clean better and increases the risk of damage to rubber and metal components.

Don’t use vinegar as your only cleaner. Vinegar can’t reach internal components or remove thick buildup. Use a dedicated washing machine cleaner for monthly maintenance.

The Right Way to Clean Your Washer

For regular monthly cleaning, use a dedicated cleaner:

Drop one affresh Washing Machine Cleaner tablet into the drum and run the hottest cycle. The tablet is formulated to clean the drum, internal tub, drain pump, and hoses without damaging rubber or metal components.

For the rubber gasket (front-loaders): Wipe with a cloth dampened with warm water and dish soap. Pull back the folds and wipe inside. Don’t use vinegar.

For the detergent dispenser: Remove the drawer and soak it in warm water. Scrub with an old toothbrush. Don’t use vinegar, as it can discolor the plastic.

For the drain filter (front-loaders): Remove and clean monthly.
