How To Clean Mould Off Freezer Seal

Question: "How to get rid of old mildew stains on refrigerator gaskets"

With warmth from the outside air and moisture from the interior of the fridge, gaskets around your refrigerator/freezer doors can quickly become the home to mold and mildew. The first step is to kill the source and then prevent it from returning. There are several ways to approach this black monster.

Hydrogen Peroxide Method

You Will Need:

Hydrogen peroxide
Spray bottle
Soft cloths
Cotton swabs (optional)

The Removal Process:

Begin by cleaning the area as normal to remove as much dirt as possible.
Fill the spray bottle with undiluted hydrogen peroxide.
Spray the affect areas.
Allow the spray to sit on the stain for several minutes.
Wipe away with a clean cloth. Cotton swabs can be used to clean out crevices and other nooks.
Repeat as necessary.
When all of the black stains are removed, clean the area as normal to remove any hydrogen peroxide residue.

Bleach Method

Bleach is a killer of all germs including mold and mildew, but it can also dry your gaskets out. In extreme cases, it may be a necessity, but approach this method with caution so that your gaskets do not become dry and crack.

You Will Need:

Bleach
Water
Spray bottle
Soft cloths
Cotton swabs (optional)
Lubricant (ex: Vaseline)

The Removal Process:

Wipe the area down to remove as much dirt as possible.
Combine one part bleach with two parts water in the spray bottle and mix well.
Apply the solution to the stained areas and allow it to soak for several minutes.
Wipe away excess bleach solution using the soft cloth. Cotton swabs or old toothbrushes can be used to remove growth in tighter areas.
Repeat only until the stain is gone. Be cautious not to dry out or damage the gaskets with excessive bleach usage.
After the stain is removed, clean the area thoroughly to remove any excess bleach.
If the gaskets appear to be drying out, apply a lubricant as necessary. Vasaline works well, as does olive oil or coconut oil.

WD-40 Method

A lesser known method, WD-40 has been effective for removing many types of stains, including mildew.

You Will Need:

WD-40
Soft cloth
Cotton swabs (optional)
Mild cleaner

The Removal Process:

Clean as much of the dirt and mildew away with normal cleaning methods.
Spray WD-40 on the stain and let it set for a few minutes.
Wipe away using the soft cloth and cotton swabs for tighter areas.
Repeat as necessary until the stains are gone.
After the stains are gone, clean using normal cleaners to remove all traces of the WD-40.

Additional Tips and Advice

Vinegar makes a great protective barrier against future mold growth. Rub white vinegar on the walls and gaskets of your fridge to ward off future attacks of mildew.
Vinegar can also be used to clean mildew stains, but may not be as effective as the methods above.
