Easy DIY Steps On Taking Mildew Smell From Carpet Paddings

Mildew shouldn’t be of concern if your carpets get cleaned often. After all, fungi produce mildew after some time of taking root to a particular surface.

However, if the mildew has already gotten stuck in the carpet for a while, the smell is the first flag that can alert you of their presence. If a musty smell starts wafting in your nose every time you come home, then the mildew may be beyond just your carpet’s surface.

Check the following steps to remove the smell from the padding of your carpet.


Step #1. Identify all the padding with mildew

When the musty smell comes around frequently and intensely, it can signify that it’s been a long time since they set in the carpet. The process of dealing with the smell from the mildew starts with finding the source of the scent.

The first spots you should check are near water sources like the kitchen and bathroom. You should also look under carpets that run on top of pipes that could be leaking.

Carpet paddings are installed under carpets so if possible, roll the carpets that had gotten wet or spilled over lately and take them outside. After which, you can then clearly see and check which padding areas have mildew.

Step #2. Clean the mildew

After you find which padding needs attention, you can now start cleaning. While mold and mildew technically don’t eat out of materials, they are usually accompanied by other damaging organisms.

If the paddings are in good condition despite the mildew covering them, proceed with cleaning. However, if the paddings have damage, with holes, excessive tears, or deflation, assess first if it’s still usable.

Cleaning carpet paddings should follow a suitable process for the type you have. However, a general procedure will be to soak it with some water with white vinegar, scrub with soap and water, then fully dry. 


Step #3. Deodorize the paddings

The musty smell from the mildew would often go away after a thorough and critical cleaning. There can be instances that the padding is long soaked with mildew that the scent sticks into the fabric or material of the carpet and paddings.

In such a situation, the first thing we’ll recommend is to hang the padding out on the sun, which means you’ll need to remove them from fastening first. The smell can come from fungi stuck in their inner parts.

Another thing you can do is to get deodorizers for it. There are a couple of available deodorizing products on the market, specifically for carpet pads.

A natural remedy for the musty smell is activated charcoal(usually from coconut) and silica gels. You can use them by putting the paddings on a bag, then placing the deodorizers in there and sealing them.

After the smell has gone completely, you can properly return the paddings and the carpet on top, which should be clean, too.


Can mildew penetrate carpet paddings? 

Yes, if you leave mildew alone in your carpet, the fungi can expand its territory towards the padding and settle mildew in there. Simply put, the longer you leave them, the more of them there’ll be, the worse the smell will get.

The question that should pop up there should then be whether you can do it correctly by yourself and return them well. 

You can attach the carpet paddings at home with a bit of help. However, it would help if you have patience and consideration for a little less than perfect as professionals do it.
