What's That Smell?

Many Possible Sources

A musty carpet smell can come from many sources, and most of the time you do not know which one it is at first. Trapped moisture is one possibility, but so are pet accidents, spilled food or drinks that reached the padding, tracked-in soil, or carpet that got wet and dried too slowly.

Find the Source Before Treating It

Walk through the room and determine where the odor is strongest, and think about what may have happened in that area: a spill, pet accident, recent cleaning, damp furniture, or a nearby bathroom or appliance. A pet accident needs a different response than a plumbing leak, and a food spill in the padding is different from ordinary tracked-in soil.

Be Careful with DIY Products

Repeatedly applying household cleaners, soaps, or fragrances not intended for the specific problem can add moisture, leave sticky residue, affect carpet dyes, and make later professional cleaning more difficult. When you are unsure what caused the odor, sometimes the best thing to do is stop treating the area until it can be properly evaluated.
