How to Get Rid of Mildew Odor

How To: Get Rid of Mildew Odor (3)

STEP 1: Locate the mildew growth causing the odor.

Sniff around. The first step in getting rid of a mildew smell is to locate the source of the problem.

Remove impediments to your search. In the bathroom, that means taking down the shower curtain and temporarily relocating toiletries that would obscure your view of the likeliest breeding grounds (e.g., grout lines or tub caulking). In the basem*nt, pack up old newspapers, cardboard boxes, and any other disposables. Focus your attention on surfaces vulnerable to moisture.

STEP 2: Scrub the mildewed areawith diluted bleach.

If you’re successfully able to isolate the mildewed area, that means you can spot-treat it without going through the effort of cleaning the whole room. However, if you’ve searched high and low but cannot find any obvious mildew growth, cover all your bases by giving the entire space a once-over.

In a large bucket, mix one part bleach to four parts water. Scrub the walls and floors with the homemade mildew killer you’ve concocted, being sure to spongeaway all bleach residue once you’ve finished the job.

STEP 3: Clean off the bleach and wash any affected fabrics.

Scrubbing the walls and floors isn’t necessarily going to cut it, though. It’s not uncommon for the smell of mildew to emanate from fabrics, such as towels, and from other personal belongings (e.g., sneakers). Can the mildewy item be placed in the washing machine? If so, soak it in all-fabric bleach for about 30 minutes. After rinsing it off, run it through the washer as you would a normal load of laundry.

With regular attention and the occasional use of a few household staples, you can get rid of that mildew smell you hate so much, along with the hazardous, unhealthy mold those smells belong to.

How to Prevent Mildew Older

Of course, the best way to get rid of a mildew smell is to prevent it from developing it in the first place. An arsenal of tools can help you keep your spaces dry and clean and mildew-free:

  • Installdehumidifiers in problem areas; with the humidity level low, mildew cannot grow.
