Mold growth can lead to stubborn stains on upholstery and hard surfaces in your home. Mold is an especially dangerous household irritant because it can cause allergy symptoms and headaches when people are exposed to it. You can call in a team of professional cleaners to remove the mold or you can troubleshoot the problem on your own. Chlorine bleach is an effective mold killer, but you can start with more gentle mold-killing solutions.


The Martha Stewart website suggests using plain white vinegar to kill mold organically. You can use the vinegar straight or dilute it with water if you prefer to start gently. Vinegar works best to remove mold from non-porous surfaces. If you have clothing that has mold on it, you can add vinegar to the water in your washing machine to remove mold stains from the fabric.

Boric Acid

Boric acid is a naturally occurring acid that works well to kill mold, according to the Martha Stewart website. You can use boric acid to remove stubborn mold and mildew. Apply boric acid powder along with water to hard surfaces that have mold growth and use a scrub brush to work the boric acid into the mold.
