If you live in a wetter region of the U.S. you likely must constantly take time to remove mold from the wet parts of your home. Fortunately there are many more environmentally friendly remedies to sanitize your home without the need for abrasive commercial products to remove mold. Many commercial products use bleach and sodium hydroxide to clean mold residue. Regrettably these chemicals are both highly corrosive and are a health risk if used in a location of your property that is not well ventilated. Likewise these chemicals can remain in an aquatic environment for a extensive period of time which not only presents a issue for the areas fish populations but also can be destructive to our drinking water source. On the other hand you could use citrus or grapefruit extract generally about 20 drop mixed with a few cups of water can sanitize moldy areas. Likewise you can try mixing roughly 1 part vinegar with 3 parts water then put on and let dry. If you have a stubborn mold stained area you can mix 1 part of vinegar 1 cup of water and 2 tablespoons of baking soda in to a paste. Then scrub in and allow to dry. Likewise, Borax is an environmentally gentle dish washing liquid that can be mixed liberally with hot water and used as a spray to not only clean mold but also anything else in your home as well. If you have a really tough time with some of these, the strongest natural cleaner is tea tree oil but unfortunately it is the most costly of any of these natural products as well. To apply tea tree oil just pour a tablespoon into a spray bottle and dilute with water. Then simply apply and let dry, and wash with water. If none of these do the trick you could have to try a bleach product, but if you have to just attempt to use it as sparingly as possible.
