This homemade grout cleaner suggestion is anecdotal in nature. Please read our disclaimer.
When cleaning a bathroom, be sure to pay particular attention to grout which can harbor mold or mildew if not properly maintained. If mildew does start to creep up on you, try cleaning with a toothbrush. Spray or sponge on cleaner, wait a few minutes, then rinse well with clean water. If the stains are particularly stubborn, you may want to use a stronger dilution or repeat process. But if you just want to get it done fast and you are handy with a screw gun, check out the video below for a Fabulous addition to every one's cleaning bucket.
Here is our list of natural products that can be used to substitute commercial household cleaning products. Use them alone, or in recipes to combine their strength and cleaning power.
EarthEasy.com has this to say about Borax...
Is Borax Safe? Borax is considered a mild skin irritant similar to baking soda. The MSDS lists borax as a health hazard of 1, similar to salt and baking soda. A health concern with borax is with its potential to disrupt the reproductive system. Studies have not been done in humans regarding this; however, potential reproductive issues in mice are suspected from high levels of ingested borax. Use of borax for home cleaning formulas, where no borax is ingested, has not been shown to pose health hazards. Borax is a natural substance which is non-carcinogenic, does not accumulate in the body, or absorb through the skin. It is not harmful to the environment.
