We have many in our family that are allergic to nearly everything. Scents, chemical and lots of different things that touch their skin. Borax seems to work in our house when cleaning. So as of late we have been using a combination of borax, baking soda, vinegar and lemon juice to clean our bathroom and kitchen. These are all common items found in the home and no harmful chemicals are present.
Cleaning the sink is easy using a sponge, a sprinkle of borax and a good scrub. Rinse the sponge and sink out. Dry the sink with an old dish towel to make it look shiny. Now repeat this process with your shower and tub.
The toilet is easy to clean using a bit of Borax and scrub with a toilet brush. Borax will help cut the stains in the toilet as well as leave it clean and bright. Add a bit of vinegar and or lemon juice to get rid of the soap scum.
