Mix baking soda with 1 Tbs. of fabric softener and spread on your mattress every one to two months. Leave the mixture on for an hour and vacuum off. This formula will kill dust mites and freshens the mattress. See website for many more homemade cleaning recipes.
Add orange peels (or any citrus peel) to a quart of white vinegar in a closed container and let it set for two weeks. Combine citrus/vinegar solution half/half with water and use for cleaning. Works on floors, tile, fixtures, etc. Smells good and is tough on scum! Best of all there are no chemicals.
