baking soda is a marvel. a book called “101 Uses for Baking Soda” will amaze you. also, borax works well for laundry, as does baking soda. baking soda under the arms, btw, is a great deoderant. you can even wash hair with it (tho no suds, so not so enjoyable. it does leave the hair nice, tho).
not homade, but nontoxic and good for nearly everything (laundry, dishes, counters, floors) is simple green. it’s very concentrated so lasts a long time. (don’t use on glass tho).
for many uses, by the way, simple soap and water are fine. really.
also nontoxic (and works with water only, no cleaners needed) are the new “magic sponge” sponges. they contain no toxins, and as long as you use a lot of water (water makes them work), they will clean better than anything i’ve seen (don’t use heavily on paint, nor use on glass and mirrors). they also make them as mops and other things.
