Basic ingredients for both Personal and Home care recipes are:
Fels Naptha (or bar soap)
20 Mule Team Borax
Kosher Salt & other various salts
Liquid Castile Soap
Yes there are many many more, however, how well did you pay attention to Chemistry in high school?
If you store Ammonia near Chlorine you might end up with potentially lethal Chlorine Gas?
Ok so you are a pro at storing them safely, are you also going to make sure you don't make TWO Home-Made products in you kitchen one that calls for bleach and one that calls for Ammonia on the same day? I try to avoid bleach altogether now, but be aware these are still ACTIVE Chemicals and can when mixed incorrectly cause problems.
Also take another good long look at the list.
If you are "jumping" on the Home Made, Toxic Chemical Free, Green & Eco Friendly, Allergy Friendly, Asthma friendly, money saving, bandwagon for the first time you may buy many of these items in bulk.
If you happen to be doing a mammoth shop, where you also buy Anti freeze, fertilizer, bleach & various weed killers guess who may end up tapping your phone lines?
Also its a very good way to burn yourself out.
Make one thing at a time to replace what you have used up. Stock pile recipes and slowly gather your cleaning supplies so as to not break the bank.
