There are many books, websites, magazines articles, etc... that give MANY different recipes. I use just a few that work for most things. I'm going for less clutter, too, so I don't feel the need for 20 different bottles under my sinks.
For general cleaning:
#1
1-2 tbsp Dr. Bronner's liquid soap (I don't actually measure- I just squirt some in. I use peppermint or tea trea oil (TTO) for their natural disenfecting qualities) OR non-toxic dishwashing liquid (I like 7th generation)
Water
Mix in a spray bottle. Shake. Squirt where dirty. That's it!! Easy cheesy!!
#2
50% vinegar
50% water (amt. depends on size of spray bottle)
Mix in a spray bottle. Shake. Squirt where dirty.
Do NOT use vinegar on marble!! It will ruin it!!
#3
Hydrogen peroxide
Put in an opaque spray bottle (very important as peroxide degrades when light hits it). Spray on surface after vinegar for added disinfecting qualities. Great for cutting boards!!
For heavy-duty cleaning:
#4
baking sodaa couple of squirts of Dr. Bronner's liquid soap OR non-toxic dishwashing liquid
water (enough for consistency)
Mix together in a bowl until consistency is a little thinner than paste (if you add too much liquid, balance it out with more baking soda!!) . Use with a scouring pad or scrub brush to scrub just about anything!! Sinks, faucets, bathtubs, etc...
#5
lemon juice
salt OR baking soda
Mix into a paste. Let sit for a few minutes. Scrub away!
These are what I use most of the time, but the key is to find what works best for you!! I get my scrub brushes and spray bottles from the dollar store, and they work really well!! Dr. Bronner's can be found at most health food stores, some Targets, some grocery stores, and online. Most of these recipes were used for generations by our grandmothers and all those before them. Toxic does not equal clean. New does not equal good. Maybe we should learn from those who came before us. Sometimes simple (and inexpensive) equals BETTER!!
