Well, I don't know if I do it "right", but I handwash, then I put in bleach water and then I run through my dishwasher on the sanitizing cycle! LOL Maybe overkill??? or heck, maybe I just do it really wrong all together!!! LOL
Water is the culprit. If your product does not contain water or another liquid such as aloe vera juice or a milk, then that amount of sanitizing is not necessary. When I make my lotions and body butters that use e-wax and a water (known as water in oil, or oil in water) I do the extreme sanitizing routine. When making whipped shea butter, things like this, I just wash the equipment, then spritz with a shot of alcohol and dry with a sanitary cloth. I do use anti oxidant oils to help the butte from going rancid. I use T-50 which is a natural vitamin E. Again, if there is water in the recipe, sanitize and use a preservative.
If you have a beauty supply in your area, you can find a hospital grade disinfectant (QUATS) at a reasonable cost. Be sure to read the label and follow the directions. You may also look into a UV Sterilizer Cabi - which can be found for $100 to $150 on ebay. If you need help with ordering from the proper companies at a good cost, let me know and I would be happy to help out.
