I would like to know, from a purely chemical point of view, if the following is effective:
Someone makes soap with stainless steel
equipment (i.e. bowls, blender, spoons etc.). This includes adding sodium hydroxide to distilled water, and then combining the lye solution to oil.
Thereafter, one proceeds to:
- Rinse the equipment thoroughly with cold water.
- Then rinse the equipment with vinegar.
- Then wash the equipment for a third time with dishwashing soap and water.
Do these steps make the stainless steel bowl safe to use for food again?
I'm not asking whether it is recommended or not, there are a lot of opinions about this on soap-making forums.
I am just trying to confirm whether these steps will sufficiently clean the equipment, so that it is safe again, from a chemical point of view.
Is it enough to dilute with water, neutralise with vinegar, and then wash again with soapy dish water? Just doing my research, and I'd like to hear from someone with knowledge in chemistry, rather than the varied opinions of home soap-makers.
