What kind of alcohol can be used on soap?

[Annavlz]

So you can spray some rubbing alcohol if you want to attach more soap to older layer. Or to remove some ash.
Rubbing alcohol is pure ethyl spirit. But can you use other spirits, such as methylated spirit (violet one)?

Our rubbing alcohol is 70%-90% isopropyl alcohol. I wouldn't want to risk methylated spirits.

I use 90% isopropyl alcohol

I buy 91% Isopropyl alcohol from Walgreens.

Does it really help to "glue" layers/parts together?

 

[lsg]

I haven't tried it without an alcohol spritz so I can't say for sure. Why take a chance though?

Alcohol will help to prevent soda ash on the surface of soap in CP soap. It will not help to glue layers in CP but it will definitely help in MP soap.
