neutralization

I want to dilute and neutralize excess potassium hydroxide from liquid soap paste but can not currently access citric acid or 'borax' in my current location. People only sell a white substance labelled "Bórax Decahidratado" [or Borax Decahydrate in English]. Its ingredient list says: 99.9%...

I am very new to soaping. Apologies if my question seems silly!! Is it possible to neutralize liquid soap using another acid, such as salicylic or glycolic?

I am about to try making liquid soap for the first time. I don't have borax or boric acid. I was wondering if i can use citric acid to neutralize it? Also, for first timer, which method is easiest? the normal method or glycerin (like soaping 101)? TIA
