wools not too difficult, I dont like going over 11pH which is higher than recommended but always neutralise and dry stroke lots if going high
Hydrogen peroxide I'll go to 6% on wool for spotting (I know some who go higher but I don't, I will sometimes accelerate with UV spotlight)
this was 3 tbspn of pure pottasium metabisulfite to 200ml water and an iron, was working but slow..(I mix stronger for urine or darker more natural looking reds)
so changed to a local product which normally works better for synthetic reds, it will be rebranded I suspect from something you probably have access to?
SDS specs of what I used with heat transfer and acid rinse
I'm no expert but I used to get wool samples and have a play till I was comfortable with my knowledge/chemistry
