Alright mate,
Virosol is a bit like tfr (traffic film remover) you dilute it to what ever strength you want, some lads have said 4-1 and some say as much as 24-1
I think its just a case of trying a seeing what suits you mate.
The company who make it r called clover chemicals if you phone them ( 01663 733114) and give them your post code they will tell you were your nearest stockists is.
Good luck
