				I am using tfr this week and wondered if you use it as per the instructions ??
Would it be harmful to up the dose ?

				I would use as per instructions, just leave longer on or re apply, I cleaned this office building last year and that was best, DONT try the high strength as it made are skin itch

				i have upped the dosage before Dave, never had a problem but don't leave on longer than say 5-10mins, i have done this on a car before and it burnt into the laquer, left a vary faint mark. I've never had a problem on glass or plastic frames yet but its only cause i'm very cautious with it.
