yeah john, got that tanning out of that tile i was on about, just ordered a case from texatherm, used it on a wool rug that had coffee in, wicked stuff.
use carefully though, makes white rugs even whiter. think it'll be brill on cotton tassled rugs. what course we on next?

i need an upholstery course and seriously thinking of hard floor and leather restoration.
