believe me, you still get stuff out after HWE. especially commercial.
high foot traffic, those really bad shaded area's where temps sit and spill coffee all day then spin round on there seats trampling it in, M/S bonnetting drastically improves it.
try it with M/S's and see what your bonnet looks like afterwards.
anyway this catalyst leaves carpets hospital level hygenic with a bacteriacide and has flouracarbons as well for after protection, bought some but didn't realise you need heat and i only use the rx for bonnetting, hence the question.
derek
ps...was gonna use it today but only 2 hours til the job so might leave it til i know some more, or might give mat a ring.
