i have a couple of multipole brushes and decided today to get rid off them as there to stiff and seem to scratch over the glass rather then scrub, i done a job today ,1st clean in 3 years, gave them loads and could still see scratch lines
i have always used ionics old style commercial brushes with no problems but these residentials are no good,the new style commercial brush has the same bristles which also didnt clean the windows very well
im going to try one of alex's superlites & a tucker but the facelift is also supposed to be pretty good
