Does anyone prefer using a solution tank on a buffer over the traditional mop method? Last night I scrubbed a daycare vct with degreaser and a black stripping pad. Can you use a black stripping pad to scrub vct? I’ve done it before using the traditional mop method (bucket of clean solution, apply w/ mop, then buff) and that classroom floor turned out great! However last night I had a disaster. After buffing the front lobby (least amount of foot traffic) once I made it to the play area, I started getting black streaks while buffing and this black almost paint-like substance began to be left behind instead of the soapy/dirty suds one would pick up with wet/dry vac. I had to do a bunch of extra mopping and with pressure to wipe up the black stains. I simply forgot about flipping my pad so I have no idea if that black “guck” soley came from buildup and me not switching pads? I only did about 500-600 sq ft before the guck appeared. Could my solution tank dispensing solution through the top of the pad to reach the floor cause the pad to die out into floor and solution causing the “black guck”? Or could it simply be me using the wrong pad in the wrong situation? Maybe stripping pads should not be used with solution tank? Im thinking of just returning to traditional mop method because I like to let my degreaser sit for 5 min before scrubbing. Even though it sucks bringing an extra bucket along, I think this solution tank has been causing problems for me.
