Cause honestly what a bloody faff. we moved a few months ago and the previous owner left the bottles of cleaner and whatnot. It's like a system, 1-2-3. Got to use some rough scrubber thing and not to let the fluid dry before washing off then another treatment to use and go to bed.
Is something really bad going to happen if I just use flash? I kinda feel they've created all these products as a money maker scam thing.
