I wash warm or cold depending on the degree of dirty. I also get some residue at the top of the washer and on the agitator. I wipe it off with no issues. I also rotate between all free, micro restore and pinnacle micro rejuvenator.
OPC is the best All purpose Cleaner and yes, it is more expensive. I know that when I grab my spray bottle or put in my wash bucket i'm not going to damage anything, unlike apc+(just my personal experience).
Just wondering how a cyclo compares in time savings to a 3401? Flex came yesterday and i'm curious to know if i will have a place for my cyclo after i get used leto the flex.
