And I'm not sure how much TSP to recommend since as I mentioned I use powdered dishwasher soap which has phosphorus in it. (it's also cheaper, and the detergents in it help, too). I'd guess about 1/2 cup or so of DW soap. If the water doesn't feel "slippery enough, throw some more in!
The TSP at the lumberyard probably has directions for concentrations...
I see Loren recommends a cup of bleach per gallon- that seems like a lot to me...I think I use about 1/2 cup of the "ultra" (6%) for a 3-gal wash bucket.
One more tip-
Wet the trailer down first, and wash from the bottom UP
, just like washing a wall. This prevents streaking.
And rinse real well!
About Barkeeper's Friend-there isn't anything chemically superior in it as far as cleaning ability goes unless you're dealing with mineral deposits.
I think it became popular for fiberglass because years ago other cleansers scratched
fiberglass-back then, they had coarser grit for cleaning porcelain on steel sinks, etc. Nowadays any powdered cleanser labeled "safe for fiberglass sinks" will do just as well and will be cheaper.
