I have a pressure washer a brush and need help on cleaning solution. Someone told me about a really good siding cleaner but I can't remember. Any thoughts?
Is this vinyl siding? I would not use a pressure washer. If you get water in the seams it will never dry and you will have mold /mildew problem in time.
Let the chemicals and scrubing do all the work, then just hose off with normal water pressure.
I use Duke concentrate in an old Windex window wash bottle. (the stuff for exterior windows). That and a quick rinse with ol' garden hose work like a charm.
