Thanks, Roger.  I’m familiar with the nozzles, as my gasoline-powered washer has them (red for the strongest, orange for medium, yellow for mildest — plus a black “turbo-nozzle” for really high pressure, which I’ve never had to use.  I had not thought about the lemon juice idea and magic eraser — thanks.  I’m sure things like stripes and decals (like my boat registration) would be very vulnerable.

I appreciate all the answers on this thread.

For that I use lemon juice diluted 4:1 and a Mr Clean Magic Eraser pad and don’t scrub too hard.  It’s better to let the lemon juice work on the stain for a few hours, scrub, then spray and repeat as necessary.  Be careful spraying around stripes and decals.  The spray will chew them up faster than you can say, “HOLY SHIT!”.  I just spray with water, no detergent.  I consider a good pressure washer an essential boat owner’s tool.
