Used Hull Kleen

I used Hull Kleen on my new boat. No harm to the paint. Cleaned the hull beautifully and easily (half hour per treatment) with little scrubbing. No harm to my grass either, which was a little shocking since it eventually chewed up my leather gloves.

Advise to wear mask and rubber gloves though. Lost a good pair of leather outdoor gloves, because I was too lazy to give them a good rinsing afterward.
