Unbelievable product

I use the spray Bar Keepers Friend. I pick it up at Lowe's. Spray on and let run down the hull, maybe hit it with a wash brush, then hose off.

On a side note, I am in the large sport fish business and we use Bar Keepers friend on teak decks to do a soft clean without acid. We use the powder and its eco friendly. Works pretty good at light cleaning and brightening .
