This oxalic gel mix is applied with a brush and agitated gently where staining is worst. Leave for 20-30 minutes before agitating again and washing off with fresh water. It is a very thin gel which, like the Star brite Hull Cleaner, foams upon application. After 30 minutes it was easy to wash off, leaving behind a very clean hull, and placing it in the top tier of products.
