Outboard Exterior

MarineGEL is the ultimate boat bottom cleaner! Removes barnacles, zebra mussels, algae and rust. Removes calcium build up, waterline and rust stains from all hull surfaces. It is safe on fiberglass, gelcoats and painted surfaces.

Delta’s MarineGEL has been specifically formulated for use on vertical surfaces that come into contact with water and suffer from common water scale buildup. This formulation is especially effective in loosening and removing water scale from boat hulls, tanks, toilets, and from splash-points on cooling tower systems. This unique gelled liquid descaler effectively dissolves all water scale, lime, rust and other water formed deposits on contact.

Before applying MarineGEL, rinse the surface to be cleaned in order to remove loose deposits. Apply MarineGEL liberally to the surface coating any scale present. Allow the gel to sit on the surface for about one hour while it penetrates and dissolves scale buildup. Finally, rinse equipment with copious amounts of available water—no special disposal is necessary. Rinse and dry before any reapplication. Your  boat will no longer show the unsightly effects of constant exposure to water!
