Boat Juice Extreme Boat Water Spot Remover, Hull & Boat Cleaner, 32 oz | Lifts hard water spots, scum lines and salt film from gelcoat, glass, chrome, vinyl and aluminum, no rinse, margarita scent

REMOVES HARD WATER SPOTS & SCUM LINES: Easily tackle stubborn water spots, calcium buildup and scum lines after a day on the water. This 32 oz water spot remover and hull cleaner breaks down the mineral residue left behind by lake water and saltwater.

GOES BEYOND A REGULAR WASH: Soap and water may lift dirt, but they will not dissolve the minerals that dry onto your boat's finish. Boat Juice Extreme easily clears those spots and the waterline scum, bringing back the gloss in your gelcoat so your entire exterior, from hull and topside, looks freshly detailed.

SPRAY ON, WIPE OFF: Mist one section, let it sit for about a minute, then wipe with a microfiber towel and buff dry with the clean side. No rinsing needed. Work out of direct sunlight for best results. Wipes away clean with no film left behind.

SAFE ON ALL SURFACES - ON AND OFF THE WATER: Use on gelcoat, fiberglass, painted hulls, glass, chrome, vinyl, aluminum and plastics. Works on everything from wake boats, bass boats, and pontoons to jet skis, cars, trucks, and RVs.

SWEET MARGARITA SCENT, MADE IN THE USA: Skip the harsh, vinegar-based cleaners. With 1,000+ sprays in every 32 oz bottle, one bottle covers a full season of wipe-downs, and every pass leaves your boat smelling like sweet margarita instead of nasty chemicals!
