Boat Bling Hot Sauce is the ultimate hard water spot remover. It’s made of Bio-degradable, safe, soft-water-based detailer with specialty wax sealants. It quickly removes hard water spots, mineral deposits and exhaust residue without stripping your current wax, adding additional wax sealants with each use. Hot Sauce is designed for Fiberglass, Plastic, Chrome, Glass and all painted surfaces with a spray on, wipe off application. It’s perfect for autos, watercraft, RV's, campers, motorcycles, ATVs, and more. Application Instructions: Begin with 2 Micro Fiber towels – start in the rear of the boat where the spots and buildup are the most extreme, spray and wipe product across 2-3 foot sections, flipping the towel over as you go. Continue around the boat using the same towel until you've reached the front, then use a fresh micro fiber towel for the other side. Use after each day on the water, follow up with Boat Bling Quickie Sauce every 3 months. Trigger color may vary.
