Description
Spot-free rinses don't last forever. When the minerals start sneaking through, swap the cartridge and get back to driveway-quality finishes, no toweling, no streaks, no second pass.
These are the OEM replacement cartridges for the Boats N' Roads ZeroSpot™ System, built to drop straight in, packed with high-capacity deionizing resin, and ready the moment your last one quits. No adapters. No fittings. No hardware-store guesswork. Twist the old one out, twist a new one in, and you're back to rinsing dry on glass, gel coat, paint, and chrome.
Two cartridges per pack.
