Water softeners "soften" water by getting rid of hard minerals and other buildup. If left untreated, hard water in your RV's plumbing system can lead to streaks on your shower walls, clogged plumbing, dry or itchy hair and skin after showering, and more. RV water softeners and fresheners from Camping World lead to less mineral buildup (better for your skin, hair, and dishes!) and smoother appliance operation. Stock up and top up today!
