Underwater Pool Stain Remover
The Stain Remover is a clever device that can be submersed underwater to apply a small amount of acid right on a rust or algae stains in seconds. Simply attach the stain remover to a pool pole and thread supplied hose and cap attachment onto a gallon container of muriatic acid for a quick acid wash. Gravity and siphon action draws the acid into the applicator head and onto the stain. Weight: 3 lbs.
