To clean the waterline and acrylic shell.
Surface-Care quickly breaks down deposits found on the fabric of the spa or hot tub. It is a non-abrasive product and is compatible with the water chemistry, offering a fast but effective method of cleaning.
This product contains phosphoric acid and must be used sparingly as it can mark the acrylic if allowed to remain on the surface for a prolonged period of time. We recommend protective gloves are used when applying.
