|The Underwater Acid Wash works via a continuous feed of acid from a bottle above water. This tool removes any stains that a conventional acid wash can, with a lot less hassle, time, and cost.
Ideal for small or large patches of stains, it can even be used to perform a complete acid wash when draining the pool is not possible or preferred.
Because most of the acid is used in the chemical reaction with the plaster (due to the complete contact made by the unique soaker pad), pH levels are only minimally affected. Adjustments to pool chemistry are usually not needed for average jobs.
Note: This tool is truly equivalent to a conventional acid wash in the amount of acid it can apply to the surface. Therefore, care must be taken to not apply excessive acid to any one area. This tool should only be used by a trained service professional.
