Swimming Pool Underwater Muriatic Acid Wash Stain Remover Out Spot OS by Purity
The Out Spot OS is a professional-grade, self-contained underwater stain remover designed to quickly eliminate most stains and fresh rust spots on pool surfaces. Using a controlled muriatic acid application, it works in seconds to lift stubborn discoloration without the need for scrubbing or abrasive tools.
-
Powerful Cleaning Action – Chemical action removes stains and rust instantly.
-
Gentle on Plaster – Replaces harsh pumice stones and scrubbers that can gouge or scratch surfaces.
-
Smart Design – Soaker pad isolates the acid from the surrounding water, concentrating the cleaning power where it’s needed.
-
Quick & Efficient – Each fill lasts up to 20 minutes on a cup of acid, making spot cleaning simple and effective.
-
No Scrubbing Required – The tool does all the work with minimal effort from you.
The Out Spot works on the principle that acid is heavier than water, allowing it to gradually dilute while targeting stains directly at the problem area. This makes it a handy, time-saving tool for pool service professionals and pool owners alike.
⚠️ Important Safety Note:
This product uses muriatic acid, which is not safe for painted, vinyl, or fiberglass pool surfaces. It is specifically intended for plaster pools only. Direct acid application to non-plaster surfaces may cause permanent damage. Always use with caution and follow safety guidelines.

Please be advised that certain manufacturers - including Pentair® (with their TradeGrade® products), Jandy®/Fluidra® (with their Trade Series Exclusive™ products), and Hayward® (with their Expert Line® products) - do not honor manufacturer warranties on specific product lines purchased online.
These policies are intentionally enforced by the manufacturers to prevent customers from purchasing the same products at lower prices online.
Warranty coverage for these products is generally only available when purchased in person from an authorized local dealer.
While we strive to take care of our customers by offering the lowest possible prices on brand new, genuine products, we do not provide warranty coverage ourselves, nor can we guarantee that the manufacturer will honor the warranty on products purchased from our online store.
It is the buyer’s responsibility to confirm warranty eligibility directly with the manufacturer before making a purchase.
If you are a local customer, you may be able to purchase these items in-store and obtain manufacturer warranty coverage. However, for many of our customers across the country, paying significantly more locally just to access a manufacturer warranty often doesn’t make financial sense, especially when some local suppliers charge considerably higher prices.
By completing your purchase, you acknowledge and agree that we are not responsible for warranty support or claims denied by the manufacturer due to their online sales restrictions.
