Purity Pool OS Out Spot Stain Remover

Model: OS   |    Mpn: OS   |    Ean: 0855931002117   |    PartNumber: OS   |   Asin: B004VLB3VE

Purity Pool is a family business founded in 1961 by an experienced pool service professional. Since all Purity Pool Products were designed first for professional use, durability and efficiency have always been top priorities. The Out Spot is a self-contained underwater stain remover. The cup holds about a cup of muriatic acid. Once filled and connected to a standard pool maintenance pole, the Out Spot can be lowered down to the pool surface and placed on top of a stain. Since acid is heavier than water, the acid seeps through the pad (slowly diluting, so go for the worst stains first!) over a period of about 20 minutes. Most stains are gone in seconds!

Features

  • Fast and easy with no setup
  • Small amount of acid used will not affect pool chemistry
  • Gentle application of acid is much safer on the pool surface than other stain removal methods
  • Since the pad is just for applying the acid and not for scrubbing, will last years when used correctly
  • Handcrafted in the usa with pride
