Jacks Magic Blue Stuff Pool Stain Remover - Removes Copper & Tolerant

Our review of Jacks Magic Blue Stuff finds it best suited for pool owners dealing with metal stains or high-chlorine maintenance routines. The biggest reason to consider it is its targeted ability to remove copper from water while remaining stable in elevated chlorine levels, making it practical for fountains and heavily chlorinated pools. It is reviewed here as a specialist stain-control treatment rather than an all-in-one cure for every discoloration problem, and users should expect follow-up testing and targeted treatment when existing stains are present.

Key Features

• Removes copper: The proprietary blend is formulated to actively remove copper from pool water, addressing one common source of green-blue staining.
• Chlorine tolerance: The formula remains stable and effective even in higher chlorine levels, so treatments do not break down quickly in standard disinfection conditions.
• Safe for finishes: Can be used on all common pool finishes without causing damage when used as directed.
• Fountain and feature use: Designed to be compatible with many fountains and water features, expanding use beyond traditional swimming pools.
• Clear dosing guidance: Offers an initial and maintenance dosing regimen to help maintain preventative protection and regular upkeep.

Who It's For

Jacks Magic Blue Stuff is ideal for homeowners and pool service professionals who suspect metal stains, especially copper, or who run pools with higher chlorine setpoints. It is a practical choice for fountains, decorative water features, and pools where continued chlorine exposure would otherwise shorten the life of less stable stain products.

Those with extensive, set-in stains should pair this product with a Stain ID Kit first and should not expect immediate removal in every case; some stubborn stains may require multiple treatments or specialized stain removers. Budget-conscious buyers may want to compare cost per gallon with alternative products if price is a major concern.
