The Safer Spa & Pool Acid

Acid Magic is the best product for dissolving calcium deposits on filter cartridges, and for cleaning tile and concrete. Use liquid Acid Magic to more effectively reduce high pH and total alkalinity in spas and pools. *

  • Equal activity to Muriatic Acid
  • Less fuming issues
  • Safer handling - does not burn intact skin
  • More effective in reducing high pH than dry acid products
  • Very economical to use -- a little goes a long way
  • Superior for filter scale cleaning
  • Great for cleaning salt chlorine generator cells 

Acid Magic offers the advantages of liquid acid products while nearly eliminating many of the dangers, including skin burns and toxic fumes. Dramatically more effective in reducing stubbornly high pH and TA than dry pH Decreaser.

Filter Scale Removal

Removes Filter Cartridge Scale

Muriatic Acid washing of filter cartridges is a problem because of dangers associated with product handling. Acid Magic is equally effective in removing calcium deposits, but much safer to use. It's easier on filter media, so filters last longer. 

First clean filter with Power Soak or Eco Soak, rinse, then soak the cartridge in a solution of one part Acid Magic to twenty parts water until all bubbling stops. Presto! Scale is gone! (Read and observe all safety precautions on bottle).

Product notes: For pH adjustments, start by using 1 1/2 oz. of product per 500 gallons water, if pH is above 8.0. (2 tablespoons = 1 oz.) Check with test strips to determine additional adjustments. Diluted Acid Magic is great for cleaning salt chlorine generator cells, such as Nexa Spa. Read bottle instructions and precautions before using. Contains specially-buffered hydrochloric acid.

*Acid Magic is not registered for pH adjustment in California.

32 fl. oz.

Much better than plain muriatic acid
Identical to regular acid in performance, but much more pleasant to use.

Good stuff!
I run into some particularly nasty cleaning problems in my residential cleaning business. One of them is dirty bathtubs with certain types of stains that have been nearly impossible to remove until I discovered Acid Magic. It's used in place of Muriatic Acid and advertised as a safer alternative-- that's what caught my eye. It will not burn the skin, although I have found that it will sting, if you have a cut or open sore. It definately has a lot less fumes than Muriatic Acid, however, you still do get some fumes that require you to have open ventilation. When I use Acid Magic, I wet the area to be cleaned and let it sit for at least 20 minutes or so, while I do the rest of my cleaning away from that area. I have found that extra time gives the acid time to work and time for the fumes to dissipate. After letting it sit, I usually only have to use a wet rag to clean out the tub, but occasionally it will take a second application to get all the dirt and grime clean if the tub was really groaty or has calcium scale issues. I've had success using Acid Magic on tile, porcelain tubs and sinks, brick & concrete, and at home have used it to remove stains & scum from my boat hull. One thing to be careful of, like Muriatic Acid, it will slightly etch concrete. Overall it's is a better choice for me than plain Muriatic Acid and it sure makes my cleaning jobs a lot more pleasant!

Not as advertised IMHO
Although the product does work as well as muriatic acid, when used full strength, the claims of 90% less fumes only apply to the first couple of minutes of use. If you apply this product to a heavily calcified area and leave it soak, for a few minutes, the resulting fumes are every bit as potent, if not more so, than muriatic acid.
