THIS IS FROM A HAPPY CUSTOMER WHO USED THE METAL STAIN ELIMININATOR KIT TO CLEAN UP THE COPPER STAINING FROM THE POOL.

It should be noted that I first tried Jack’s Magic Blue Stuff.  I was able to reduce the copper from about 3 to about 2 but that was it.  After a day or so, the copper level again increased. This was AFTER I replaced the brass ladder and the brass handrail with a new Safeco ladder and handrail.

The Jack’s rep was guiding me, but after the copper level increased, he told me that he could no longer help me and told me to get professional help.

That was when I went online and found Periodic Products.

The results of your products were amazing….as was your friendly advice.

I am a big believer in your products and I will always recommend your products and your support to my friends.

A happy customer!
