We make biodegradable cleaning products that remove water scale from your pool, spa or home.
Our Story
We started Piranha over 10 years ago because we were having the same frustrations as many pool owners, that pesky white line was making our pool look ugly and nothing we tried worked. So we looked far and wide and found the world’s best industrial descalers and brought them to our backyard and now yours. There’s nothing magic about our products, its just chemistry that simply works.
Piranha Spray
Our spray is for safe and effective removal of smaller areas of calcium deposits, and other water born mineral deposits. It works like muriatic acid but it won’t burn your skin. There’s no pungent odor, it’s safe for the environment, and is great to use anywhere you need it, in the backyard or the bathroom.

Piranha Gel
Our gel is for heavy duty water scale removal on spas, pool water lines, and other water features. The gel is a highly concentrated formula that sticks to vertical walls to enable longer times of contact between the acid and a calcium area. This product is fully biodegradable and neutralizes with water. Comes in a 32 oz wide mouth bottle.
“Wow...great product. Pulverized calcium build-up regardless of how heavy it was. Excellent stuff.”
— Donald S.
“This stuff is the bomb! It melted away the calcium deposits on my pool. So easy to use and it works fast. I’ll never buy anything else for scale build up.”
— Vince H.
We tried several different pool products and household cleaners to remove calcium/scale from our pool tiles. This product is a bit pricey, but you don’t have to use much to clean your pool. Well worth the price! Took the water down to expose the tile, applied with two inch paint brush, waited 15 minutes and removed. Clean tile!
