Not For Gunite Pools Review by Jack
Not so fast! I have a gunite pool with algea and metal stains, especially at the water return outlet. I removed many of them with the "Stain Eraser," but some would not budge. Plus, the Stain Eraser is so small, it's like scrubbing a large blackboard with a pencil eraser. Really hard work!
After reading the reviews and talking with a customer service representative who had no clue about the products, I tried Stain Free and Metal Free together, as recommended. I was very careful to follow the instructions exactly, including the lowering the pH, chlorine and alkalinity to the recommended levels. After 24 hours there was no detectable reduction of the stains. I was able to remove the stains by scrubbing with the Stain Eraser, but that was what I was trying to avoid.
