How to Remove Rust Stains From Diamond Brite
Diamond Brite is a finish used on pools and other outdoor surfaces. The surface is composed of quartz and Portland cement, creating a hard and durable pool surface. Because the material is made with cement, the rust stains are handled similarly to how you would tackle a rust stain on your driveway or basement floor. Treating rust stains on the bottom of your pool is a slightly trickier problem. Always start with a natural, gentle method before moving on to harsh chemical cleaners. Drain the water to get to the stain. Consult the care and cleaning instructions for your pool for instructions on draining the water.
Pour vinegar on the stain to completely cover the area. Choose either white or apple cider vinegar. Let the vinegar sit on the stain for 20 minutes.
Repeat pouring vinegar on the stain and let it sit for another 20 minutes.
