Oxalic acid

Oxalic Acid, from Florida Laboratories, worked wonders cleaning the rust spots off our pool deck. Diluted with water, applied with a small brush, left for 30 minutes, power washed - beautiful! Thank-you!

Mineral collector's friend

As any mineral collector knows Iron stains can ruin the appearance of a specimen. Thankfully Oxalic acid safely removes iron from stone. Made from Rhubarb and highly effective this product simply beats other methods hands down.
