2 pcs. 7 lbs. Oxalic Acid Pails.
Oxalic Acid comes in a powder form and can be mixed with water to perform several purposes. We recommend using a mallet to break down any clumps, mix initially with warm water then fill remainder of mix with cold water. In the washing industry we typically use it for:
Wood Brightening, Rust Removal, Fertilizer Stains(as seen in pics below), Neutralizing after using Sodium Hypochlorite & also for Concrete Brightening.
Recommended Ratios:
Concrete Brightening & Rust Removal - Great results can happen at ratios as low as 1oz by weight (1/4 cup) per gallon for concrete brightening. For Rust & Fertilizer Stain Removal dissolve 9oz by weight (1 1/2 cups) per gallon with multiple applications if necessary.
