Customers have mixed opinions on the stain removal ability of Oxalic Acid, with some reporting excellent results in removing old stains from various surfaces like desks, boats, fences, and tiles.

Some customers also mentioned the product's potential toxicity and the need for caution when handling it.
Highlights
Quality
Worked great for removing rust/water stain from white formica that had been building up over 6 years.
This is the only product that got the iron stains out of my tubs and toilets
It took away years of oxidation and brought back the original wood.
After 4 days the stones were bright white.
Price
A great value in this large size.
00 to have a rust stain professionally removed you do the math.
We have already cleaned a lot of quartz crystal for not much money.
Competitiveness
Same main ingredient (oxalic acid) as many way more expensive boat cleaners.

If the crystals are small enough i put them in a crock pot and that works the fastest but just letting the crystals sit in buckets of water if theyre too big for a crock pot works after a few days too
