Please note: Oxalic is toxic to humans. Citric is not.
VERY toxic, especially to the kidneys. It is great as an electrolyte in electrolytic rust removal baths, but watch contact, vapors, and solutions. I keep a supply ;)

"theWorks" toilet bowl cleaner is concentrated HCL. Nasty vapors, try in hidden area first. Works GREAT on water iron/rust stains, which many are results from coal seams in well water. Should be very similar "type" of stains.

I stack my bags on a skid with plywood on top of skid. No problem.

Years ago, my dad had a gallon of creosote break on the concrete workshop floor. Tried everything to get the stain out after words without success. Them someone told him to try cider vinegar - right out of the bottle. It worked!
