Hi all! Well my quest to find Metal Magic in Canada has proven fruitless🤷‍♀️
So I just bought Ascorbic Acid and will pour it down a pvc pipe on the stain. (Pump off). These are my questions:
1.) How much Ascorbic Acid do I put on a stain? (The pipe is about 6” in diameter)
2) Do I leave the powder on there until it dissipates, or should I be wiping it off?
3)
