Also, to "seal" the freshly cleaned metal afterwards, a litre of gas with a heavy mix of 2 stroke oil, then slosh that around in the tank for a while and drain. All the tanks I have done that way were excellent afterwards
jpmobius said:bolts look plated or galvanized. They will rob some of the chemical action from the de-rusting, but probably only from the first use as they likely will be bare after a long soak in the first solution. I use pea gravel myself, but admit it is a little annoying to shake out of the tank. Works excellently though.

jetmechmarty said:Electrolysis will cause hydrogen embrittlement, which may or may not become an issue. Metal Rescue is still the best option if you're not following with a liner. That's just my practiced opinion, of course. Given time, vinegar will work as well as any acid.
For mechanical removal, I use rust-cutting resin abrasive. 5 lbs at Harbor Freight is $20. Put a couple pounds of it in the tank and tumble it in the dryer for an hour. It won't cut good metal. It should outperform the sack of hardware,
Tune-A-Fish said:An old used drier is a perfect tumbler... hell it's made for that sole purpose! just need to drill some holes in the batter fins and stretch bungee cords making a web to hold the tank
It's funny you really do have to say that. Wait till classes start, teach. Common sense ain't so common.jetmechmarty said:Just be sure to run it with the heat off!

Depends on the amount of rust. I usually check stuff in timed increments until I have a sense of effect. You'll notice something in an hour at full strength. I've never had to do a tank more than a few hours. I've taken a 1/3 to 1/2 gallon and sloshed it around, dumped out the excess into a bowl. Then go back in an hour and do it again. Repeat until gone.Tune-A-Fish said:The 3rd solution should be here today... One last question... how long do you soak this stuff and full strength or cut with anything??
