Ready to de rust my tank

tshadow6 · Feb 18, 2013

I finally was able to remove both fuel petcocks today. I was unable to loosen the last bolt, (it was beginning to strip) so I took the whole tank to my local hardware store. A clerk that looked like a retired 1% pointed me to the right screwdriver bits. I had the bolt off in the parking lot 5 minutes later. Should I use the washing soda/battery charger technique or solvent and nuts/bolts?

Either method works but once you do this you should have some sort of tank liner job done. It will quickly flash rust otherwise.

You can mix a little gas and oil and slosh right after you de-rust and seal. That will take care of the flash rust. I will never use any sealer again. Tony C

You had a bad run with Kream or similar product?

I've had nothing but great success with the por15 kit. Done 3 tanks with it, with no issues

Check out my post in the carbs section. I don't bother with sealers either. Once you have the tank clean you shouldn't need it if cared for properly. If it's still crusty inside, you're not done yet.

I've heard por15 is best. reviews on the creme were bad. I bought some por15 to use but decided not to. To get rid of rust I used Muratic acid/water soution with nuts and bolts on a wire.. It ate the Rust out in less than 5 min. then rinsed with water a bunch ... compressed air blow dry then 2cycle oil and gas coat.. I figure plain metal is best.. just use a secondary fuel filter.

No I just found it is not needed after you clean your tank and fill it.

So forgive my newb question here, but what exactly is the 'proper technique' for caring for a tank. Other than the obvious keep it full of gas. To be perfectly honest, ive never done a thing to any bike tank ive ever owned. Only one had a rust problem, and that was when i rode it away from the dealer!

Does muratic acid effect the steel of the tank? I use muratic acid to get rid of oil stains on my driveway.

I just went through all of that with mine. Ultimately, I removed the rust mechanically, then finished the job with phosphoric acid. I used the Caswell liner. It looks good now. You can follow my whole process below.

Failed Tank Liner

Too many stories about tank liners going bad and no way to remedy them except burning them out, no thankyou. Electrolysis is amazing and cheap, phosphoric acid after that for a protective coating and to stop the flash rust, hot water and baking soda rinse after that to neutralize the acid and quick drying, use soft water if possible.

Phosphoric acid is available as Ospho, naval jelly or some toilet bowl cleaners.

Dilute the Phosphoric acid with water and avoid contact with good paint.

Electrolysis is done with Arm & Hammer Super Washing Soda, not baking soda.

I've used metal rescue with good results on my z50 tank

White vinegar, 5 percent acidity. Fill the tank and let her sit in a warm place. Check after a day or so. Don't tell anybody.
