Gas tank rust removal methods

A. There is a simple solution to remove the rust inside your petrol tank, ......put little stones inside the tank and let it shake and shake (there are more solutions for shaking automatically)....and see the rust is completely removed.....when the tank needs to be as new for many years , there is a special 2 component coating special for petrol tanks.

With friendly greetings, and I hope to hear from you if this is a good solution for you.

A. A nifty trick is to place small stones or aquarium gravel in the bike tank, seal all openings with foam/cardboard and duct tape, "roll" the tank up in a old comforter or heavy blanket, and pack the whole bundle in the clothes dryer with NO HEAT...REPEAT...NO HEAT. I did this on a rust-encrusted 38 year-old custom chopper tank and after four or so hours was able to dump out the crud and rust. Just make sure the wife is out when you do this...it can bring out an interesting conversation...

A. Vinegar [in bulk on eBay or Amazon] let it set a couple days then wash out with water good as new but then you have to seal it with a sealer or it will come back fast

A. I found a good product. It is called "The Must for Rust" from Krud Kutter [affil links]. I used this for my gas tank and it worked great. I was looking for muriatic acid [affil links] but they didn't have any. It was environmentally friendly and all that good stuff too. I poured half the bottle in, let sit for 1 hour, shaking occasionally and then drained. I also used a small scrub brush that I cut in half to fit). After the first time it was A LOT better, almost perfect but I repeated and got it looking like brand new! This was after I tried nuts, carb cleaner, soap and water etc... None of them did much except the loose stuff. TRY IT!

A. First, clean all gas from tank. Duct tape the sides of your opening. So when you put a rod in the tank it will not ground to the tank. Next you need a steel rod; I use threaded 3/8 rod from the hardware store. You need the rod long enough to stick out of the tank about a foot. Now duct tape the bottom of the rod so it doesn't ground to the tank. Also duct tape it where it will lean against the tank opening which should already be taped. Now pour a full round can of salt in the tank. Then fill 95% full of water. Stick rod in tank. Get your battery charger and put positive on the rod and negative on the tank. Set charger to medium. Turn it on. It will take awhile but the tank will start to foam and may over flow some. So have tank in a place where the salt won't hurt anything. Leave on for about an hour. Now shut charger off and pour salt water in a bucket. If your tank needs more rust removed then pour salt water back in and start over. Beware-you can over cook it and cause holes in your tank. Salt water may turn green. I've used this many times on my antique outboard motor gas cans. This will eat your steel rod up after a few uses. Good luck with this very cheap,but efficient way to get the rust out.

A. The best way to going about this problem is to throw in some sort of Phosphoric acid (many cleaning chemicals have this). Another product that works is something called ZEP degreaser [affil links]. I did this for my 69 mustang. Most people throw in rocks or nuts but they are really hard to remove after the process. so I just stuck a chain in the tank and it did the same thing as the bolts would have. Just close off the ends and shake for a good 5 mins, Drain and redo a couple of times. remove the chain with a close hanger and rinse with gasoline. Very easy

A. I have heard instead of rocks and nuts use BB's -- lot easier to get out, haven't tried it. Also was just watching powerblock TV they said 50/50 solution of vinegar and water put in radiator let run for few min will remove rust so would assume would work in gas tank just leave it in awhile and shake once in awhile
