Cleaning rust from tank

[Murph]

Yesturday I picked up an old honda 110 for $40. I consider that a steal, it doesn't run, but it came with 2 extra engines. Anyways, inside of the tank that came on this bike is pretty rusted, is there any good way to clean that out? I would like to somewhat rebuild this bike, to make it run. Thanks.

You can get it coated with a special lining. I'm not sure what this lining is called (although Red Lining or something comes to mind), or where you can get it done, I just know thats about the only thing to do.

my dad told me the way to do it is get some naval(sp?) jelly, found in like wal-mart where they have stuff like bondo and such...says the jelly will take the rust out....said that`s how they used to do it back in the dark ages.....LOL

acetone to take the rust out. Kreem to line the tank.

DennisKirk catalog has the whole kit for $29.99

In my limited experience, Red Kote is vastly superior to Kreem. It's holding up beautifully.

Looks like I will be doing this in the near future... Let me ask. If there is only a couple small rust spots can you just use the acetone?

Acetone won't remove rust.

Here is some first hand experience. I just used Kreem on a gas tank about a month ago, worked like a charm. However, I did not use the coating step at the end, I just used the rust remover and cleaner solution. The tank I used it on was extremely rusted to the point of internal flaking. If you shook the tank rust would come loose, that's how bad it was. Anyway whatever you decide to do here are some tips if you plan on using Kreem. When you get the tank off you have to plug the petcock opening, I took a piece of fuel tubing and cut it lengthwise to make a flat piece about 1/2 inch wide and long enough to cover the petcock opening, then bolted the petcock on using the cut fuel tubing as a solid gasket to plug the opening. Also after removing the rust on the bottom and sides internally I had to get up inside the gas cap area. For this I got a screw to plug the air vent hole in the gas cap and just used the gas cap, then I filled the solution from the bottom petcock opening which I removed my stopper from. This made sure all the rust inside all surfaces of the tank were rust free. If you do use Kreem, let the stuff sit overnight for each the bottom and top halves of the tank. Good luck.

A good way to remove the rust before coating it is to put some small nuts and bolts in the tank with a small ammount of gas,mineral spirits, etc. Next shake it all around until all the loose rust gets free from the tank, then dump out all the junk. This may take a few times, but it had worked well for me.

you can use rocks to get the loose stuff off also.
i used a kreem kit on my 350x and it is holding up perfectly.
the tank had literally no rust in it to begin with though, maybe thats why its working good.

Dump a gallon of muratic acid in there and let her eat. Give it about 10 to 15 min and it will be nice a silver looking. Pour it out at this point and wash it out real good with water, then water and baking soda. It will eat all of the rust. Works like a charm.

Hi, I bought an old Moto Guzzi Motorcycle out of a barn and the tank was rusty and half-full of 20+ year old dried gasoline. the paint on the outside of the tank was near mint so I had to be very carefull with what I used. I started by pouring fresh gas in it and letting it set for about a week, then I drained it and most of the gum rust etc came with it, it was still full of surface rust so I sprayed 4-full cans of carburator cleaner in it and let it set overnight, I then drained all that and blew it out with compressed air to dry it up. after it was all dried I poured around 10,000 BB's and shook it in every direction after that i had a gas tank unharmed on the outside and shiny like chrome inside. I cut a small section of old garden hose and duct taped it to the hose of my shop-vac it sucked everylast one of those BB's out and because I was still working on the new fuel lines etc. to get the old Guzzi running, I poured some light motoroil into the tank and turned it every different direction and poured out the excess. that has been 10 years ago and I have never had a fuel problem with it. I am still running those same fuel filters I put on it 10 years ago. I do not like the Kreem or any other coatings. unless you are an expert, it will peel! even if it peels just little bit you will clog your fuel lines, or carb. and then your stuck! as long as your tank is not rusted through this is the best way to do ti yes, it is alot of work, but as long as you keep gas in the tank, and take care of your bike you will NEVER have to mess with rust in the tank ever again.
