Rusty tanks....

[Al Goodwin]

How do y'all take care of cleaning them out?

[sctparker]

I've always used muratic acid it's cheaper than the rust remover stuff

I think Mark used vinegar in my GS tank. Maybe he will chime in soon.

"The Works" toilet bowl cleaner, undiluted.  Find it at K-Mart or Wal-Mart.

Do not dilute it. 

Fill tank about 3/4. Let the tank sit for 15 minutes on each side.  Drain the tank.  Rinse the tank very well with water.  Now you must displace the remaining water.  Use WD-40.  Spray the inside very well.  Liquid WD-40 works much better.  Now get about a cup of gas and swirl around in the tank. Pour out gas.

Done.

Take it to your local radiator shop. They have the best and most inexpensive thorough cleaning and sealing process. Go figure, lol.

After I've cleaned them out in the past I've used marine gas tank epoxy to coat the inside of them. It's good enough it will seal pin holes permanently if needed. I've done this several times and ridden for years on the tank without any problems.

I've put a  bunch of screws, nuts, bolts, ect. in the tank and shake it to break the loose rust loose.

I've had good luck resealing tanks using POR-15

same principle but I usually use a transmission fluid and a bag of ice. the cubed kind. fill it, shake it, drain it. it will have a good coating of anti rust and you don't spend an hour trying to bounce out that last nut or bolt

I use a length of chain for ease of removal afterwords. if you plan on repainting the tank after just tie the last link to some string and tie that off around the tank, then shake the piss outta it.
