Topic: blaster parts cleaning solvent and evaporust.

[Don R]

 I spent some $$ on shop chemicals. I've been parts washing in old gas and can't stand the smell and fire hazard anymore. I took a chance on Blaster brand parts washer solvent, the soapy water just isn't getting it done.
  The evaporust is a 4 gallon bucket with no pour spout, I'll need to make something up for a valve. I have my brothers flake orange K4 tank to de-rust as well as a rusty K2 tank with a lovely paint job.
 
  I've used a plumbing hose bib, a close nipple, a hose washer, a conduit lock nut and a couple electrical box knockout reducing washers for a makeshift drainer bucket when I was a plumber/fitter. Maintenance men copied my bucket to avoid fixing leaks so it sort of backfired. I called it the DonCo Drainer, it's not a slicer, not a dicer, it's genuine plastic made right here in the USA of unknown origin borrowed parts, so don't accept imitations. Patents not pending.

Get the original!

I like it! Gonna have to scour one up...
But isn't that bucket 5 gallon not "4"??
I hope you bought it from home depot on line, $79.99 delivered to your door step. That's where I got mine last year.
I just did a search again and see amaxon has it at a whopping $144...... unbelievable. Gotta watch them....
I've been cleaning out rusty tanks for friends with it besides my own tanks. Thinking I need to order another bucket of Evaporust so maybe that DonCo Drainer is the hot ticket. I've been bailing the bucket using a wide mouth funnel (with screen in it to catch big particles) and a used 4 cup sized RSS screw container to do the bailing.

Looks like they have a 3.5 & 5 gallon buckets available...

I need to do a tank too.  1 gallon wont do the job??

[Don R]

   This one is the 3.5, I guess.  I tried a gallon once but it was cold and I read here recently it's way less effective  in the cold. The tank was excessively rusted too so I assumed the tank rust overwhelmed the gallon of evaporust. 
  I've been using muriatic acid but I want to preserve the paint on a couple of them.
  My concern with solvent is what to do with it when it's used up.

No. 1 gallon won't do the job.
For heavily rust tanks, start with an electrolysis cleaning first, rinse with clean water, then fill with Evaporust. Then rinse with diesel fuel 4 times.

The tank I need to do is not heavily rusted.  Thanks

 My drying routine is rinse with water, then alcohol, shop vac exhaust air to dry, then 2 stroke oil thinned with some gas.

We have done a whole stack of gas tanks with EvapoRust and skip the water rinse. There's no way I'm putting water in a freshly derusted tank. We rinse with diesel. Pour around a gallon of diesel in, close the cap and shake the crap out of it. Immediately dump it into a clear jug and in a couple of minutes the sludge will settle to the bottom. Then carefully pour the diesel back in for another round and dump the sludge. Four or five rounds and the tank will be ready to use or store. The residual diesel in the tank will have no effect on the bike when you fill it up with gas to use.

This sounds like a good method that I will follow.  two questions:

1. What do you use to plug the petcock bung? I was thinking of using some type of plumbing plug.
2. Is two gal of evaporust enough?

Thx

I use a pvc plumbing cap on the 75/76 tank bung. The tanks have a Japanese pipe thread so the pvc won't bugger the bung threads. I put some Teflon tape on the bung to help it seal.

5 gallons of Evaporust is what I use to fill the tanks. $80 delivered to my house through homedepot.com

 I should qualify my rinse plan, since I failed to explain that is what I did with muriatic acid.
 I am surprised that evaporust leaves sludge behind for the diesel to flush out. I'll modify my procedure accordingly.
 To plug the early style petcock, I use two bolts with teflon tape and a plastic vacuum cap with a screw in it. A PVC cap sounds like a good plan for late tanks. F2 tanks might require another idea since the nipple got smaller.

We use 5 gallons of EvapoRust and the sludge is what's left of the rust.
We also just leave the petcock on, the EvapoRust doesn't hurt it and cleans out any rust residue in the petcock. Afterwards we clean up the petcock and put new seals in.

The petcock needs a rebuild so I can just use it. Thx!
