HEAVY-DUTY FEED TUB
"36 inch diameter"

This 36" diameter tub is taller than need be (18" tall), but it could be easily cut down if you wanted. Not sure of the inner diameter at the bottom, but if it's at least 30", almost all rear fenders (and front fenders and rims) should fit.

This would sure take up a lot of space in my shop, but now thinking about it, if a lid could be made to fit fairly well, a tub like this could just reside outside in the yard... at least until the temps go below freezing. I wonder at what temperature Evapo-Rust freezes?

I did some bare rims using a small block Chevrolet valve cover.. maybe 14 x 4 x 4. just rotated them every day... no issues with lines. these were not chrome, though they appeared to have some sort of plating at one time
did lots of things in a coffee can.
another way for small parts is a vibratory tumbler. did all kinds of stuff in that one. mine uses little pointy ceramic pyramids. mine was supposed to be used dry but I put Simple Green in it

If you can’t completely submerge the part, soaked towels can keep the entire surface wet. The parts will look horrible after soaking. You have to clean the black residue off with soapy water to reveal the rust free part.

Warming it in the sun speeds up the rust removal. Reclaiming the solution from a floppy tarp is challenging but worth it.

You would have to measure the inner bottom, no way it’s 36”

I have had luck with Oxcylic acid / food grade in a kiddie pool, I realize this thread is about evaporust, but that can be expensive for large items

Check out Nick's before and after OA and clean up.

Another great preservation with an OA bath. This pretty girl from an Iowa farm was in good original shape but was so faded and oxidized as the reds often do. Lots of grease had been applied to the hubs over the years, so chrome was in excellent condition. Nick spent hours carefully picking...

I wonder at what temperature Evapo-Rust freezes?

I contacted them about this several years ago. I was mainly wondering if freezing would damage it. There is s lot of water in it, so it freezes roughly at the temperature water freezes at. Freezing does not hurt it. Thaw it out and use it some more.

One thing I have noticed, the warmer it is the better it works, and when you get down to about 60F the process comes to a complete halt. You can go for days and have zero progress at 60F. Warm it up if you can. My large container (garbage can) was metal. There were some real downsides to that, but the upside was I could aim heaters at it.

I think the consensus has been it's not good to soak only half of a large part like a fender or rim. It leaves a demarcation line.

Why not take an existing tank/drum like a 55 gallon oil drum and cut it 6" up from the bottom. Since it does not need to hold any pressure you could even make it out of a stripe of metal and a plywood base. Buy a 4' by 8' sheet of ridged Styrofoam at your local big box store. Cut some circle disks out of the Styrofoam sheet. A knife blade mounted in a Jig Saw makes a very nice "messless" cut in Styrofoam. The filler disk diameter would be based on the size of the rims/fenders you need to submerge. Use some heavy PVC vinyl plastic to line the drum and cover the Styrofoam filler disks. The purpose of the fillers is to reduce the volume of rust remover necessary to fill the rust bath. I have even heard of people placing red bricks into their tanks to take up volume and reduce the needed liquid material required. It would be a good idea to have this tank sit on top of a table to make it easier to pour the material off and save it for the next job when you're done. I would try to have the tank sit in a sunny area to warm the mixture.

You can buy used plastic or metal 55 gallon Honey drums food drums starting a 20 bucks each. Even the metal ones, just look under recycled 55 gallon drums. There was a place in Mesa, they probably had a half acre of them stacked and all different kinds at Broadway and center.

I came up with a really good solution some years back. My goal at the time was a tub to soak rims specifically.

I ended up getting a plastic water heater tray (Home Depot). They come in several sizes, not all of which are big enough in diameter for a 26” rim. I brought my tape measure and found one that works fantastic.

Some advantages are that it has cut outs to add a drain, the shape is perfect, therefore an efficient use of the product.

Some disadvantages are that you have to fill it to the brim, so messy if you have to move it. Definitely put on small table. You need to rig up a lid of some sort. Also the very top edge of the rim if you’re soaking a built up wheel will barely be submerged. I like to flip and soak the second side to make sure it got a good soak.

The reality of this is that it is still very expensive! It takes the better part of a 5 gallon bucket’s worth to do this. The last bucket I got was like $59. Now it’s over $100. I just did this on my father in law’s bike. I’ve had great success with this method.

For small stuff, I’m always saving plastic containers of all shapes and sizes, which I wash with the dishes and take to the shop for sorting and stuff like soaking parts.

Evapo Rust is an incredible product. It works great on most things from my experience.

I have found recently that it doesn’t get along well with Cad plated stuff. It darkens it up a Lot and makes it look weird sometimes.

Heavy duty plastic bag. Easy to eliminate dead space that way.
