question about rims

Ellis Kinney · Jun 7, 2018

I have been cleaning up a pair of rims for a neighbor. The rims were exposed to calcium, but not in bad shape. I have been using the wire wheel, scrubbed
with Dawn dish washing liquid and power washed. After one coat of paint I notice a few beads of calcium water oozing from the metal in a few places. What
chemical or process can be used to stop this? Ellis

Calcium chloride is a salt, not an acid or alkaline. Really the only "chemical" way to stop it is to flush with clean water, but you'll never get it all because the salt has corroded up into the metal, much in the way a carpenter bee chews into wood.

Only other thing I can think to do is to bake the rim at 250 degrees for an hour to boil out all the moisture before painting. Without the moisture and air the salt can't produce the iron oxide, rust. You'd need a pretty big oven for a rear tractor rim, though.

The answer about it being a salt is right on. If you google 'how to neutralize salt on metal' you will get many answers that may or may not work. One of the easy ones involves mixing granular gypsum or limestone with car wash soap with some water and scrubbing with that. I don't know - it's a tough question but one that others with collectable machinery have dealt with hence the many returns on the internet search.

I always sandblasted my rims and then painted them. Seemed to work out the best. I also removed the tires and did the rims inside and out and always used brand new tubes when putting the tires back on.

you could also add vinegar to the water and wipe them down. basically need heat. warm them up with tiger torch. not much else other than washing.

Wonder if getting it real hot with a torch would work?

Might be possible to make a small bonfire the diameter of the rim. Once the fire burns down to coals and the smoke is all but gone, use a loader to put the rim on steel frame or concrete blocks to keep rim above the coals. That would easily heat the entire rim and dry out the moistur. Another idea is a propane weed burner.

I have no answer to your question. Had my rims sandblasted and hot dip galvanized; bet that got the rims hot enough LOL. Not a single trace of rust.

I have a metallic bubble in one of my rims near the valve stem that needs welded and painted and I fear I will have this same problem in the near future. Thanks for all the tips.

Two on U'tube. Give 4hese a try. 5he ones that I am trying to find are how museums preserve items that were removed from salt water. Havent found anything yet. The one with the battery charger makes much more sense.
rust disolve.

Here is the battery charger. Give it a try.
electrolysis

I have a pressure washer that is not a steam cleaner, but almost. The boiler does not have a thermostat, only a high limit switch. All that to say, the water gets very hot! The high pressure and heat has worked for me. It apparently really penetrates the porous metal and gets the salt out.

FOR ME A RESEBUD TORCH POPS RUST OF FAST. BEST TO PROTRCT EYES FROM HOT RUST.

Ellis, what I want to know is how did you identify the liquid as calcium water and not just plain water?
