calcium chloride

pony bh · Sep 27, 2011

I have a rim that I had patched because of hole around stem. Painted it inside & out. Let it sit for 2 weeks & haven't put tire & tube on yet, and now it is sweating some thru paint. Can anything be done to help.

I have tried lots of things on calcium soaked rims. The best luck I've had is with my high pressure(almost steam) washer. The combination of heat and pressure seems to finally get the salt out of the pores.

Sandblast the rim before painting seems to kill the rust for me.

Sand blast the affected top layer of rotten metal off. The powerful salt/alkaline solution is still there and active. Prep surface with phosphoric acid.
Thankfully there are better options today than calcium chloride but some stubborn old timers still stick with the stuff.

you can get a salt neutralizer from any marine supply store. works good for saltwater and road chloride. here is a link to one

There is not a thing wrong with Calcium Chloride if you have some common sense. When you see a leak you have it fixed and wash up everything before you put it back togther. You don't have to be a nuclear scientist to figure that out.

Show me a valve stem that seals 100%. Every one seeps a little with salt solution.
Why put up with a deal with a problem when there are other solutions that work without drawbacks?

Mike M · Sep 27, 2011

Phosphoric acid isn't much good as I tried it on a few places on several of my salt eatten vechicles.

You think calcuim eats up rims you ought to see what it does to cars and trucks as they dump it on the roads now !

Calcium Chloride is a more aggressive solution than sodium chloride.
Don't know why people want to hold their enemies close instead of eliminating them.

When I was farming I had all of my tires loaded with C.C. and i never had a seeping valve stem. I just came back from the neighbors place and checked his tractor and no seeping there either. Sorry your thinking just don't fly with me and a lot of other people that I know with C.C. in their tires.

Get this, 25 or so years ago I was involved with dirt track racing. Back then calcium chloride was mixed with water to control dust as racing progressed. The Feds (so I was told) made us stop using calcium chloride because it is bad for mother earth. Since then water only (not as effective) has been used to control dust.

Had luck with some rims, others the cacl seems to get out and rot them. Neighbours knocked a valve stem off when it was faced in, sprayed cacl all over the underside of their tractor and the hitch components. What a bugger of a tractor that is to work on now. Everything is rusted up solid. We free up the hitch, soak it in rustcheck and grease, a month later its seized again.

I unloaded my larger tractors tires right after that. Washer fluid will be all that goes back in if I need it. Prefer steel weights.

buickanddeere · Sep 27, 2011

Why do you persist in wanting something around that sooner or later will require service. And presents a risk of serious damage from corrosion should the valve stem or tire be damaged?
Some guys here think they are a hero because they manage to dodge disaster when others don't.
I don't need the hero feeling so I ballasted my tractors with diluted washer fluid.

No matter if you have C.C. or any other liquid - one very cold day in Dec and every day warmer your tires & rims will sweat. I've seen warm rainy days in winter & spring where water runs off your tires in a dry shed - you'd swear you had a leak. As others have said, if you see a valve stem drip, replace the core ($2 at TS about every 16 years). Rinse well.

S2710 · Sep 27, 2011

I have only had to replace on set of rims due to the C.C. rusting them out and that was on a tractor that I bought with bad rims. I will use C.C. because it works for me and I can't afford the high price Rim Guard and windshild washer fluid will freeze in the jug where I live so I would be stupid to put that in a tire. If the washer fluid works for you more power to you.

I have used calcium for forty years and get along just fine with it, check tires every spring and add air if needed. I do replace a valve every now and then. I have put new tubes in new tires, but not always. I can honestly say I have never had to repair one of my rims, but have done many others. When I have a tire off I use soap water and scrub every thing real good and let it dry before reassembly. I think a lot of tires are repaired in the field and never cleaned cause there real nasty inside. When I do a complete rebuild I sand blast inside and out and use epoxy primer and good paint, rust is hard to kill no matter what caused it. I have heard that washer fluid will rot a tube in less than ten years, any one else heard this??

I am glad CaCl is not used on roads anymore, it rusts cars out very quickly. It packs in with the rock dust and holds the moisture in the cracks.

How cold ?

John_PA · Sep 28, 2011

I didn't read all teh replies, so if someone already said it, then n/m.

Acetic acid.

hose it down with acetic acid, and then flush it with lots of water. acetic acid is the only good way to neutralize calcium chloride.

Sodium cloride is just plain salt right ?

Well here in Ohio they are using what they call "brine" and it just ain't salt. Eats up and keeps eating like the calcium cloride does.
They also use plain salt too.

pony bh · Sep 28, 2011

Thanks for replys , I also brought this tractor from salvage yard needing rim repaired.

Table and road salt is sodium chloride not calcium chloride. Table salt is rather meek by comparison.
