- - E vapo rust (https://www.fordbarn.com/forum/showthread.php?t=226893)

Yesterday afternoon I drained my cooling system and refilled it with EvapoRust.
I'd like to leave it in there for another whole day and night. Will that do any harm?

Leave it in as long as you want. It only attacks rust.

I've heard that heating it up helps it work?

I'll drive it tomorrow to warm it up to operating temp before I drain it. Then I'll put the EvapoRust in the next car. How many times will it work?

Use it over and over until it quits working, about 300 # of rust!
Don't seal it in a container after opening or you will kill it! I drilled a hole in the lid to let it breathe.
I wouldn't get the temperature over about 120* please check with evaporust

Even better try their new product made just for this. It's available at WalMart.

I WOULDN"T start or drive it UNTIL I had drained everything and flushed it out real good. You don't want any debris the Evaporust has loosened getting into your radiator ! ! JMO

Are you referring to the following? Looks interesting.

Thermocure by Evapo-Rust Cooling System Rust Remover and Flush

I filled the cooling system of one of my cars with Evapo-Rust and drove the car around for a 2 days then I drained and flushed. Now everything is clean and rust free.

My experience.

Their advert says that warming the liguid improves its efficacy !
I had it in for about 5 days while driving around. Did a nice job.
It doesn't 'loosen' rust...it devours it,.

Do you put 2.5-3 gallons in your system? or is there a mix ratio to the water?
I might try this soon.

Yes several club members have used it with good results. You must flush it completely or the residue will foam when you put your coolant in.

It seems that if your cooling system if FILLED with evaporust, that the results would be best. But, it is expensive ! So, yes I put a gallon in and added water to top off.
Now, don't get the idea that Model A owners are cheap, eh :) !

Thermocure - Evaporust? are they the same ?
If no which one is better to clean a radiator/block?

So how many gallons do you put in ?

Check out my thread here on this very topic (about to do an update in the next hour or so:

https://www.fordbarn.com/forum/showthread.php?t=226656

I have Thermocure, a product of Evaporust in my block currently (about 72 hours so far). It took about 1-1/4 gallons to fill the block to the top of the water outlet. The 32 oz bottle I bought is good for up to 3 gallons, so my dilution is about double strength. It was about $19 on Amazon with free shipping.

Warning! Science ahead:

Original Evaporust (and probably their Thermocure product) works because of an ionic process called "chelation" (pronounced key-LAY-shun). Basically it bonds electrically with the rust molecules (iron oxide) -- but doesn't bother raw iron, steel or other metals.

Molasses also removes rust through a similar chelation process. It works well, but it's as slow as... well, molasses. It might take 1-2 weeks where Evaporust will probably work in a few days. (And you wouldn't want to put molasses in an engine).

I've used regular Evaporust a lot on rusty parts in the past and have had good success, and so far I'm pleased with Thermocure.

Leaving rusty metal in either one of the products for too long won't hurt anything -- once all of the rust is dissolved, the chemical process stops. You do need to flush/rinse the metal thoroughly when you're done -- but don't throw away your used Evaporust. If you let the rust settle to the bottom, you can use it again several more times until it loses its effectiveness.

Note: I'm not a scientist, but I am always curious about how things work, so I looked this up some time ago.

Hope that helps!

Ok today it's been in there for 3 days and I've driven the car to warm in up. I'm going to drain it today and flush it out several times. Tomorrow we're going on a club tour and when I get home I'll flush it again. Hope it worked.

Keep everyone up-dated :-)

HELP -- What is the difference between Evaporust and Thermocure by Evaporust?

There is a big difference in price. 32 oz for $9 and 32 oz for $20.

This is confusing. HELP!

I think Thermocure is regular Evaporust plus some detergents to break up grease and sludge in a cooling system. It probably has some sort of lubricant effect for water pumps, too.
