Default Car Mechanics / Chemists

I am winterizing my fresh water system - first drain then with the pink stuff and put it in and then check the faucets for pink and none comes out - add more none comes out.. Then I realize I had a bad smell so added chlorine bleach earlier this season and can smell a bit of chlorine. So I do a test and sure enough if I add chlorox to the pick stuff it turns almost clear - so my question is, did it kill the antifreeze properties???

I took a sample and I am going out now to get a tester - anyone want to take a guess?

Just a guess, but I think you WILL lose some of the anti-freeze properties.

EDIT: what kind of tester are you going to get, and how are you going to test the anti freeze property of anti-freeze?

No impact. Bleach is removing the pink coloration that was added to give the tell tale color of non-toxic antifreeze.

Hey NJ

The cheapo density float the ball (densimeter?) tester like you would with your car. Shows you at what temp. the stuff will freeze.

Or I maybe will just throw it in the freezer

Thanks Backtosea I hope you are right.

Tester works with ethylene glycol (dog killer stuff) vs propylene glycol (found in human food) if I recall correctly.

I am actually taking an uneducated guess. Pump some of the solution into a small container and put it in your freezer to see what happens. i do not think the standard testers will work.

even if it works, not sure i would want to have a high concentrate of bleach sitting in my pump for a long period of time. It will degrade certain parts. I know on my pool chlorine feeder the gasses destroy my o-ring seal in the cover if i leave it on the feeder over the winter.

Thanks

Its slushy and almost solid after a few hours at 0% in the freezer . I am letting it warm now to see where it turns totally liquid. Ok at 8 degrees its almost totally all liquid and at 12 degrees its basically liquid. So I am all set.

The hydrometer ($1.79 at ACE made by Custm Accessories - Tiawan) I bought shows 4 floating balls with the stuff supposedly meaning good till -30.

But to make sure it works I tested it with water and it did the same thing so its no good for anything - Imagine trusting it with my car's antifreeze?

I agree about the chlorine hting maybe damaging rubber type parts I will blow it out of the pump just to make sure. But there is only a slight chlorine odor - mostly smells like the pink stuff now.

But honestly - you got me - I didn't even think of the double entendre..I am slipping in my old age - need more pink stuff

One can never have too much "pink stuff"

Bob Bob Bob, how many times have I told you about the cheap stuff? Good thing you double checked it.

edit: as far as the pink stuff goes, I have no guess. BUT, I wouldn't be sniffing the blend of pink stuff mixed with bleach! Who knows what kind of toxic concoction it now is?

As I was posting that I said - here's some good fodder for Garett! It was only a matter of time.

Is your hydrometer made for propylene glycol? There are specific hydrometers for ethylene & propylene, check at your local auro parts store. You all so have to tap the hydrometer with your finger nail to break the surface tension and get any air bubbles to rise to the top otherwise it will hold the balls upand they won't sink, just like the do with a syringe before they give you a shot.

Im not 100% sure of all the ingredients in the pink stuff, but I would not expect any significant reaction between beach and propylene glycol.

In all reality I would doubt any chlorine is left in the bleach at this point, assuming it has been there a while. If the area experienced high temps (ie summer) then almost for sure no hypochlorite is left, it decomposes quickly at high temp.

The bleach won't effect the protection of the antifreeze. It merely "bleached out" the dye.

This is why I like THT so much. Virtually any post can go into the dirt within a couple of posts, yet still be informative! Education, with humor!

That was my assumption (post # 6), which would explain why the pink stuff read similar to water. Ethylene glycol has a different specific gravity.

Flush your water system and start over. Don't mix bleach and a glycol-based antifreeze. Bleach is a solution of sodium hypochlorite. Propylene glycol (RV pink antifreeze) will react like ethylene glycol (auto antifreeze). According to the chlorine institute if you mix sodium hypochlorite with:

Organic Chemicals and Chemical Compounds such as (Note 1):
Fuels and Fuel Oils
Amines
Methanol
Organic Polymers
Propane
Ethylene Glycol
Insecticides Solvents and Solvent Based Cleaning Compounds



You could get
  1. Formation of chlorinated organic compounds.
  2. Formation of explosive compounds
  3. Release of chlorine gas, may occur violently
You don't want any of the above going on in your pipes, nor do you want to drink water containing the reaction products.

Thanks to all

Alhtough there is nothing to ignite the explosive by product gases I certianally will add water (its already drained) redrain and redo. Plus the smell is no stronger than a swimming pool or city tap water. But obviously has enough to eat out most of the pink.

BTW the hydrometer did work (showing water to freeze - the balls did not float) a day later and several rinses later. Apparantly even a small residue either lifts the balls or remains in the balls or their surface for a while.


So anyway if any terrorists are listening about the explosive gases stuff from the very cheap antifreeze and bleach, you should know that you MUST pre-mix all this stuff in a glass container (for safety) in your tent with your friends while lighting up one of those dung cooking fires.
