A little background information:
I'm writing about this topic because of a discussion on one of my other posts. I'm wanting to put ballast in my rear tires because I have a front end loader on my GT. The discussion can be found here http://gardentractor...-22#entry716517. To sum it up I don't want to use windshield washer fluid because it is flammable. I was thinking about using RV antifreeze instead or Rimguard (beet juice). Some were surprised that washer fluid was flammable so I thought that I would do a new post to help people be more aware.
I was at Walmart today and looked at the Windshield washing fluid. Here is what the labels of Prestone, RainX, and the Walmart brand say:
All of them say "Flammable" which is why I don't want to use it as ballast.
I also looked at a couple of brands of RV antifreeze and the Walmart brands said "Flammable" but the Prestone did not. The Prestone RV antifreeze is $4.65 a gallon (Rimguard is $4.50 gallon at local tire shop) but it does contain anticorrosive additives to protect your rims. My biggest concern is safety. I just want people to be aware that windshield washing fluid can be dangerous and to considered this when using it for a ballast in your tires. The right RV antifreeze is more expensive but it might be worth the extra cost.
This is my $0.02 worth.
