Using WWF is quite common in this area and others from what I have read on other forums.I'm actually shocked that anyone uses windshield washer solvent for ballast that won't freeze. You're never supposed to use chemicals that can effect rubber and alcohol will definitely damage rubber.
I think when you say "salt water" you're actually referring to calcium chloride which is a heavy duty version of the same thing. We who live in the rust belt because that type of chloride is used on our roads get to see our vehicles turn to crap long before they should. It won't freeze if mixed heavy enough and the weight is the "heaviest" you can possibly get for additional weight.
Rim Guard is the best and I'm surprised it hasn't caught on in other areas of the country, but am spoiled since it was invented and made right here in Michigan. The cost of shipping is probably the culprit. I'd suggest taking the tires off the rims and have them sand blasted and painted, then add tubes when putting them back together before filling them again. Rim Guard is bio degradable and won't cause the problems of many other chemicals with one draw back: it stinks like pig sh!t bad LOL!

Tires and tubes have one thing in common: they're both made out of rubber. So, if it destroys a tire it will destroy the tube equally. Automotive antifreeze scares the hell out of me because it's highly toxic where any spillage could result in a dead pet. Everything that uses antifreeze in it has hoses designed and made out of materials that's required to handle it. NOT TIRES or TUBES!Tiredguy,
I would think that as long as the WWF was used with a tube in the tire the alcohol wouldn't affect the rubber of the tire. Does that make sense?
