I just bought 24 gallons of washer fluid for 75 cents a gallon.
Unless somebody can give me a good reason not to use it by Saturday, this is how I'm going to do it. Valve stem up, valve core removed, jack stand under axle to keep the tire round. I have a 12V DC bilge pump in a bucket with hoses adapted to the right size. Pump in the fluid until it slows down or stops flowing. Remove the hose to bleed pressure from the tire. Fill with more fluid. Keep doing this until fluid comes out of the stem. That's about 75% full and that's where I'm stopping.
P.S. The only GOOD reason that I would be worried about, is the alcohol eating the innertube. So, if anyone has proof of this I'm willing to listen because I'm absolutely positive that the calcium destroyed my valve stem and ate away part of my rim in less than 2 years. There is NO WAY that calcium is going back in.
