It sounds like the dealer has a vested interest in you buying his product. So maybe not the most unbiased source?

Thanks to everyone. This has been my experience as well, I just wasn't sure that maybe I was missing something important. I can't vouch for taste as I do have a "thing" about water from campgrounds - don't know it's quality or safety. So I drink bottled water. No problem. But all your information is helpful and I thank you.

Tech Tips: RV Antifreeze: Not All the Same

I'm like these folks. They verify the alcohol based products will leave a bad taste and is hard on rubber but it's supposed to be less expensive. You have to read the label to be sure what you're getting.

I've used a lot of the poly-polypropylene antifreeze since I first started RVing in the 1970s. Never had any trouble with a bad taste after flushing it out in the spring.

About 10 years ago, like the folks that wrote the article, I started using my air compressor to thoroughly blow out my water lines and never had any problems. Resuming use just means opening the faucets for a minute or two and letting the water run. I use a cup or two of used auto-antifreeze in the p-traps to ensure they don't freeze up.

Works for me, your mileage may differ. As long as your RV is exposed to freezing weather and you use one of these 3 solutions, you won't have any problems. There's only two alternatives. Store your RV in a heated space or take it to a warmer climate.

Use whatever you want. He's just attempting to upsale you into buying his merchandise (twice) for the same protection to your RV you can get much cheaper somewhere else. Flush well when you unwinterize and there's no after taste. Been drinking from the fresh tank ever since we've had a camper of any kind. Before that, water storage containers, and always out of the old fashioned green garden hose. I'm still alive and kicking!

My two cents worth here. Regardless of what the label says the alcohol-based is toxic. Look up wood alcohol and Gilly juice causing blindness. That said, the amount that is in the antifreeze is small and you will be flushing the system out anyway so it doesn't really matter about the toxicity unless you drink it.

I only use the alcohol-based in the drains and add it to the black tank in freezing weather. The only rubber there are the seals on the dump valves and I keep them greased with silicone.

Although harder to find I only use the propylene glycol which is non-toxic and will not harm the seals in the fresh water lines as the alcohol-based can strip away the oils in the rubber seals causing them to break down.

Same here. Have never used anything but the propylene glycol type and never an issue with taste or odor. Have heard the same thing about seals and alcohol and decided not to take the chance. Cost differential is really not a big deal.

The alcohol used in RV antifreeze is ethanol (grain alcohol), not methanol (wood alcohol). Ethanol is what Vodka is made out of; it indeed is toxic in sufficient quantities, as deaths from drinking excessively prove, but in moderate quantities it's pretty safe, certainly so in whatever residual amount would be left after dewinterizing. Of course drinking the RV antifreeze straight up is not a good idea for many reasons.

Methanol is used as an antifreeze agent in other products, such as winter blend windshield washer fluid, and is indeed pretty toxic stuff if it gets into your body; it doesn't take a whole lot to do significant harm.

I get Quick Siver Propylene Glycol (no alchol) part number 92-M0073196 minus 50 degrees antifreeze. The boat marina where I used to moor by boat carries it. $5.79 per gallon. They also have P/N 92-0073198 which is for minus 100 degrees. $11.79 per gallon. I always used this type in my boat (when I had one) and never really thought about changing. Creature of habit I guess.

Johnson Baby oil is good for the seals. If you empty your black tank you can pour in enough to help the valve seals. I pour in with enough splash to get the toilet seal and when closed I pour a little to sit on top. At least it makes me feel good anyways with having a drink.

Probably vegetable oil do the same thing if you want.
