Can RV anti freeze be re-used?

[mrad]

Last year when I drained my anti freeze, I put it back in the original bottles.

Can I re-use the anti freeze, or is it not advised?

Given that RV antifreeze is both marginally diluted each time you use it and is biodegradable suggests to me that while you might get away with reuse, it is less than optimal. _I_ won't reuse it, but YMMV.

Exactly. Why would anyone want to cheap out when winterizing an expensive item like a rv. :h

When you put anti-freeze in the lines, there is always a little water still remaining. You can reuse the anti-freeze, just bare in mind that over time it will be a less effective.

I am far from being an expert on this, but I see no reason why not. My maintenance guys recently drained my the radiator on my pusher and reused the antifreeze, so if automobile antifreeze can be reused, don't see why the pink stuff could not as well.
I don't normally have enough pink stuff to make it worth while. I blow out my system with air, put pink stuff in until it runs through all the faucets, run a little into the water heater and the fresh water holding tank, then blow it out again. That second blowing out eliminates a lot of the after-taste of pink stuff.

I reuse mine for tanks and drains, but always put fresh in the lines. You can never be sure how much, if any, it's been diluted, and tanks and drains have room for expansion if it is.
