Can't user 5er again this winter - replace red goo in pipes?

For various reasons my RV won't be used again this winter. It was winterized a year ago. Does the alcohol evaporate (to where I don't know)? Should I replace the RV antifreeze before the second win...

If you used cheap AF, with the ethanol, yes the alcohol does evaporate, I would replace it. The higher quality AF, I would just leave it another year.

Also, if ethanol/alcohol version, I'd add more to the P-traps, due to evap, and possible smell from gray tank.
