   Just a few questions/comments about antifreeze in winterizing sprayers.
   
   Last year I used Splash -50 RV antifreeze to winterize my sprayer. I had an extra bottle after I was done. I put the extra bottle on top of the sprayer (I wanted an easy way to see if antifreeze was frozen or not) and parked it in the storage barn (unheated.) Let my say also, it was very cold last winter. Got down to -10 or better many times.
   
   Mid Jan 2015 I went to check on things in the barn and I noticed the bottle was frozen. I mean frozen solid. I checked the sprayer and the antifreeze in bottom of tank was also frozen. I moved sprayer to shop to thaw as well as drain, clean and test. Nothing leaked or broke. I left it in the shop till it warmed up. This is the first time I've ever noticed this happen. However, I will also say, I never really paid much attention till last season. Now it's going to be part of my 2 week scheduled check of the barn. I've used this product every year for the last 7 yrs and never gave it much thought one way or the other.
   
   Ok so getting to my questions. Has anyone else had this happen or checked on this throughout the off-season? My BIG question is what are your thoughts on using actual 50/50 green antifreeze in the sprayer tank? I know I would have to catch all the green antifreeze when cleaning out and thats not a problem. I keep coming back to the thought "well, it didn't break with the RV (pink) antifreeze." That's why I keep scratching my head on this.
   
   Thanks for the help and reading this long post about antifreeze.

   Had the same mini panic attack last year. Upon looking into it further this is what I found:
   
   "Q. I had some -50 RV Antifreeze stored in my garage and I noticed it was frozen. Is your product defective?
   A. No. Propylene glycol antifreezes are designed to provide burst protection to temperatures of -50° F or below. Ice crystals will start to form in -50 RV Antifreeze at temperatures around +10° F and will appear to be solid ice at around -10° F to -15° F. Propylene glycol based antifreezes continue to contract and will not expand until temperatures of -50° F are reached, thus providing burst protection for pipes. If you need a product that flows at the lower temperatures, a higher concentrated product such as Winter Ban -100 or our Ban Frost Marine Engine Antifreeze should be used. "
   
   This is a copy from an RV forum but it is consistent with what I found last winter.

   Kris, I also do the same thing as you do with my sprayer and had the same question come up. I had an extra jug and left it on the floor last winter and happened to look at it in the middle of the winter and it was frozen solid, but have never had any problems with my sprayer.

   I blow out the sprayer and with the air compressor so I don't put any antifreeze in. Do the same with my fifth wheel.
