    We are just starting to get freezing temps in this area. My backpack sprayers are stored in an area which is subject to freezing, and every year I take a lot of time making sure there is no liquid left in the bottom of tanks, hoses, nozzles, etc. This year after rinsing everything out I put about 2 qts of windshield washer fluid ($.99/gal.) in each sprayer and sprayed some out to make sure I got the mixture in the hoses, etc. This seems to be a very easy way to winterize sprayers, and the windshield washer fluid is good down to 35 below. In the spring I'll just flush them out .

    Thought it might be a good tip to pass on.

    We have used windshield washer fluid in the past, but planning on using RV antifreeze this year. It's the kind that goes in your drinking water system and a lot more friendly to the environment.

    I just keep mine full all winter. I park the trailer in an aluminum storage shed. It's gotten as low as 20 degrees and my equipment is fine.

    Big difference if you store outside in the open or in a shed.

    I use equal parts of antifreeze and water. Work it through my 200 gallon sprayer, pump it out, do my backpack sprayer and put it all back into their orginal container and save to use for next year.

    Does your 200 gallon stay outside in the weather?

    We use RV antifreeze. You can spray it out on a lawn in the spring and it won't damage anything. They say It's even safe to drink although I'll pass on that. You can get it at any auto parts store. About $2.50.00 a gallon. Good to 50 below.

    I use RV antifreeze and just use it as part of my mix on the first tankful in the spring. But around here it is $6.50 a gallon. I use 4-6 gallons in a 200 gallon sprayer so that it will run through the entire system, hose, etc.

    I never use anti-freeze. Just drain them good. Small hand held and back pack sprayers, I just drain them, put the cap on, pressurize them, then blow the remaining water out the hoses. Done it this way for over 20 years and never had a problem. Coldest it has gotten here was around -12.
