    Will 1/2 gallon of RV antifreeze mixed with 210 gallons of water be enough to damage cool season grass?

    No it wont cause any problems, I would spray your hose into the tank for a few minutes just to make sure you don't spray it undiluted onto the lawn. but I think RV antifreeze is bio degradable anyway.

    It should not as it is safe to drink. It is used in the drinking water system in RV,s. If it is safe for humans it should be ok for grass. We have been using it for several years for winter shipping and it has not been a problem. Dilute it and shoot it.

    Thanks guys. I cleaned everything out of the tank and hose on my skid sprayer, but I forgot to turn on the pump agitation before filling it. I turned on the agitation after dumping herbicide in and out shot pink antifreeze right into the tank. I was in a hurry, should have ran water through it.

    I would think at a 200:1 ratio I shoud be okay.

    Better you than me. let us know what happens.
    And by the way... regular antifreeze is tough on grass...I have seen a few spills--killed it dead.

    I winterize my tank every year with 4 gallons of rv antifreeze and I don't clean it out. I hae a 200 gallon tank. It doesn't cause any problems at all.
