    I only have one spray tank and I use it for weed killer usually.

    Yesterday I rinsed it out really well and put in a selective herbicide and sprayed a couple lawns.

    i didnt think this would be an issue...

    am i in for a nasty surprise...??

    rule of thumb is rinse 3 times...hope you also sprayed out any remaining residue in the wand. If you only rinsed once, good luck.

    Use Nutri-sol.. it's available at farm stores :) Good stuff for tank cleaning.

    No No No. We never mix nonselective in a selective tank. not worth the time. just buy a different tank sprayer.

    I had been using a 2 gallon sprayer to spray some Bayer Weed and Crabgrass Killer to kill off some clover. I wanted to put down some Spectracide on some nasty weeds and ivy so I just got another sprayer. I wasn't for sure what to rinse it with or if there is such a thing so I got another to be on the safe side.

    Uh oh, you better photo copy your license and post it now! The round up police monitor this site heavily.:laugh:

    I assume you drive to your jobs. A truck is a motor vehicle....are you licensed?:laugh:

    You can buy a tank cleaner powder and wash the tank a couple of times. With the time that takes and the possibility of killing whatever you're spraying if you don't clean good enough, the cost of another sprayer is well worth it.

    hmm thanks for the input guys.

    yea i actually rinsed 3x and sprayed out the wand. So I guess I am safe.

    The way I figured though, is that its already diluted from the concentrate.. then you rinse it out 3x.. then whatever remnants are in there are diluted again in 3.5 more gallons.. so i would have to assume there would have to be such trace amounts in it that it wouldnt affect anything.
