So what if I'm buying a skid sprayer used that's mainly had Non-selective herbicide in it, from a company getting out of the business?

Can I clean it out? Should I be trying to replace the tank? What other parts should I be replacing?

I'm getting a great deal on it, btw

I would put some water in it and some tank cleaner and spray it out in gravel areas. remove all hose connections at the pump drain all lines tip skid to drain all water out of the tank. Pull the hose all the way out and drain all water blow out with a air hose and reassemble. you should be good to go.

Good ideas above. I don't see a problem with Roundup once the sprayer has been rinsed a couple of times; use tank cleaner and clean all the residue out of the filter, hose and bottom of the tank. Grass will tolerate tiny amounts of Roundup.

However, if you spray trees, bushes and flowers--I would be concerned about the phenoxy herbicides. The odor should be almost zero. I suggest several rinses and then--for your own protection--do a test. With the last 3 icnes of water spray some wild grape vines, tomatoes, dandelions (or maybe a weed tree like box elder). Or buy some plants at the nearest nursery--spray them and wait 48 hours to check the results.

After the spray dries--you may need to bring them inside to a sunny window to avoid the cold.

Grow your own flowers from seed inside if you need to.

This is exactly what I do and have done for years...minus the blowing out with air. If it were a small tank I might though...or you could just flush it more than once

My larger tanks get a quick rinse then I go with the next mix.
Remember, Glyphosate(by itself) is merely a growth regulator that at higher rates kills almost everything. Extremely weak watered down residues of Glyphosate have never posed a problem here when using the tank for lawn apps

Now, if you planned on using the tank for Ornamental T/S apps, more care would need to be taken. I never use the same tank for both lawn and Tree/Shrub apps though... Too much risk involved

Thanks for this thread guys! Ill be keeping my 2gal. for a dedicated glysophate sprayer. Although i dont use it much any longer. Knowing its really bad for the environment, i dont know if ill ever spray it again! Maybe ill wash out best i can and sell it.

I know glyphosate becomes inert on contact with the ground, but I don't know the mechanism. So, I wondered if there's some way to de-activate it in a sprayer other than just rinsing the internals with water a few times.

Triple-rinse and spray out, then run a tank-neutralizer product through it, per label directions.
