Speaking of sprayers... I noted that after using Bonide fruit tree spray for my apple trees I would get a little white film left in my backpack sprayer even after rinsing it out well. I bought this tank cleaner at TSC and decided to just clean out all of my sprayers at once...

I mixed up about 30 gallons for my 110 gal sprayer (1 oz per 3 gallons of water) and ran some through the boom a little and then let it sit overnight.

The next morning when I pumped out the cleaning solution, I collected some of the cleaner in jugs and used that to clean out my backpack sprayer and other sprayers as well. Pump out some of the solution through the hose/s as well and it will clean up your nozzles as well.

This is what the film looked like in my backpack sprayer even after I thoroughly rinsed it with water...

Here is what it looked like after sloshing around some of the cleaner in it - clean as a whistle.

I would say the FarmWorks tank cleaner works very well.
