Tip for keeping cups clean while spraying.........

I picked up this tip online a while back and just thought i would pass it on. Simple to make with a extra quick coupler cover.You just have to make a handle, I used a piece of a common wire.

 You also want to grind down the outside edge of the top so that it fits flush in the hole.

 After spraying green..

Simple, Lift out and rinse off lid with your clean water reservoir on your sprayer or wipe off with towel.
