After a long search for a bucket, or contraption to use for rinsing my oil brushes. I decided to make my own.
I took a wide mouth canning jar, any jar will do, but, I liked wide mouth. And took a piece of window screen (fine metal mesh) and cut it small enough to make like a ball shape to fit into the bottom of the jar. Filled just above the screen and walah! A perfect cheap way to rinse your brushes.
The residue will fall beneath the screen each time you rinse. Just make sure not to rub real hard. You will mess up the bristles.
I have been using this for about 4 years now and have not purchased any new brushes in 4 years. It works really well.
