Brush soap or ivory soap will emulsify (break down) the oil in the paint, which will help us to remove and wash away any paint with water.
Remember that oil is impervious to water.
That means that if you just take your oil paint brush and put it in water, the water is going to bead right off of it. So what we need to do is break down the oil with soap and then wash it.
Understanding that oil and water don't mix is key to understanding how to clean oil paint brushes.
Drag your brush back and forth along the wet bar of soap.
2: Clean Your Oil Paint Brush Well
To begin, take your bar of soap and run it under the faucet to get it wet.
Then drag your brush back and forth, flat side down, across the soap, working the oil out of the brush.
Be careful not to push the brush directly down because it will bend the bristles. Simply drag it along, flat, in each direction.
You'll see the soap will start to foam up and oil will begin to come off the brush.
Rinse your paint brush off and continue to drag your brush back and forth along the soap.
3: Rinse Your Paint Brush and Repeat
At this point, your brush is going to get covered with some murky foam. This is the soap and paint coming off the brush.
At this point, just rinse the brush and then come back to the bar of soap and repeat what you’ve done so far.
When you're first learning how to clean oil paint brushes you may tend to stop cleaning before you get every last bit of paint out, so make sure to continue this step until the brush comes completely clean.
You'll know when your oil paint brush is clear when paint no longer comes off of it, on your soap and a piece of paper towel.
4: Knowing When Your Brush is Clean
You’ll know your brush is clean when there's no paint coming off it. Both the bar of soap and a piece of paper towel used to dry the brush will show absolutely no tint of color. It will be completely pristine.
When finished and the brush is clean, take the brush and gently pitch it to make it flat like the way it was when you first got it.
Let it dry that way and then in a few hours, it'll be ready to be used again

Dish soap does a pretty good job on brushes but I recommend you purchase a bar of Ivory soap which will last you longer. Be careful what you buy. Ivory soap is probably the best one.
