Do you just lather it like a regular soap and let the brush soak in a cup?
I get the brush wet first and then rub it over the brush cleaner until it picks up a tiny bit of soap and gets foamy. Then I go to my Timeless lather bowl and fill it up half way with water and then use the brush to make a sudsy dishwater type slurry. I swirl that around for 30 seconds to a minute and then rinse the brush well. Works very well with my water.
