Scrubbing bubbles at work!
While we constantly demonstrate how well our ultrasonic bowling ball cleaner extracts oil, we have said all along that we're fantastic at cleaning grime and dirt too!
This video gives a really great visualization of surface dirt being removed from an OIL FREE ball. As you can see, the detergent creates a foam in the area where surface dirt exists - then when the dirt is released through the action of the ultrasonics, the bubbles float away to the surface! It's pretty cool to watch actually!
