Like I mentioned above I am using this in conjunction with silicone sheets which I lay in a baking pan in the well of my sink. I soak them in soapy water. The silicone prevents the chips from spinning. This way I don’t have to hand hold them. I can just hit one side of a whole batch at once and then flip them over and repeat. The sonic scrubber thing has a slide switch so it just stays on. No pressure needed.
there is also a Rubbermaid branded one but it just wasn’t in stock for me. Also I have only experimented with the brush head in the main photo not the other accessory heads. I will try those eventually.
