Yes I've had some fun in the past with previous polish getting cake out of the hard to reach cracks, never had a problem with Adam's though the only thing I get is a little fine dust which I can just blow out with a little air.

I had similar problems with hard water and polishing took care of it! Good luck

I have a similar tool but its square works great and you I don't have to stretch to reach the bottom of my dash.

I use the same speeds as above, but I was taught by the guys at adams to distribute the compound across the surface at a speed of 3 before turning it up to 5 or 6. Turned out perfect every time.
