For those that do it, can you explain your technique for cleaning a bullnose like the one pictured and the riser? What about corners and those pie shaped areas on cases that turn?
I have a little square OP machine that John G sold me years ago. Modified Argo machine with two handholds. Will get close into a 90deg. corner and can be easily rotated over the nose and riser in most cases.
Prespray with Multisprayer hand agitate with Handi Brush, especially bullnose, pad with auto buffer. We use the same Handing Brushes when HWE. They are cheap, lightweight and inexpensive.
