I've tried numerous cleaning solutions and methods, the only thing we found to work is a pressure washer, then a scrub with a stiff brush. We use a pine oil as the cleaning solution, but don't think it matters much what is used, it just acts as a bit of a lubricant for the silicone dust. Hot water in the scrubbing bucket helps quite a bit, as it softens the bands a little. Be sure to run the laser out of focus, we go at least 1/8" or so. Also, be sure to throughly clean them BEFORE they dry, as once the dust gets wet it dries like concrete and is nearly impossible to remove later. We've thrown whole jobs away because of it. Bolder lines and fonts are easier to clean than fine ones.

Thanks for the help.
We shipped our silicone band job a couple days ago. We cleaned with soap water and a stiff brush then blew the water off with high pressure air. This worked ok....Some bands were completely clean and others had a minor bit of ash leftover. Our customer was very happy with our work so I will not worry about small amounts of ash anymore.
Thanks again.

Which way out of focus? Moving the product up 1/8" or down 1/8"?

Move the lens away from the work(above).

Either way makes no difference , the beam is shaped like an hourglass , above or below the "waist" is OOF (out of focus), the downside of moving the material nearer the lens is that you have the optic closer to the smoke and debris that can result and thus can contaminate it.
