cleaning after laser cutting

[janwan]

We are laser cutting flat gaskets from silicone rubber sheet. What is the best way to clean ashes from the edges of the gaskets. We were trying ultrasonic with DI water but results are not very promising. Any suggestions will be greatly appreciated.

Die-cutting is probably better solution but due to thin walls we decided to try laser first.

The "ashes" (white oxides) should wash away readily in soap (or detergent) and water. But the black, molten, sooty crap won't come off without mechanical means.
