Laser Printing Residue on Medical Grade Silicon 1

[QuinnDeluna]

We are using an Epilog laser to engrave on rubber, but the laser is leaving behind a residue in the engraving that is extremely difficult and to remove. We are currently using rubbing alcohol with a Q-Tip to remove the residue by hand and this requires several deep cleanings to get a sub-par result. This is very time-consuming and will completely bottle-neck our process once we are mass producing these items. Are there any suggestions on a better cleaner to use, or a better rubber material which won't stain? The rubber does not need to be medical grade, it just needs to flex and be comfortable on skin.
Top - Ring after initial engraving.
Bottom - Ring after 15 minutes of scrubbing. Still has white residue in some letters.

Have you tried ultrasonic cleaning?

We haven't tried that. Great suggestion, we will look into it. Thank You.

Thanks. Seems your residue is removable and particulate both pluses for ultrasonic methods.
