“Dear Dr. Dogterom,
Thank you for your response!
After some trial and error, I found the best way to clean the resin was with boiling hot water. I submerged the trays in the water and let them sit briefly to allow the resin to soften. I then scraped each channel clean using a small screw driver wrapped in cotton gauze. The material picked up the sticky mess and I adjusted the wrapping as I went so that I did not simply redistribute the mess. A very light residue remained, but was no longer tacky after cooling. Overall this process was very effective and fairly efficient – I had quite a few trays with resin, but was able to quickly clean them. I found it best to work with two trays at a time. Sincerely, Kat B. 🐝
