Semi official instruction from FormLabs staff

1. Use the scraper to scrape out as much resin as possible.
2. Use the squirt bottle to squirt IPA into the tank while holding the tank upside down so the IPA can drip out. You don’t want the liquid pooling in the resin tank as it could seep under the silicone, destroying the tank. You can use the scraper to wipe the silicone.
3. Place the resin tank upside down on a paper towel to let the IPA drip out and dry.
