@eyekey, I agree with the other responses, using .15 touchpoints is too small. If you want to use very small touchpoints, you need to have larger anchor touchpoints to hold the model in place.
When you have a print failure, you can start with using a gloved hand and inspecting the resin tank for debris, but the best way to ensure that it’s clear is to use the cleaning sheet. I’m sure once you increase the touchpoint size, you’ll have fewer failures and waste less resin.
