How do I safely clean cured resin/debris from the bottom of a Form 4 resin tank?

Hi everyone,

I’m using a Formlabs Form 4 with High Temp Resin V2.

I recently had a print failure because I used too few supports. The model detached from the build platform and fell into the resin tank, leaving some cured resin/debris stuck to the bottom film.

I filtered the resin and ran the Cleaning Sheet procedure, but unfortunately the debris is still firmly stuck to the film.

What would be the safest way to remove it without damaging the tank?

Has anyone had a similar situation with a Form 4 + High Temp Resin V2? Is there a specific technique for removing stubborn cured resin from the film when the Cleaning Sheet doesn't work?

I’d especially like to hear from people who have actually dealt with this rather than replacing the tank immediately, since the tank is brand new.

Thanks!
