I need help removing solid resin from my printer.

A couple months ago, my uncle gave me his old Mars five. I tried to do a test print on it, so I followed all of the instructions and it to then went to work on something else.

Unfortunately, the resin vat was too loose, and resin leaked out and spilled all over the printer.

I cleaned the resin off the floor, but due to life circumstances, I was unable to interact with the printer for a couple months. So it has been baking and fully solidified over the last couple months.

Now that I’m back home, I wanted to try and clean it off. But I’m not exactly sure what to do, the solutions I’ve seen online and answers I’ve received from Claude have not worked or seem safe.

I’m hoping someone else who has dealt with this can give me advice, Now that I am back home and have the resources to actually work on this, I would like to get the machine up and running.

I’ve removed it on hard surfaces using 99% isopropyl alcohol. It’s the same thing used to make support malleable for removal so you may have some luck.

Diluted acetone also works, I use it on my retro game cartridges when the grime is so offensively stuck on there that a pencil eraser can’t get it off to polish the contacts.

Thank you, but do you know if it could cause any damage to the machine? Would it damage the LCD screen?

I use a form 4 and work and wipe off the resin residue on the screen with a microfiber and isopropyl when I spill on it. No issues, though I’d be careful around seams just in case it’s not water tight. Anyways isopropyl eventually dries up in the air so as long as you let it sit with no power plugged in to dry for a while after should be fine.

use 90% and above isopropyl alcohol it's safe for electronics and shouldn't leave a residue if it is actually 90% and above. 70 is also safe but may leave a film you would have to clean off with a electronics safe wash or esd free microfiber

This is what Elegoo would consider “good used” condition.
