Wash evaporated - left a mess at the bottom

During the pandemic we went WFH and left everything. All of the IPA evaporated out of the wash, leaving a sticky somewhat hardened mess at the bottom. The stirrer is now glued in place. We’ve only used White FLGPWH04, so that’s what’s in the bottom. I’ve tried adding some IPA back to clean it up, but it hasn’t been very effective at dissolving the resin, which appears to be partly cured. Is there a solution to recovering this tub, or do I need to replace it, and is it possible to replace just the tub part of the wash, since everything else seems to be in perfect condition?

Hello @bobbaddeley -

I’m sorry to hear about the issue with hardened resin at the bottom of your Form Wash. You should be able to scrape out most of the residue without concern using IPA to help soften it - but there will always be a bit of cruft left behind, that’s hard to avoid.

If you do wish to purchase a new bucket, please reach out to Support and we can assist with setting up a Wash bucket in your Formlabs cart.

Kind regards,

are you using 99% iso?

similar experience with buying a second hand washer
if you have a Dental Vibrator you can place it on there on the gentle setting with alcohol for a few minutes, but if its really bad maybe 30minutes.
This will help out the stickiness and be easy to flake out using an scraper or x-acto flat Chiseling Blade.

For the mixer, I still haven’t figure out how to remove it but if you apply pressure after a long time sitting in alcohol it might be able to move. If the cured resin is interfering movement and cannot be scraped off, last resort is to file/sand it down starting with the rough/low to highest grit

good luck
