Recently I had to clean up the bottom of the tank from a failed print. In the past using a metal scraper I have done some damage to the soft bottom layer and wanted to be careful as it was a large failed print.
So, I took a plastic scraper sold as part of a kit for cleaning glass stove tops and tried that.
It is softer than metal and lacks the sharp edges but it still gets the bottom neatly clean - much easier to use than a paint scraper type tool.
The one I used was from Weiser and is sold as part of the glass stove top cleaning kit. It’s nice to work with so I thought I’d share.
