I have the original Prusa i3m3 printer. Prusa recommends cleaning the bed before each print with isopropanol (isopropyl alcohol), with only occasional cleaning with acetone. The textured bed prohibits using acetone.
Given the SARS-COV-2 situation and COVID-19, isopropanol is impossible to find, and will not be in stock on shelves in the US for months.
What would you suggest as an alternative that might still be found on store shelves?
