Maintenance & Best Practices

Routine Cleaning: Wipe down the textured PEI surface before and after prints using Isopropyl Alcohol (IPA) and a fresh paper towel. Avoid using acetone, as it will permanently damage the PEI coating.

Deep Cleaning & Restoration: If bed adhesion decreases over time, wash the plate using mild dish soap and warm water to remove grease and filament residues. For persistent oils, lightly scuff the surface with 600-grit wet/dry sandpaper, then clean thoroughly with IPA.
