Use disposable gloves, line your work surface with a vinyl shower curtain and have drop sheets on the ground to keep clean up simple. Do not pour leftover epoxy resin down the drain! Instead, wipe out all containers and wipe down reusable plastic tools with paper towel. Wipe down once more with rubbing alcohol or acetone to remove any residue. Next, wash with hot soapy water if desired. Or, simply allow any remaining residue to simply cure right on plastic tools and peel it off the next day once it has dried.
