     * Never use IPA on the acrylic tank window (it will cause cracks).
     * If dust, fingerprints, and/or contamination are present, clean the clear acrylic tank window with NOVUS No. 1 and a clean microfiber cloth. The clear acrylic tank window is located on the underside of the resin tank. Apply 1-2 full sprays of NOVUS No. 1, and wipe using long, sweeping strokes top to bottom and across the tank window. Fold the microfiber cloth after each swipe to prevent dust and debris from scratching the acrylic.
