Nanoskin EVERGREEN x one releases a fine mist of cleaning solution that does not over saturate surfaces. The unique patented "ball bearing" engine creates a high speed rotatable cleaning action with reduced air consumption and noise. The tool can run on minimum 58 PSI compared with previous EG-X001 requiring 90 PSI. You'll see the liquid turning dirty as grime is released from the surface. Wipe with a microfiber towel, then turn the air reverse switch to shut off the liquid source and use the compressed air to dry cleaned area.
