Summary

This video covers a full interior and exterior cleaning of the Mini Plus spray machine. Proper daily cleaning reduces overspray buildup, protects components, maintains finish quality, and ensures reliable machine operation.

Quick Guide

  2. Remove gun socks (cut off with scissors).

  3. Vacuum walls and interior surfaces (preferred over blowing dust).

  4. Remove and replace dirt trap material.

  5. Remove side shields carefully (do not drag across belt).

  6. Remove filters and vacuum beneath them as needed.

  7. Clean overspray:

    • Solvent-based coatings → solvent + rags

Exterior Cleaning
