Wash to reveal the paint

A maintenance wash aims to clean a protected vehicle. A pre-coating wash also prepares for inspection and further surface treatment. Separate wheel equipment from paint equipment, remove loose abrasive dirt first and use a shampoo suitable for the planned preparation process.

Avoid adding waxes or gloss-enhancing wash products unless the coating system specifically calls for them. Residue can make later inspection and final surface preparation harder.

Clean methodically

Work on manageable areas and do not let cleaning solution dry. Rinse seams, badges and panel gaps where detergent may remain. Use clean contact tools and inspect them during the wash; visibly dirty equipment should be rinsed or replaced before touching another area.

After drying, identify bonded contamination. Do not automatically use clay, strong degreaser or repeated chemical treatments across every panel. The wash should help determine which of those steps, if any, is appropriate.

Check the transition to preparation

Look for runoff from mirrors, trim and handles. Confirm that wheels and lower sections have not transferred dirt to the paint towels. Document defects now visible under clean conditions. A careful first wash saves time later by distinguishing contamination from damage and giving the correction process a reliable starting point.
