Visible Duct Labels and Layout Marks Remain at Turnover

Fast answer

Remove temporary stickers, shipping labels, marker notes, tape residue, and layout marks using the approved cleaning method, while preserving required system identification and finish.

What to check

1. Separate permanent labels from temporary marks.
2. Test the cleaning method in an inconspicuous area.
3. Inspect from normal occupied sight lines.
4. Photograph finish damage that cannot be cleaned.

Do not

Do not use solvents or abrasives that dull, stain, or remove a factory finish.

Ask the foreman

“The exposed run still has shop stickers and layout marks visible from the floor. Which labels are permanent, and what approved cleaner should we use on this finish?”

Why it matters

Temporary markings that seem minor from the lift can dominate the appearance of exposed architectural duct.
