Parts Desk Insights
Best Use Case: Best for quick spot-and-strip hull cleaning when you’re dealing with scumline and rust staining and want a rinse-off result without aggressive scrubbing.
Common Issues: For heavily stained or very dirty areas, plan on a second application and light scrubbing if needed; always rinse thoroughly after cleaning to prevent cleaner residue from remaining on the surface.
