Parts Desk Insights
Best Use Case: A fast, low-effort hull wash for routine tackle of scumlines and rust staining on fiberglass, metal, and painted areas—especially when you want a spray-on cleaner that doesn’t require heavy scrubbing.
Common Issues: If staining is heavy, you may need a second application and light scrubbing after the dwell time. After cleaning, rinse thoroughly to remove residue and help prepare the surface for any follow-up shine/protection step you use.
