Fast and effective hull cleaning, no heavy scrubbing

STAR BRITE Instant Hull Cleaner targets waterline stains, yellowing, scum lines, and rust marks on fiberglass, plastic, and painted boat surfaces. With a simple wipe on, wait a moment, then rinse off, you can reveal a brighter, more even finish in minutes. The formula is designed for marine use, balancing cleaning power with user friendliness so you can tackle routine maintenance without wrestling with stubborn grime.

You may notice a fresh scent as you work, and the product often leaves a clean, refreshed feel after rinsing.
