Buying Guide

Match cleaner to surface

Choose products formulated for the material you’re treating—vinyl, teak, fiberglass, metal, or neoprene—to avoid damage and get better results

Prioritize biodegradable formulas

Biodegradable and phosphate-free cleaners reduce environmental impact and are often required for use in marinas and environmentally sensitive waters

Select concentrated vs ready-to-use

Concentrates offer more uses per bottle and compact storage, while ready-to-use options save prep time for quick spot cleaning

Look for specialty functions

Descalers, hull stain removers, teak sealers, and wetsuit-safe cleaners address specific problems better than a single all-purpose product

Check compatibility with marine fabrics

For upholstery and wetsuits, pick cleaners labeled safe for vinyl, leather, or neoprene to maintain texture and avoid shrinking or discoloration
