Buying Guide

What type of cleaner should I choose for aluminium hulls?

For aluminium hulls, look for non-abrasive formulas that are safe for metal surfaces. Oxalic acid-based cleaners offer effective stain removal with relatively mild handling requirements. Gel formulas help with vertical sections, while splash-on solutions work well for general cleaning.

Should I use a cleaner with a gel or a spray?

Gel cleaners cling to vertical surfaces longer, making them ideal for hulls and scum lines. Spray or wipe-on formulas are best for large, horizontal areas and quick touch-ups. Choose based on hull area and staining intensity.

Is a complete cleaning kit worth it?

For frequent boat cleaning, a kit with brushes, mops, towels, and sponges can save time and ensure you have the right tools. Kits are especially useful for multi-step cleaning that includes scrubbing and drying.

What about abrasive scrubbers?

Abrasive scrubbers can scratch gel coat or painted surfaces. For aluminium and gel coat, prefer non-abrasive options like sponge erasers or soft scrubbing mitts. Always test a small area first if unsure.

How do I avoid damage while cleaning?

Rinse surfaces frequently to remove loosened debris, use non-abrasive tools, and avoid aggressive scrubbing on delicate areas. Follow label directions for any chemical cleaners and wear gloves as needed.
