15L Hull Cleaner

What does Instant Hull Cleaner do?
It targets stubborn stains on your boat’s fibreglass hull, helping bring back a cleaner, brighter finish.

Will it remove yellow staining?
Yes. It’s designed to tackle the yellow discolouration that can leave your hull looking dirty, even after washing.

Does it remove rust stains?
Yes. It helps remove rust staining from fibreglass surfaces. It won’t repair the metal causing the rust.

How is it different from normal boat wash?
Boat wash handles everyday cleaning. Instant Hull Cleaner targets stubborn staining that regular washing can leave behind.

How do I use it?
Apply it to the stained area, follow the contact time on the bottle, then rinse thoroughly with fresh water. Always follow the label directions.

Do I need to scrub?
It’s designed for simple spray-on stain removal, reducing the need for heavy scrubbing. Follow the label’s guidance for any stubborn areas.

How long should I leave it on?
Follow the contact time printed on your bottle. Leaving it on longer isn’t a shortcut to better results.

Do I need to rinse it off?
Yes. Rinse the treated area thoroughly with fresh water after use.

Should I clean the whole hull or just the stained areas?
Focus on the areas that need stain removal, following the label directions. Use your regular boat wash for general cleaning.

Can I use it on a jet ski?
It’s suitable for compatible fibreglass surfaces on PWCs. Check your hull material and the product label before applying.

Can I use it on an aluminium boat?
Don’t assume compatibility. Check the label for approval before using it on aluminium or other metals.

Can I use it on paint, decals or wraps?
Check the label and your finish manufacturer’s care instructions first. Fibreglass compatibility doesn’t automatically mean it’s suitable for every coating or decal.

Should I test it first?
Yes. Test a small, inconspicuous area before treating a larger section.

Will it fix a dull or chalky hull?
Stain removal and oxidation correction are different jobs. A dull or chalky finish may need polishing after cleaning.

Will it remove scratches?
No. It cleans stains; it doesn’t repair scratches, chips or damaged gelcoat.

Does it leave a protective coating?
It’s a stain cleaner. Use a suitable marine protection product if you want to add protection after cleaning.

Does it replace my regular boat wash?
No. Keep using your boat wash for routine cleaning and reach for Instant Hull Cleaner when stubborn stains need extra attention.

Can I mix it with other cleaning products?
No. Use it separately and follow the bottle’s directions.
