We reckon there is no such thing as a light duty bilge clean unless you are abnormally anal. If you are, you won't need this! If like most of us you have been a bit slack in this department, this is your product.

You pour it in the bilge, add some water and leave it for a while. Make sure you pump out the dirty water thoughtfully, preferably in an authorised pump out facility.

• Caution! Like all good stuff, it is a little bit bad.
• It contains Z-Propanol and Dipropythene Glycol Methyl Ether.
• If you are allergic to any of this, don't come near it.
• Made in the USA.
