Marine 16 ZERO Engine and Bilge Cleaner 750ml

Zer0 Engine & Bilge Cleaner is a gentle but effective product for cleaning all exterior engine surfaces and bilge areas of your craft.

But how can a product used to clean oil be biodegradable?? An obvious question:

....Firstly, as it cleans the oil and hydrocarbon pollutants it does not add to the overall pollutant as a solvent would.

.…Secondly if left long enough it would eventually effectively breakdown the hydrocarbons using specific bacteria and enzymes known to eat hydrocarbon.
 
This is a truly biodegradable product manufactured specifically for the marine industry.
