"I have been using Ecoworks Marine products since their launch and I'm still impressed to this day. I think it's an ingenious concept and paths the way for the future of bio products. I mostly use the eco degreaser in my engine room which works better than any other product I have used. The 'FOG Buster' is excellent and with periodic use has led to a greatly reduced maintenance on associated lift pumps and sani-splits. Keep up the good work!"

Dominic Ratty, Engineer, MY Oneness
