Mack Ocean Potion Multisurface Cleaner BioFlask 500ml This cool critter is all about the hard surfaces – mirrors, glass, metal, tiles, hard plastics that are ‘people marked’. It goes in hard with the big-hitting clean, then carries on working while you put your feet up. Grab your clean 500ml or 750ml reused or repurposed trigger bottle, squirt a measured amount into your bottle and shake. Slap on your pre supplied label and when the going gets tough, spray so that the tough gets going. Don’t have an old trigger spray bottle? try one of our reusable cleaning spray bottles.

Get your lab coat with lots of pens in the top pocket. The initial clean is mainly done by fermentation extracts, enzymes and green surfactants. Fermentation extracts are produced by bacteria and added into our products to give that immediate cleaning action. Our highly biodegradable actives instantly lift dirt, oil or grease and grime from the surfaces. Simultaneously, our lab made fermentation extracts break down dirt and grime making them even easier to dissolve in water. Finally, our natural bacteria digest the newly dissolved grime, which eliminates residual odours and they continue cleaning days after the initial clean. We call them ‘a million little helpers’.
