Jizer FTW. Or Gaz says they have these 10 litre barrels of this citrus degreaser stuff at work, that shifts nasty thick oil left over from the printing industry called Boiler Fuel Oil. Unfortunately, that will be hard to sneak out the gates lol.

Fairy Liquid, Bilberry, Snow Foam, Topped up with water.
Worked pretty well
