Dreumex 10527001008 Hand Cleaning Paste 2.7 kg

I first used this a few years ago at a bike shop and was very impressed, its not the cheapest but its worth the cost, the tub is quite large so the wife doesn't like it sitting on the kitchen counter but you get a lot for your money. It starts off with a bit of abrasive and then as you add more water it turns more soapy, its probably the best stuff I have used for shifting oil and grease etc.
