There are numerous enzyme based paste removers available at most DIY stores, at least here in the U.S., but I've had just as good fortune from 1/2 Cup of dish detergent, 1/2 Cup of liquid fabric softener and a five gallon pail of warm water. Be sure to have a standby five gallon pail of clean warm water to rinse thoroughly. In addition I use Scotchbrite pads and lots of elbow grease... Best of luck!
