I have just paid a local leather speciaist £300 for a 2 day course in how to clean leather.
My wife has just informed me that for the last 15 years she has cleaned ours with fairy liquid and warm soapy water.
I have had to admit that it looks as good as new and the leather is really soft and looks great.
Please tell the dope that she is wrong and my money was well spent !!!!!!!!!!!!
