I have a Volkswagen Golf and have a problem which has been ongoing for the past few weeks with a steering wheel that becomes sticky after about 20 minutes of driving. It is nothing to do with me gripping the wheel as I have been driving for 48 years. Any suggestions as I have tried water, Halfords matt cleaning wipes and also paper and a tiny amount of washing up liquid, all to no avail. crawfordhamilton@gmail.com
