Hello My brand new gle bought in April 2016 - I washed by hand myself almost every week until it was keyed. I made sure the wheels were cleaned almost every weeks and car washed at least three times a month - so no pitting on deep alloys 265 45 20. Since keyed only had washed twice and last time was last weekend - wheels insides are a mess, outside very easy to clean. Therefore, anyone knows of a garage that will take off 4 wheels and just wash and put back on - not want refurb - should 40 quid do it, I guess for a washer with pressure washer ramp and elbow grease takes 40 minutes? No funny comments please.
