Hi Guys,
Today I treated my Dad and washed & polished his car. I have some alloy wheel cleaner (in a bottle, clear liquid, paint on with a brush. Can't remember the exact name but if important I'll go and find out) which I used to clean his alloys. I used the same bottle of cleaner to do his Volvo before and with good results. However, upon using it on his Mk4 golf (standard alloys that came on it) streaky white marks have appeared in patches. If you rub them with your finger, dry or wet, they disappear and then reappear again after a few seconds. I've rubbed hard with a damp cloth and the same happens. I've rewashed with soapy water only. Still the same and still patched in the same places i.e. its not residue from whatever I'm using last.
The front 2 wheels are worse but all 4 have come out in these patches. I never noticed them when we got the car. The wheels had become pretty dirty before I cleaned them so couldn't have seen the marks prior to this wash if they were there.
I'm totally at a loss with this.
Picture of wheel (ignore the pink circled mark as this is a scuff):
Photoshoped to try and show the patches better
Any ideas/help would be appreciated.
Cheers
Jon
