coldel said:Whilst a car can look clean, it doesn't mean it is properly clean, even with a ceramic coating There is a good article here from the ultimate finish website on how to make the most of the ceramic coating https://www.theultimatefinish.co.uk/car ... intenance/ as it states the breakdown of the coating is accelerated if you do not maintain it as small particles contaminate the coating and degrade it - it does actually recommend a decent particle clean as although the ceramic might push away clearly visible things like water it wont be 100% effective
Wow! Who knew there was so much science (and expenditure) to cleaning a bloody car?

So I'm guessing my Screwfix own brand shampoo and two buckets of warm water is not sufficient? My eyesight ain't as good as it used to be, but they always look really clean to me!
Cleaning cars is like mowing grass...looks good for about a day then you have to do it all over again! I hate mowing grass but love cleaning cars BTW!
