Hi Gareth
The vehicle was always washed by myself as its a new vehicle, the products used were Audi wheel cleaner and shampoo etc. (I am so glad I used these products as purchased in the dealership)
I actually have a water softener installed in my home, so the water is silky soft which is 100% better than hard water. Don't use the Pressure Washer as I have a new Motorhome and have to be very vigilant when cleaning, and usually wash the two vehicles on the same day.
Text book Gareth, that's the concern. Most drivers dont actually wash their own vehicles by hand and therefore dont get up close and personal with their vehicles until its glaringly obvious any issues or concerns with bodywork/chassis/alloys etc.
If you want or need the other images please dont hesitate to ask. They look like very small blisters to the naked eye, but its actually water ingress under the lacquer, people could mistake them for lacquer or paint anomalies until they get really bad...
