I come here cap in hand. Not sure that this is the correct place to raise such a query but here is probably as good as any.
I have a problem and looking for advice. How can I clean auto windows inside and outside so as to be not only clean but also streak free? I mean really really clean; as in concourse ten points clean. I have been trying for several months on wife's SUV and my Porsche. I am not really normally obsessed with cleanliness, just look at my office.
This all started when no.2 son, with help of no.1, convinced me to nano ceramic treat exteriors of both cars. They both stay looking so good that I am embarrassed by streaky windows. I have tried to rid the problem with many products and appliers including fresh cotton, fancy cleaning cloths, paper towels and newspaper. I have applied Windex and Ajax products as well as those from ArmourAll and others. Tried filtered water both from the filter and mixed with white vinegar at 10 and 20% mixes.
I go from inside and outside and chase back and forth in any effort. The only thing that seems to get cleaner is my dash boards from over-spray and/or spillage.
Any bright sparks out there with good advice?
With thanks in advance of any support.
Regards
