I just use morrisons window cleaner. cheap and it does the job.
am I missing out on anything better?
When it comes to windows, a cleaner is a cleaner really.
I prefer to do a deep cleanse with say Werkstat Prime Strong, inside and out, and not only does this do a supreme job of cleaning the glass it lays a layer of sealant on them so that I only really have to use a microfibre on them. While driving in the rain, the rain just beads off the windows superbly. On the outside windows, I repeat this only about 4 times a year. Inside, only twice a year.
Does it matter that you use prime on the insides? I use Werkstatt.
Is this not hazardous? If not I am going to try it on the inside this week.
Can you put WAX on the outside of the windows?
