How patronising, and how inaccurate!
I've valeted for various people all over the country.
I've also done cars at the Motor Show at the NEC, to a standard far higher than anyone on here I guarantee it, using techniques and matierials you wouldn't even have heard of.
They only pick the best technicians.
I've acheived the highest standard qualification from Autoglym themselves.
So yes, I do know what I'm talking about.
Neither patronising nor condescending, merely accurate. Are you saying that you did not work as a car valeter for a garage? My genuine apologies if I've got that wrong.
And I rather doubt you would be considered one the best technicians in the country either! Talk about blowing your own trumpet, if your level of expertise is so great, what an earth did you come into window cleaning for??
If people from all over the country were after your services you could surely have commanded a far better income than you could have done by starting window cleaning!
A patronising reply would be to say that this is the job they give school leavers they can't trust to do anything else...and I didn't say that did I?
You have been what...9 years a window cleaner? Your field of expertise is far greater there than in car valeting I'm sure, and even there you create no end of controversy with your opinions.
And I was not arguing with you on car valeting in general, merely your assumption that pure water is going to affect the paintwork of a car, and where do you get the idea that pure water is aggressive? What accurate research have you read on the subject?
In fact it is probably far less aggressive than some rain (acid rain and so on).
I was no less accurate in the other things I said, trap grit between sponge and brush, regardless of what you add to the water and you will potentially mark the paintwork.
