Thanks for your good wishes chaps
It went pretty well it was a kitchen and dining room , it was a mate of a mate so the conversation was pretty relaxed. The customer was happy and has said they will recommend me

One thing troubled me a little, because of my lack of oragnisation and my broken foot i had not got round to buying my ultimate master.
At my local cleaning supplier the nearset i could find was
Chemspec one clean powder and
chemspec trafic lane cleaner.I was not that impressed with the result it did not feel like it was cutting up the muck as well as ultimate master.
The dilution for the pre spray was 1 part to 10 water.
I wondered if any of you chaps have used this stuff and had any advice i used it with 40c ish on the rinse solution temperature and the pre spray cold.
I am ordering my ultmate but as this stuff seems pretty safe i would like to use it up on cleans.
