I picked up a conservatory roof clean last month because their usual cleaner refused to go up a ladder. Also quoted the house whilst I was there. They are booked in for the consevatory again tomorrow but not the house 'cos they still have their usual cleaner! Custy wants the inside of the conservatory done by me. I've never done an inside before how do you recommend I do it. Obviously not wfp!

I did one and for the inside roof I just used a spray bottle with a scrim to,polish and buff it up. Took some time but if the price is right you should be ok.
For the sides I just laid scrim at the bottom on the window board and mopped and bladed it. Cust was fine with this

If your going to trad the windows on the inside just hold your mop underneath the blade, moving it back and forth across the window as you go, catching the drips off the blade, holding the mop horizontally.

or if you're really good you'll double hand (that is, apply and squeegee at the same time) working with the applicator below the squeegee just as xxmattyxx says), much faster, neater and less effort.

I've used both these methods to good effect.
 
Also, twice in thirty years I've found myself cleaning a property only to discover that the custy had another window cleaner as well as me cleaning their windows in between my visits. On one occasion a nieghbour to one of the said custies told me the other window cleaner had turned up the day after I cleaned them. Never a word was spoken to me by the custy concerned and I never got to the bottom of why, but hey, as long as they were happy and paid me, I did the job.
