Yep, that might work, but the van's down on the day. Either way you've likely got an irritated customer so lose, lose. 

So what do you do? Just tell them you're incapable of cleaning it, they'll need to do it themselves or get a proper window cleaner?

I certainly wouldn't be attempting to remove fat as described in the op. Limescale we would, paint splashes too, but not concrete for example. If I don't know how long something will take I'm not interested. And I certainly wouldn't go out to have a look.

Go out to have a look? But you're there?? Otherwise how would you know?

Not usually - neither are you.

Never, but I've long since trained all my lads how to price a job.

Well if they've the experience to know how long it will take to remove first floor windows splattered with fat then they're better trained than me. I wouldn't have a clue. It's one of those impossible ones in my experience. The customer thinks you should just do it anyway, but if you quote £30 to do it, they'll just get someone who'll do it for nothing. Plenty around. I find it's easier to say we don't do it. There's no right answer though. Each to their own.

They're certainly better positioned to price that than me.

It's always a bit of a punt with jobs like that sometimes you get it spot on, other times not so much. If they turn you down then fair enough, it's got to be better than "I'm not capable, sorry".

BTW £30 isn't enough. Probably.
