I've been asked to price up jet washing a multi story car park ceiling, walls but no floors. I'm not sure what sort of price per metre I should be going for.

The building has water and it 6 stories.

I'm very new to pricing up pressure washing, I've only quoted for domestic and light commercial.

The ceiling also has strip lights, how do I get around that with out damaging or killing someone?

You do seem to get some very odd pressure washing requests . If it was me I would give that one a miss as pressure washing and electrics don't mix very well. The last thing I would want is to short out the electrics on a muliti storey car park... Oops! sorry mr its all gone dark for some strange reason 

The bit about they don't want the floors done also made me chuckle as will be soaked anyway with ceiling & wall cleaning runoff if using a normal cold pressure washer.

Agree with smurf,

Something odd here, I can understand the outer walls even inner walls for graffiti removal but just a general clean ??
Best bet is to see if Lee from blast away might talk you through this ( doubtful ) or rob at m-clean ( good chance ) both are unfortunately both no longer on the forum.

I have quoted a car park clean - 5 levels ( 600 spaces ) but that was a newly built one and mainly cleaning off builders dust

I quoted exactly this in Canterbury as they were repainting the walls and ceiling white and they wanted the  dust and cobwebs removed. The lights will be splash proof - ip45 if I remember correctly. You will need a 45 degree nozzle and good waterproofs and it will take longer than you think. 100 cars a floor is a small carpark -price it at 300m a day and you won't go far wrong but confirm what they are wanting to achieve before quoting

Why not do a small test area?  Get their approval and then quote it accordingly!  Simples

Some good ideas here, this is a 'gateway' job to a lot more work, I wish it wasn't so, I would rather not do it lol.

But I will try and quote it anyway.

So, I can use a jet wash on IP45 lighting , correct?

We did a bus station to remove all the flaked paint off the ironworks ready for the painters.
This was completed in 6 nights and had some very clean waterproof overalls ! 
As mentioned , don't under estimate how long this will take. Also determine what is their expectations of clean is because you will have a lot of carbon build up from the cars!  A test patch is vital so all concerned can see the end result .
IP45 can withstand low pressure for a limited amount of time.
IP 46 can withstand high pressure for a limited amount of time
Dont worry about IP47,  IP48 you will need to be under water for these !
