Cleaning Dirty Ceiling

[rockingrodders]

I have a large artexed ceiling to paint, that is very dirty, mainly black dust, blown in from the tarmac crusher next door. I have vacuumed as much as I can. I know it should be sugar soaped and clean water washed but the area 9m x 4.5m is a bit daunting and arm aching.
Is there any other way of preparing it for a new coat of paint?

use a broom & soapy water?

Use one of those squeezy foam mop things using sugar soap and let it dry before painting.

Thanks for that lads. So its a broom and a souwester for me I think

Used an extendable car wash brush, didn't need the souwester. Magic job, quick and easy, good results. Thanks for the suggestion,
