How do I go about washing 28ft walls in a factory? Is there any type of equipment that would work best?

With a toothbrush silly!How do I go about washing 28ft walls in a factory? Is there any type of equipment that would work best?
Scaffolding, a Saftey belt, and a pressure washer.





Um...To use a pressure washer on a ladder sounds more like something Wile E. Coyote would do.





Don't hold a high pressure jet of water off of a rickety ladder, even firemen don't do that, the hose is attatched to a ladder which is anchored to a 20 ton truck.How do I go about washing 28ft walls in a factory? Is there any type of equipment that would work best?
If it is a large factory, you should use a 'cherry picker' mobile work platform and a pressure washer. This is easier than ladders or scaffolding
I vote for the pressure washer and ladder. Be sure not to touch the water under pressure. I did that once and sliced my finger open.
An alternative to the pressure washer is a grit blaster, though it makes terrible noise and can be pretty messy.
all you need is a ladder and a pressure washer


both pretty cheap or available for rent at a local rental store
im thinking a ladder for sure
