Pressure washing big 6 cladding?

[Wigeon]

I've got some gable ends on grain stores that I'd like to freshen up, as the yard gets used for lots of non-farming things too.

Short of replacing them with new fibre cement, can I pressure wash the old ones? I would imagine dust not an issue in the wet, but am I likely to damage them/ is it basically pointless?

Thanks

Yes but I’d also paint after if mine .

Will it blast particals off it to become dust in the wind later?

It might be useful to experiment with different jets on the pressure washer lance. They are available online. Smaller jet will give you higher pressure, more effective at removing crud but may damage the surface, larger jet will give lower pressure, less likely to cause damage. Try them out on a place that isn't too obvious.
