salt corrosion - how do you deal with it?

[frozen]

had my car out a few times over winter last few years and notice some discolouration on the aluminium suspension parts - that's fine and as normal given it's age and use. But this year notice some crystals on the end of the rear suspension lower arm which I can reach through the wheel and wipe off with my finger quite easily - feels like salt corrosion build up maybe?

So I can pressure wash it which is the usual thing I would do - but wondering if there's a better way to deal with it that anyone else knows?

(Not driving on salted roads is pretty much impossible so am looking to manage it rather than avoid it).

Drive it next time there's a downpour? When I got mine there were little salty marks on the calipers. I know the previous owner drove it in all weathers.

I don't drive on salty roads - not because I worry about bodywork corrosion but because I don't want all the nuts and bolts seizing.

Other than that jet wash underneath.
