Update. Been now told jet washing is a no-no, so now holding off for

You don't want high pressure water as it blows the dust everywhere -
just lots of low pressure water. The ideal device is a watering can

liquid to each can of wate. The washing up liquid acts a s a wetting
agent ensuring the dust doesn't blow about..
