How to soak multiple orchids?

[DesignerofBeauty]

Hello All!

I have seven potted orchids and two mounted orchids. I'm planning on transitioning to the soaking method of watering instead of using my faucet sprayer.

I'm wondering how to do this in a manner that prevents diseases. I understand letting three orchids soak in the sink, using the same bath of water is a bad idea. So therefore, I'll need to soak the orchids one at a time. After I've soaked one orchid, can I just let the water drain down the sink? Then, fill it up again for the other orchid? OR do I need to disinfect the sink with Lysol? Or, would Physan 20 work better (which, according to the label seems to be quite dangerous to use. It could be just to protect their liability, however.)
