How do I clean stainless steel appliances?

A little baby oil on a microfiber cloth will shine them right up.

I use Windex with a soft t-shirt.

I invested in a high end microfiber cloth a few years ago, SuperCloth. I use them for my screens, windows, and appliances for a streak free clean with just water. They were under $40 for 4 of them and I feel like they were well worth it because I don't have to use products.

You need to use a damp cloth rather than one that is soaking wet and then immediately wipe again with a dry cloth.

It’s the cloth and a clean surface that make the difference. Even a micro drop of soap or water can make a streak. By drying the appliances with soft paper towels or cloth, you are removing every bit of liquid and buffing the surfaces shiny. Best wishes!
