Depends on what I’m cleaning for. Countertop? Just a basic surfectant and done. Bathroom? Diluted Bleach. Aerospace equipment? Assuming CRES, I’m first running the item through an ultrasonic cleaner with a mild detergent, then ultrasonically cleaning again with DI water, then passivating per AMS2700, Method 2 in a FOD protected area or low-grade clean room.

To quote an old teacher: “there hasn’t been a counter so dirty a little benzene can’t clean it!”

I’ve never used one myself, but autoclaves are a thing nobody’s mentioned yet.

Edit: it occurs to me that I have used one before, if sterilizing food with a pressure canner counts.

I had access to a laminar flow hood at work, so I cleaned the dust off my phone and installed a new screen protector inside it. That was the best screen protector installation I ever did. Being able to ensure you’ve removed 100% of particles from the screen really makes a difference haha

You use a solvent that is stronger than what you want to remove, but not so strong that it also removes the thing you’re trying to clean.
