I have a sander that's not functioning properly, and I initially thought wet sanding would be okay, but it seems to have caused some issues. I tried cleaning it with just water and a brush, but the problem persists. I suspect the switch might be the culprit since it's the last part I haven't taken apart and cleaned. Previously, I had a bad experience using a cleaner on my power tools, which led to the plastic breaking down, so I want to avoid that at all costs. Any advice on safe cleaners for plastic?

For issues like you're describing, if it's electrical, contact cleaner or a degreaser could really help. Just make sure to choose one that's safe for the specific materials in your tool.
I've had good luck using Tub O' Towels for cleaning my tools. They're tough on grime but gentle on plastics, so you might want to give them a shot!
I recommend using orange Simple Green. It works well for cleaning greasy tools and hands, and while I’m not an expert, it hasn't damaged my plastic tool parts. If you think the issue with your sander might be electrical, look for contact cleaners that are safe for plastics—they can really make a difference!
I use Spray 9 for my cleaning. It's effective and shouldn’t damage the plastic. Just be cautious and avoid oversaturating any components!
I've heard good things about Spray 9 too. Just be sure to wipe it off well!

Definitely check on contact cleaner! Just make sure it's specified as safe for plastic.
