I use Zep purple degreaser. It's worked fantastic for all my machines. Anything you get you should avoid the fumes anyways.

You will want to pay attention to material safety data sheets. Zep in particular does not require protective equipment except for gloves( which I recommend anyways!). Also has a low rating on flammability (1)

But uh don't inhale anything if you can help it.

Maybe something like rubber u channel trim?
