Mike can’t tell you this because the Degreaser suggests using it outside and officially you have to follow those directions. (Some people have used it inside with good venting. Make sure your venting setup is adequate.)
Don’t hang around and sniff it.
Or you can do this…which is what i do…haven’t had to use the degreaser yet (3 years)…
Going to be a lot easier to do on a non-Pro model machine.
