I disagree with you on the aroma 100%!It is some nasty stuff...but it does work!
I like the smell of Hopps #9, it brings back fond memories as a kid.
I used either Slip 2000 degreaser/cleaner or another water soluble cleaner. There are a few good ones on the market. You can mix one up with water and Simple Green too... they have no smell, clean up nicely and don't cause cancer. I switched over years ago, thought I would hate it but now its all I use.
