I found this stuff at Lowe's called Krud Kutter.....it is amazing....it melts durt & grime off of everything I spray it on.....it was mostly for sticky things, but I sprayed in on the walls in my kitchen (the previous owners were smokers)......the yellow crud just runs down the wall as I am trying to wipe it up.......it leaves everything it touches clean without eating it up & leaving a hole.

I have also used it on the wood cabinets in the kitchen...the greasey fingers & that cleanes that up completely right before your eyes.

I have also used it on the doggie oops spots on my carpets.....it works wonders on that also.

I have actually never found anything quite this good anywhere....I am sure I will find something it doesn't work on....but so far so good.
