Used the Koblenz to do under the 'fridge today and it did a pretty respectable job... it didn't get extremely close the the edges, but I didn't expect it to... that's that a toothbrush and a magic eraser are for 
)
That yellow stuff around the edges is some kind of adhesive that has been there since I moved in... I think it is glue from when they put the tile down or something... nothing has ever gotten it up, but I wonder if the Haan Steamer might soften it somehow if I leave it in one place for an hour and then scrub with a brillo pad )
