Thanks David,

I tried cleaning it with a two part, single use (the little foil pack
things, like what you ship with your products) optical cleaning pads from
Calumet Photo.

I got just a small change in the "a" value (went from -1.06 to -1.32 with
the L and b staying about the same).  So I guess I can assume the tile was a
little dirty and it sounds like it is OK now.

Values now are 90.69 ; -1.32 ; -1.56

 

I am not real familiar with the L-a-b values so I thought it best to ask and
make sure I am starting from an appropriate place.
