Speaker Grill Cloth, On or Off

I was wondering how many members use their speakers with grill cloth removed? I realize that speakers may have been voiced/designed by manufaturer with cloth in place, but this is just another variable that effects sound. I do it both ways and seem to get slightly more detail with cloth removed. I also wondered if dust becomes a problem with cloth removed, especially in tweeter.

Probably any home with children will have cloth in place, just too tempting to touch that shiny tweeter dome.
Anyway what are members approaches to this.
