Remove overlapping cells between two grids

For example, I have two grids (A and B). I would like to remove from GridA any cells that have a value in GridB.  Grids A and B occupy the same space but measure different things.  What is the best way to perform this operation?  I was not having success googling the issue.

Thank you kindly,
