Well it was how it was said, that it should "cleansed" away. Almost like it is a "dirty word" that must be "washed". I don't see how you can "cleanse" the name of God, in fact I found the remark Blasphemic.
Not all of us here have English as their native language.
I just couldn't come up with more suitable expression and didn't want to spend rest of the day browsing dictionaries.
