Floor is 25 years old so over the years spills in front of the fridge, sink & oven resulted in about 50 small etch spots, that they have now covered with rugs, there is one large etch spot in the middle of the room.
Wife said wax was applied about 5 years ago, I am guessing more like 8-10, I was able to scrape the wax out of the grout, kind of flakes off.
There wasn't a pantry or closet where I can test an area unfortunately
Husbands instructions to me was, wife is the boss of the house...do whatever she wants & make her happy.
