Funny you mention that. Years ago Rick's brother was kind enough to let us use a condo he owned in FL for a vacation.
Before we left, we made sure the condo was clean and everything was as his brother had left it. In appreciation, we left him some chocolate and gift certificates for local restaurants. His brother called to thanks us and to let us know we had left the condo in great shape, except for the dust on top of the refrigerator. I at him and told him whatever dust was up there was there before I got there and I couldn't see it.

He was kidding of course and asked if we would use his condo again sometime as we did such a good job cleaning the place after staying there.

 

Put a coat of Klasse all-in-one. It will keep it clean.
