White Glove Test

White gloves being used to test the thoroughness of a cleaning job. If you run your finger across the mantelpiece, shelf, or back of a chair and it comes back clean, you know a good job was done. Truth in Television (the basic motion, with or without the gloves).

 * In Carole Nelson Douglas' Spider Dance, Sherlock Holmes is asked to investigate a matter in the home of William Kissam Vanderbilt. Holmes comments on the cleanliness of the house (he's actually chagrined that so much evidence is lost), and it is noted that Mrs. Vanderbilt tests the cleaning staff's efforts this way and fires those who fail.
 * Roald Dahl wrote about a prefect at his Boarding School of Horrors who would do this after having his fags clean his study.
