I recently conducted an experiment testing the effectiveness of ninhydrin and dfo on porous surfaces that had been submerged in water. Any articles that deal with this type of experiment out there anywhere?

From my days as a barman I remember that lipstick on the rims of ladies wine glasses quite often make it through the dishwasher.
Could you change your storyline to make it a lip print? These are also unique and can be identified under the right circumstances.
If not, a fingerprint made with some waxy deposit (on the top shelf, upside down :)) and perhaps with the operator forgetting to put in the detergent might not be too unlikely.

PS It is good to know some writers do research their storylines to make sure they are realistic. Some of the things I read and see on TV are just ridiculous.

Melinda,

I'm sure several people who have read this have immediately thought "anything is possible." Perhaps... but likely? Hmmmm. no. But the least unlikely possibility (ha ha) might involve a greasy print on the bottom of a drinking glass on the top shelf (since the glass is upside-down and as far from the water stream as possible.) It would also help if it wasn't a whirlpool. :)

Why not have the dishes washed by hand with that spot being missed? just a thought.

Hi, I'm a writer with a question. If a glass with fingerprints on it was run through the dishwasher, would it still be possible to retrieve prints?

If not, is there a surface other than glass that could make it through a dishwasher and still possibly have a fingerprint on it?

Thanks!
