It does not affect the actual game for an advantage on paper (though it could be a roleplay advantage -- which I'm good with) so I wouldn't worry. That does not make me right, or moreso than your current DM but I wanted to share why I'd tweak it some.

I agree. Anything creative and quirky that a player wants to associate with their character (as long as it isn't more statiscially advantageous than the spell is supposed to be) is encouraged by me. Cev, my 3e gnome character got Prestidigitation 1/day and it was one of his least powerful but most fun spells. He used it for something or another almost everyday.
As an interesting aside, the D&D 3.5e SRD (yes, I know it's 3.5e and not 4e but hear me out) explicitly states the following in the spell description for Prestidigitation:
Any actual change to an object
(beyond just moving, cleaning, or soiling it) persists only 1 hour.
So, according to 3.5e at least, the spell can legitimately and permanently clean something and not simply make it "appear" to be clean. Use or ignore that at your own discretion. As always, everything is subject to Rule 0.
