This is psychology in action
I wouldn't worry too much at this stage.
Yes, mirrors should be cleaned with slowly running water only and then washed with distilled water to remove any traces of minerals that are normally dissolved in tap water...
But even if you can see the damage on the mirror itself, the effect on image is minimal - unless you have many paralles streaks - this will result in quite ugly difraction artefacts on bright objects.
Couple of years ago my 10" dobson OTA slipped from my hands (morning dew) and ended on a concrete floor. Secondary was broken into pieces and fell on a primary... I was devastated then but after washing the mirror, I can see only a thin circular track where secondarry impacted the primary, but no effect on image whatsoever. The telescope (with new secondary) is perfectly usable.
So don't worry... just give it a proper wash.
If this doesn't help (which I think it will) then contact Mr Suching - for recoating job
