I think the only way TLC can have a negative effect is A. You stir the sandbed up and release a bunch of crap in the water and crash it or B. You start dosing things into the tank that aren't needed and cause more issues.
Plus, if there's no fish in there, I'd be even less concerned. Scrape the glass, start doing water changes, get a good CuC when the parameters are good and the tank can only improve.
