When I did the TTM with two tanks, just cleaned off with fresh water and let it dry for over 24 hours.

yes 24 hours dry suppose for sterilization. could run with fresh for few days after if wanted to.
rocks is kinda a different thing. completly dry for 24 hours yes, but that's tough to determine. i let mine sit out for about 6 days then running in fresh for over a week.

let them sit as long as you can then run them in fresh.

ok sound good
ill remove the rocks and dry the tank for a week
then i will return the rocks back and run the tank with fresh water for another week
then start cycle
hope it will work

Letting the tank and all equipment fully dry is sufficient. Not sure why you'd want to have rock in a QT tank though?
