Freezing may work but is something I would consider highly unreliable and risky.
Raising the temperature to 40 °C or above for at least an hour will kill will kill all stages. Of course boiling items to be sterilized will work reliably too.
I usually go to 50 to 60 °C for an hour with items that can't be boiled like pumps that have PVC parts. (I tried boiling a pump once and ruined it :headwally

Small artificial "live" rocks, ceramics and the like get boiled.
I find drying over only 24 hours too insecure with items that have small, deep cavities that might hold moisture for a prolonged time. Unfortunately many pumps fall into that category and also can't be boiled.
Bleach and drying works best for tanks (or plastic containers), PVC tube ends and fittings and similarly smooth and open objects.
For TTM the safest method is to have 4 of everything - one set for each step. That way you don't need to scramble to clean and dry while doing TTM.
