Second snarky post from you. It was a sincere question.
What's with the attitude? Did I do something to offend you? I just suggested another alternative to baking them. Not everyone has access to a stove (hotel, camping, hot plate apts) or may not want to heat up the stove for a few cartridges.
Spinning works great and you can use them immediately if you want.
The reverse taryn spin is a well-known method here to remove excess liquid from cartos. You can read about it or watch YouTube videos showing how it's done by searching at Google for "taryn." Searching Google is the best resource to search for anything here on ECF -- and will lead you back here.
No attitude here and no snarkiness intended...just trying to help you learn, since you're new at this, about the preferred method of removing liquid from cartos. But to dry cartos completely, using an oven is the best choice. Of course, one needs to have access to an oven for 10 minutes in order to do that. Otherwise, you could place the rubberbanded cartos in something (like a sock) and place the sock in a dryer for a few minutes, like when drying towels or something similar.
You should always dry cartos thoroughly after cleaning them. StormFinch and Salemgold brought up very good points about why you should dry them completely before adding e-liquid. I also mentioned above another effect that can occur if you refill cartos when the filler inside is still damp, moist, and/or soggy.
I've posted many times, in other threads and in this thread, that cartos shouldn't be cleaned -- and the reasons why they shouldn't be cleaned. The important point is, if you do clean them, they should be completely dry before filling them with e-liquid. Spinning them doesn't get the fillers inside completely dry. Letting them air dry or using a fan takes too long. Using an oven is just right.
