Too wet of substrate?

So I'm looking to change my girl from aspen over to eco-earth. I've had her for about 3 months now, and she has been eating and shedding like a champ. My main concern is I don't want to cause scale rot. The eco-earth was drenched, but has now started to dry out. No moisture comes out when you squeeze it hard enough, but it's still moist enough to mildly clump together. When do you know when it's right to use?

I toss mine in the oven at 350F for 20 minutes at a time until it's not soaked. It's easier to add moisture to ecoearth than to take it away. It takes anywhere from 1 to 3 rounds in the oven before it's slightly damp, but not wet. Then I rely on their hygrometers to let me know when they need some water added. I like to keep my humidity around 60%.

Scale rot is not a problem until bacteria is present. Usually in form of urine/urates, feces, regurge. Basically an unkept cage.
The addition of water just offers a better medium for the bacteria to multiply with the combination of ingredients mentioned.

If no moisture can be squeezed, it shouldn't take too long reach the proper consistency with more ventilation and even add a fan if needed.
