actually, i didnt clean it... damnit
Even better, test time is up.
Any oil slicks or dead fish?
I don't rinse mine. Can't see the use. If it's clean already, I'm just adding chlorine to the tank (cleaning in sink). If it's dirty, rinsing probably won't get it clean cause it's acting like a filter. It's usually what's called virgin material (all new) unless otherwise stated. I do check to see if it's oily tho (rub a paper towel against it and check the towel for residue, shows upkinda clear.
I do test it if I change brands.
And I am careful not to get opened packages.
The open rolls from the cloth stores are the only concerns.
