Resetting Carrier Selection for all products at once

[patuga]

Hi,

i've recently installed a module called "product carrier" that allows me to select which carrier i want to use for each product. but the problem is, i need to remove the carrier selection for each product so they are all available again, then the module will apply it's restrictions.

 

So i'd like to know how to reset the carrier selection for all products instead of having to go manually to all of them, which would defeat the purpose of having the module installed in the first place.
