Can anyone tell me how to get the black plastic out of the portafilter without damaging it. Ive a 3 yr extended warranty on it so dont want to put myself in a position of not being able to make a claim if required.
Ive heard that removing this helps with the cleaning process (so bugs dont grow in between the metal and the plastic) as well as helping with the extraction process (or do I need different baskets as well)
Any thoughts

Cheers
