Interesting tip if your Aeropress is slipping, to expand the plunger's rubber while contracting the tube. Maybe I'm just not an adequate Aeropress user, but mine shows no slippage at all. And I'm almost through my third pack of filter papers.
I've had my aeropress for years. No slippages. Perhaps washing the oils off would help.
