Plasticizing suction cups

[Johnny Reefer]

Boiling them in FW sometimes works. But then...sometimes not. I agree that buying new ones is a good option. That's what I used to do....until I set things up so I don't need the damn things anymore.

Cheers,

You could try silicone lubricant but to be honest I doubt if it will bring brittle suction cups back.

I use it for the O-Seals for my UV Sterilizer. The UV really does a number on the rubber but the silicone lubricant really extends the life.

You will probably have better luck starting with fresh suction cups and treating them while they are new and reapplying when you perfrom your regular maintenenace.
