I'm using a standard Luer lock syringe I got from WL. Is there a better solution? Seems like it's only the pineapple tfa that kills the rubber piece. All other fruit flavors are ok.
ETA: I clean them right after using every time. Also have tried soaking it in soapy water overnight. Still going through them...
