Hi,
I have an oral syringe that I frequently use to measure out dosages of
oral suspensions but lately the plunger has gotten very sticky and hard
to use. What should I use to lubricate it that won't contaminate the
medicine or eat away at the rubber? I plan on getting a new one but
until then any suggestions? I've tried things like butter and vegetable
oil but they are barely good for one use.

Thanks
