tackyness

I've looked through threads on this issue any they get confusing as commentators have different definitions of tacky, I've even seen people mention hybrids and rubbers like Secret Flow that aren't really tacky rubbers. For the purposes of this post, Dignics 09c isn't a tacky rubber, I am...

What's the best way to preserve a rubber's tackyness? Thinking Dignics 09c in particular. I know about covering it with the plastic cover (and doing this). I'm more thinking if there is some cleaning product in particular that is good to use?
