Special clear caulk for granite counter seam thats frequently wet??
 

I have a granite countertop that constantly develops problems in the
seam behind the faucet where thebacksplash and counter are seamed.
Because it is virtually impossible to keep this area always dry, the
silicone clear caulk I use to maintain this seam always degrades in a
few months softens and peels off.
Is there a type of clear caulk that can hold up for this common
problem??
Thanks for your help!
