Headspace vial dirty

Hello, 

I use HS/GC/FID for quantification of caprylyl glycol in moisturizer. After the run, the cap of the vial is dirty, I find the moisturizer on even if the vial is correctly close.

I don't know how can I clean the oven of the HS. I use a headspace sampler 7697A.

Thanks for your help.
