Skills don't disappear, you can't unlearn something. They lessen in effectiveness if you don't work on them or use them for a period of time, but without physical or mental impairment through injury or illness, then you will always remember how to do a skillet.
I went on a skateboard for the first time in 3 years recently and was still able to do all the tricks I used to be able to do. I haven't ridden a bike in a about 6 years but I'm pretty confident I can go back onto one and ride it.
Maybe you mean to unlearn something you've mastered. You will never forget something that is second nature already. But try learning a language for 6 months and then stop for 2 years and see where it ends up.
