You can use denatured alcohol to clean it. You will need a urethane sealant to properly install it. You can buy the sealant in caulk tubes at most auto parts stores.

Wear rubber gloves when working with the urethane as it will get on your skin and is very hard to remove. If you get some on the car's body, use denatured alcohol on a paper towel to clean it off before it cures.
