Remove your stock wiper blades. To remove you need to depress the plastic clip and slide the wiper off.

Take the new PIAA wiper blade and locate the correct size clip included with the wiper that fits the stock wiper arm. On the MINI this should be the smallest clip. Insert the clip into the PIAA wiper.

Install the new wiper in the same manner you used to remove the stock wiper.

Wash your window with soapy water and dry.

Whip your front windshield using the silicone and alcohol wipe included with your wiper.

After 10 minutes buff out with a dry cotton towel.

Dry run your wipers for 5 minutes.
