I bought a bunch of new open box full extension drawer sides with most of them being soft close style from a cabinet shop that is closing down. They were sitting in open shelves and are full of the dirt and dust from not being covered up. Anyone have any suggestions on a good way to clean them up and get them operating smooth again. I thought about soaking them in purple power then applying oil to the ball bearings once they are clean and dry but dont know if that will damage the soft close function.IMG_2116.jpgIMG_2115.jpg
