There are two latches at the bottom corner that latch tightly but are easily unlatched so that you can clean the window underneath. I have done this several times. The louvers are held on with 3M tape that won't come off without a fight. Believe me I know. I was originally sent the wrong hardware kit (I bought from a guy on ebay) and hence installed it in the wrong place. It took me a couple of HOURS to remove the brackets without cracking the windows and also clean the residual adhesive off. Follow 3M's instructions for proper adhesion.
