Update:If by chance you had the problem I did where it left sticky residue behind on the glass. Do not user window cleaner or alcohol unless last resort, something that simply worked for me was this.Take a strip of scotch tape or invisible tape and rub it over the affected area of the glass. Then simply peel the tape away, along comes with the tape the residue. You can then take a plain cloth or tshirt and wipe away any left over oils and you are good to go.
