Hi Guys, i would recommend using Beyond-kleen safest and most effective glass and mirror cleaner available on the market today, contains no solvents,IPA,ammonia,alcohol, just spray small amount onto a damp little waffle microfiber glass/mirror cloth, proceed to clean lead strips and glass surface, then use a second little waffle cloth dry to polish off for a perfect streak free,lint free,finish. Beyond-kleen leaves behind an invisible protective coating which protects both the lead strips and glass surfaces.
