My screen material is dirty
Many small areas such as streaks or smudges can be carefully cleaned with a mild detergent (soap) diluted to 30% to 40% with water and applied with a soft, non-abrasive cloth or a gentle brush (e.g. a soft toothbrush). Be sure not to scrub too hard in one spot since this may cause the material to wear out in that spot. Mr. Clean magic erasers works wonders on the screen material.
If all else fails, Isopropyl Alcohol in just a small dab can take off just about any spot.
A lint roller is recommended when cleaning the black velvet frame.
