How to Clean Black and White Photos

Place a clean towel on a flat surface; choose a surface in an area without excess dust, such as a table in a clean kitchen.

Put on cloth gloves before handling the photos. Place the photos face up on the towel.

Spray each photo with the compressed air to remove any loose dirt. Hold the corner of each photo while spraying the air to avoid having the photo come off the towel.

Wet a lint-free cloth with emulsion cleaner. Do not saturate the cloth; excess solution may damage photos.

Use light to medium pressure to wipe the dampened cloth over each of the photos. Make sure to cover the entire surface with the solution. Allow the solution to evaporate. Repeat the process if the photo has not come clean. Place the photos in an acid-free photo album and store in a dry place.
