If the photo paper is stored for many years, it becomes dirty with dust, and even if it is not stored in a dry place, the moisture will stain the photo. To restore the clarity of your photo, all you need to do is follow these steps.
What do you need?
How are you going to proceed
Firstly, if your photo has mushrooms in it, you will need to put on latex gloves as you can get them. If they are not there, then there is no need to use the gloves.
Fill the container with half of the water and alcohol, put the photo in it and gently rub the cotton on to remove the stains. It is important that you do this only within the first 5 minutes If you rub the photo for longer than this time after dipping it, the photo emulsion that the image is printed on may peel off or peel off the paper. Leave the photo underwater for another 15 minutes and let it dry naturally.
Remember to always save your photos in a photo album as they are the best option against moisture.
