When you think of art that is worth saving from mildew, you might only think of paintings hanging in a museum or those that costs hundreds or even thousands of dollars. However, you might have art in your home that's also worth saving. You could easily have art that's worth money, or it might be valuable for sentimental reasons. Sometimes, a painting that you just like might have potential damage from mildew. Luckily, there is a way to remove the mildew stains and save the art.
Touch the mildew lightly with a cotton ball. If any comes off, then place the art in the sun or under a heat lamp to dry it out.
Brush off any surface mildew with a sawdust brush. Work carefully so as to not damage the art beneath the mildew.
Spray a commercial germicide product onto a clean cotton ball.
Dab the mildew stains on the art gently. This will lift the mildew and transfer it from the art to the cotton ball. Do not try to wipe the mildew. It will spread the mildew around and could ruin the art.
Continue adding germicide to more cotton balls and dabbing the art carefully until you can no longer see the mildew stains.
Let the art dry fully.
