Cleaning each petal of your faux silk flowers can be tedious, and specialty cleaning sprays can be expensive, but there is an easy and affordable solution to rejuvenate them: salt.
To use this hack, put a fake silk flower in a paper or plastic bag, or a resealable container, and add 2 tablespoons of salt, preferably a coarser variety like kosher or rock salt.
Seal the bag or container and gently shake it for a minute, allowing the salt to loosen dirt and dust from the flowers. Then, take out the flower and shake off any residual salt.
If any salt remains, use a feather duster or a hair dryer on a cool setting to remove the lingering grains. If you’re out of salt, the same technique can be applied with cornmeal.
