Spots and stains allowed to remain without treatment will gradually oxidize, set, and become permanent. We are trained and equipped to deal with stains, and if anyone can safely remove them, we can.
Don’t iron stained or soiled clothes trying to get just one more wearing out of them. Ironing dirty clothes will set stains and drive soil deeper into the fabric. Not good.
Never put a garment away with a stain on it. Stains containing sugar and even small amounts of any food are a tasty treat for insects, leading to holes from eaten fibers. Also, putting clothes away without cleaning them almost guarantees some discoloration or oxidation of stains.
Dry cleaning will remove perspiration and body oil. That’s a good thing because these two elements contribute to stains and fabric degradation – and will eventually produce a lingering odor if left untreated.
