Problem #1: They Smell Musty
No one likes a stinky towel, especially after you've just taken a nice hot shower. If your clean towels have a lingering odor, try washing them using the hottest water the towels can tolerate along with 1 to 2 cups of vinegar. Then wash again with your regular laundry detergent. And always make sure you hang your towels so they can dry fully, post-use.
Problem #2: They Don't Dry Well
Believe it or not, this is a problem with newer towels. Washing and drying towels five times or more may help increase absorbency. Laundering will remove some of the coating manufacturers put on their towels to make them feel soft in the store and some of the dye, both of which interfere with a towel's absorption.
Problem #3: They're Shedding Lint
Again, the solution is to wash them. Laundering a few times should remove those loose fibers.
Problem #4: They're Fading
If you want to keep your towels bright and colorful, put vinegar in with your detergent the first time you wash them. Then dry them according to the manufacturer's instructions.
Problem #5: They Feel Like Sandpaper
No one wants their towel to feel super scratchy. Make sure you're not overdoing it with thde detergent; more doesn't mean "more clean." In fact, it can contribute to your towels feeling rough and excess detergent can breed bacteria over time. And skip the fabric softener every third of fourth load; otherwise it can inhibit absorption.
Problem #6: They're Just Not Fluffy Enough
Maintain your towel's fullness by fluffing, or shaking out, washed towels before placing them in the dryer and then fluffing again when you remove them.
