I know, I know—vinegar smells like pickles. But trust me, it works wonders. Add half a cup of white vinegar to your washing machine’s rinse cycle. The vinegar breaks down leftover detergent and naturally relaxes the cotton fibers.
Don’t worry about the smell—it completely disappears once the clothes are dry. You’ll just be left with fabric that feels like you’ve been petting a soft, sleepy cat.
You can also toss in half a cup of baking soda during the wash cycle itself. It boosts your detergent’s power and softens water, which helps your clothes feel less like sandpaper. It’s like giving your laundry a gentle spa treatment.

This helps lock in the dye and relaxes the fibers, so your first wear isn’t a battle. I did this with a pair of stiff denim shorts, and they went from “board game tablecloth” to “comfy Saturday afternoon” in one soak.
Just rinse them with cold water after the soak, then toss them in the wash as usual. Your clothes will thank you with a softer feel that lasts.
