Friendly warning: this before and after might make you question every pair of running trainers you own. 😳
We genuinely didn’t think these looked THAT dirty… until we cleaned one.
Trail dust, mud and miles build up gradually—but that side-by-side doesn’t lie. A little Trainer Trash Cleaner and our trusty brush were all it took to bring them back to life.
Don’t trash them. Wash them. 🧼👟
