This isn’t a stain. It’s buildup. PitRx is a deodorant buildup remover for shirts that helps treat yellow armpit stains, white marks, and dark wet-look patches caused by stubborn deodorant and antiperspirant residue. Each bottle treats ~20 shirts — making it a simple, cost-effective way to restore your wardrobe. PitRx removes the stubborn waxy buildup caused by antiperspirant — the deodorant stains, pit stains, and underarm stains that won’t come out in the wash. These stains aren't just sweat. They're a combination of aluminum, body oils, and deodorant residue that bond to fabric over time. PitRx breaks down that buildup so it can be fully washed away. ✔ Fast spray-on application Why it works Deodorant stains aren't just surface-level. Over time, antiperspirant forms a layered buildup inside the fabric — trapping oils, residue, and discoloration. Regular detergent can't break this down. PitRx is specifically formulated to dissolve that buildup so it releases during washing. How to use 3 simple steps. No complicated routine. Spray directly onto the stained area Let sit for 10–20 minutes Wash as normal For best results, treat stains before washing. Agitation may be required for stubborn stains.Ready to finally fix your shirts for good?
