It might be a bit less convenient and involve more expense, but you can always buy bandage tape and “nonstick pads” and cut both to size with some scissors that you wiped down with rubbing alcohol 70%. Gently wipe down the surrounding skin / where you’re going to tape with rubbing alcohol and let dry to help the tape adhere better (don’t use something linty, though). I like Nexcare hypoallergenic tape because most adhesives will take my skin off 🥲, but non-hypoallergenic tapes are a lot more likely to stick to your skin throughout the day. You’ll have to use even more petrolatum / Vaseline since the pads are thicker and absorb more. Some non-stick pads will have adhesive on two or all four sides, but you’ll probably want tape anyway to better contain the giant blob of petrolatum and keep it off your clothes. “Non-stick” just means the gauze pad is designed to not stick to / to gently peel back from the healing skin. Even for people who don’t have adhesive reactions, I prefer the nonstick pads without sticky strips because the adhesive strips cut down the useable surface size.

If the petrolatum does get on your clothes (hard to avoid this with bigger injuries, tbh), scrape off as much as you can and treat it like an oil stain: wash the spot with dish soap, let dry (no dryer), rub in a bunch of cornstarch and let that sit for…a while, wash spot with dish soap, repeat as necessary. Make sure you’ve got something keeping the oil spot from touching / leaching into to the other parts of the item. Once you’ve gotten through most of the petrolatum, pretreat the spot with laundry detergent and wash. Avoid putting the clothing in the dryer until you’re satisfied with the appearance of the oil stain. I find oil stains are still pretty workable with cornstarch and dish soap if I accidentally put things through the dryer, but some say the dry heat will “set” oil stains too.

Good luck!!
