To share with collectors who own Delrin (a Dupont tradename) IWC Porsche Design watches (mine is a IW3701)
Thanks to a tip on an old Reddit thread on how to clean a Delrin knife handle, I was able to revive my IW3701 bracelet with a good bath of business-class supplied bottles of perfume. 90% Ethanol could work even better, I read. But the perfume bath worked well enough, plus it smelt nice 😇
