Can drain openers cause damage to faucet finishes?
Yes. Oh, most definitely, yes. If you’re pouring drain opener down your drain, and some of that drain opener gets on the drain flange or faucet, rinse the drain opener off as soon as possible. Usually, your finish won’t be harmed if you follow the manufacturer’s instructions for use, and make sure the drain cleaner isn’t left on the finish for longer than 30 minutes.
