Just like Apple’s HomePod, the similar silicone base on the Sonos One smart speaker can also leave white marks on some types of wood furniture.
Mike Prospero from Tom’s Guide had been testing both the Apple HomePod and Sonos One on a wood table at his home:
When I learned yesterday that Apple’s HomePod speaker—which I had been testing—can damage oil-stained wood, I was more than a little concerned, as it had been sitting on my cabinet for quite some time.
When I got home, I saw a large white ring, a telltale indication that the HomePod’s silicone base had messed up the finish. But, as I was inspecting the damage, I noticed a series of smaller white marks near where the HomePod was sitting.
A closer inspection revealed that the Sonos One speaker, which also has small silicone feet, had made these marks on my cabinet. Looking around the top of the cabinet, I noticed a bunch of little white marks, all left from the Sonos Ones as I moved them around. So, they will damage your wood furniture, too. We’re awaiting comment from Sonos.
After two different sites noted that the HomePod made the marks on some oil-finished furniture, Apple published a new support document – Cleaning and taking care of HomePod. Apple notes that the silicone on the base of the speaker can “leave mild marks when placed on some wooden surfaces.”
