This is weird. On Sunday Steve replaced the cleaning cartridge on his new Braun shaver. It fits into a stand and self cleans using a cartridge full of some sort of cleaning solution. About an hour later our carbon monoxide detector went off. I quickly moved it downstairs closer to the furnace and water heater. Nothing happened. Steve got a new carbon monoxide detector and plugged it in the old location which happens to be the outlet where his shaver is plugged in.
Monday he didn't put the shaver through the cleaning cycle. Tuesday he did and about an hour later the new alarm is going off. The digital display read "HI". I opened the window and turned on the fan and waited for the unbelievably piercing alarm to stop. After it stopped I moved it across the hall to another room and took the kids and left for an hour. When we got home the alarm was going off and the digital display now read "96". I called the gas company and they sent someone out within an hour to check it out. He thoroughly checked my home, ran the furnace and water heater and checked to see what their output was. He said they were both burning clean and was at a total loss as to the high level of carbon monoxide.
After a rather sleepless night (wondering if at any moment that infernal shrieking alarm was going to go off) we decided it was just a fluke. Couldn't figure it out and the day went by as usual. No alarm, but then again, he hadn't cleaned his shaver that day. This morning when the alarm started to shriek, I called Steve and he had used the cleaning cycle. Mystery solved. The shaver puts high levels of carbon monoxide into my home every time he cleans it. This time it read 149. REALLY high. I aired out the house and chucked the cleaning contraption in the garage.
I sent an email to Braun (they were closed for training) and to the Consumer Product Safety Commission. I'll let you know what they say.
