Do I treat them like I do other water-adverse electronics?
What do the manuals for them say? I regularly get my electric toothbrush wet while using and cleaning it (and can’t imagine how it couldn’t get wet, either from the sink or saliva). But I don’t think my electric razor is meant to get wet, although I think I’ve seen models that can be used in the shower.
“Electronic”? Aren’t they just tiny motors on a switch? That’s electric.
There definitely are electronics in these devices. For example, my Braun Oral-B electric toothbrush has an LCD display that indicates the brushing mode and the amount of time that I’ve been brushing.
BTW, I’ve been looking at the Amazon.com listings for electric razors. Generally the ones designed to get wet are called wet/dry razors.
My Sonicare says I can use it in the shower.
I don’t think it would be wise to immerse my beard trimmer, but the attachments are meant to be rinsed in water.
How does one brush one’s teeth and then clean off the brush without the aid of water? 
Any device that plugs to the wall when in use could be dangerous in use if the water gets inside. Battery operated devises have voltage so low that they are not dangerous. Also, they are insulated pretty well to protect their electronic parts so go ahead, use them freely, but follow directions too.
yes electric, sorry, the distinction escaped me.
neither manual comments on whether the product is water-adverse.
the razor is AAA battery powered.
the toothbrush is rechargeable via a proprietary charger.
I guess the toothbrush’s coming into contact with water is unavoidable, but can an electric razor be used in the shower if its instructions do not specifically mention it?
What are the model numbers of the devices?
I would call mine both. It has an electric/battery motor, but also an LCD display on-board plus an external one that communicates with the brush via Bluetooth, and sits on a shelf. So it’s also definitely electronic.
You have blue teeth? I suspect dog germs are involved.
Uh, Oh! Should I soak them in cleanser and bleach for a few days? I might not survive!
As I mentioned in your other thread, your toothbrush may not even have any direct electrical connection with the charger; the two may be acting as two halves of a transformer.
I have a cheapo Phillips electric brusher, which is basically a molded plastic casing with a button on it, and a attachment for the brush itself on top. Altough the booklet in the box said do not submerge I’ve done so on many occasions, and no harm has come to it.
I’m guessing most electric toothbrushes are like this now - more or less completely shielded from water. And, as noted above, must likely all by now use inductive charging, so there is nothing that can short out if the brush is submerged.
Gee, I dunno. My Oral-B rechargeable toothbrush’s instructions say I should rinse both the detachable brush and the handle, where the motor is. I have used my AAA battery powered Gillette razor in the shower without any problem. How can you use a razor without getting it wet?
:eek: WHY???
I would not do it unless the razor is explicitly designed to be used this way. I will not have enough voltage to be dangerous to you, but if water should get into the electrics it might short itself out and cease to work. Unlike a toothbrush, electric razors do not need to be got wet to be used, so I doubt whether most of them are designed to be very waterproof.
Don’t know about razors (haven’t used one in 46 years), but my toothbrush has no contacts and obviously charges inductively. The charger, on the other hand, has a cord that plugs in and I would keep that dry.
I use my Gillette Fusion Power in the shower all the time with no problems to date. No idea if the manual says don’t.
