Nearly everyone has encountered the unthinkable: Your smartphone landed in the toilet. Or you forgot to take off your smartwatch before jumping into the pool. Or maybe you meant to take those earbuds out of your pocket before running the laundry. What now?

Internet forums are chock-full of advice to dry out that drenched device, but problematic myths about liquid protection and repair make it hard for consumers to separate fact from fiction.

I’m a researcher who studies how technologies play a part in people’s everyday practices and experiences. My new book, “License to Spill: Where Dry Devices Meet Liquid Lives,” explores the wet-dry boundary in how people perceive and treat their electronic devices.

Here are five common myths about getting devices wet:

Myth 1: My device turned back on! It’s fine

While it’s a relief to see your technology rise from the dead, what you can’t see are subtle processes occurring inside, like corrosion. The breakdown of your device’s metal parts due to moisture often happens over time, in a period that can take place days, weeks or months after the offending incident.

That’s why even humidity from moist climates or your steamy shower can make a long-term impact, despite the fact that everything booted up right away after a splash or dunk.

Myth 2: My ‘waterproof’ device can tolerate any kind of wetness

The term “waterproof” is a controversial one – so controversial, in fact, that the Federal Trade Commission has strict rules about using the term in advertising, once even banning it from ad copy selling wristwatches.

Given the vagueness of the term, it’s better to examine different water resistance standards, such as ingress protection, or IP, ratings and MIL-SPEC, or ISO in the case of watches, and to read the fine print about what those standards actually cover.

Myth 3: My device has a great IP rating, so it’s been tested under real-world conditions

Companies often advertise IP ratings as a way to entice consumers to purchase their products, but it’s important to know that these ratings are based on contact with fresh water. If you’re worried about Jacuzzi suds or that tipped-over can of beer, there’s no guarantee that a manufacturer has tested your device in these – often sticky – situations, and an IP rating won’t account for them.

Myth 4: I’ve got some rice in the kitchen. I can fix this myself!

It’s natural to panic and seek out the quickest household solution when a spill or dunk happens, and a cup of rice is still a commonly sought-out option.

However, the rice hack doesn’t work very well, and rice particles can enter the device to cause even further damage. Aside from bringing your device to a professional repairer, you’re better off immediately powering down your product, removing its battery and plug if you can, and letting all the components dry over a day or two.

Myth 5: Well, this device is broken, but I’ve got a warranty to replace it

While you’re pulling your product from its watery grave, you might find relief in the fact that it came with a warranty. Not so fast.

Most traditional consumer technology limited warranties don’t cover liquid damage. These days, you usually need to purchase an add-on warranty, often called Accidental Damage from Handling. Beware, though: Even those policies may limit how many wetness “incidents” or “events” you’re allowed per year.

Keeping it realistic

Water resistance features on devices like laptops, tablets, smartphones and smartwatches have recently improved, but the deck is still often stacked against consumers who must wade through the hype of advertising claims, mystifying classification systems and penalizing policies.

That’s why it’s critical for manufacturers to think carefully and ethically about how their products are designed, marketed and serviced. In terms of design, water resistance is no longer a niche feature meant solely for industrial workers or outdoor adventurers. While it’s unrealistic to expect a device that’s designed to resist every hazard, it’s also unreasonable to ask consumers to tiptoe around the products that provide them with access to critical resources and social support.

It’s important for manufacturers to avoid promising consumers the Moon. Samsung Australia, for instance, paid AU$14 million in penalties for exaggerating its phones’ protection for swimming. It’s certainly fun to watch commercials with Lil Wayne spray a smartphone with champagne or see him dunk it in a fish tank, but if manufacturers are advising against these practices, then they shouldn’t be romanticizing them.

Sure, it’s probably common sense that your phone shouldn’t take a bath in champagne. Yet life is constantly happening around – and with – our devices, from the shower and the kitchen to the gym and the beach. This means that fairer policies around repair, like those promoted by the right-to-repair movement, and warranties should stop treating consumers like they’re “bad” users.

After all, we’re each just one splash away from crying over spilled milk.
