Piles of silica gel packets

They let you know to throw them away.

They let you know to not eat them.

Some would possibly let you know that they’re harmful.

However these little packets of silica gel, often known as desiccants, might save the lifetime of your know-how.

This jogged my memory of a publish by my ZDNet tech colleague David Gewirtz who not too long ago had the misfortune of dunking your AirPods Professional in your morning drink.

He took some silica gel packets, threw them in an hermetic field together with his AirPods submerged, and left them there for a day.

And your costly headphones lived to struggle one other day.

As somebody who cleaned, dried, repaired, and likewise pitied owners for lifeless tech, I believed I might chime in right here with a few of my ideas on drying soggy tech.

Silica gel is a desiccant, which is a elaborate manner of claiming that it absorbs moisture (it really technically adsorbs moisture, however the distinction is not essential right here) from the environment. It might take in about 40% of its weight in water, and might cut back the humidity of the air round it to about 40% (assuming there may be sufficient silica gel and the container is sealed).

And no, you possibly can’t use rice to dry issues. Not solely does this not work, but it surely additionally fills your gadget with disgusting rice particles.

The aim of these little packets of silica gel that you simply discover together with the gadgets you purchase is that they’re used to maintain the encompassing air drier than the ambient air, cut back corrosion, and inhibit mould progress.

This brings us to the primary drawback with silica gel packets: they’ve been within the air absorbing moisture for weeks, months, and even years, and the quantity of moisture they will entice and maintain may be restricted.

You could recharge silica gel by heating itor you should buy new issues, both in a bag or in small packages. You can even use a product like DampRid.

When you wish to be ready for any water mishap, it’s possible you’ll wish to contemplate buying a some pre-made moisture absorbing luggage specifically designed for digital merchandise. They’re just a few {dollars} and have a protracted shelf life.

One other factor to notice about silica gel is that it doesn’t “dry out digital elements”.

As a substitute, what it does is it dries out the air, which suggests it’s essential evaporate that moisture within the air for the silica gel to entice it. That is why it is a good suggestion to place the merchandise that should dry in a field with the gel packs and retailer the field in a heat room. That mentioned, don’t place it in a scorching location reminiscent of on prime of a radiator or in direct daylight, as the warmth might injury the gadget you are attempting to dry.

You also needs to take away any seen liquid earlier than putting it within the field to cut back the quantity of labor the silica gel has to do.

And then you definitely wait. In the future. A few days. One week.

Okay, however does it work?

To reply this query, we have to know the way water damages your gadgets.

quick circuit

A brief circuit is when the electrical energy inside a tool takes a path it should not, which in flip causes injury.

Pure distilled water is just not conductive, however the extra “contaminants” added to the water (faucet water, sea water, cola, espresso, mud), the extra conductive the water is and the extra possible it’s to wreck a product. powered gadget. .

If a tool falls right into a liquid and instantly stops working, this injury was probably brought on by a brief circuit.

That is why it is a good suggestion to take away the battery from a moist gadget every time attainable and never flip it on till it is dry.


In case your gadget did not die instantly when uncovered to liquids, then the subsequent factor to fret about is corrosion.

Corrosion is a long-term factor and it builds up over time. It might trigger quite a lot of injury, consuming away at circuit boards and elements.

The corrosion may be cleaned with one thing like contact cleaner or isopropyl alcohol, however that will not repair the injury, and I feel as soon as the corrosion has began all you are able to do is sluggish it down.

I’ve misplaced rely of the variety of gadgets I’ve come throughout that “simply die” for no obvious cause, however once you open them you see that the rationale was that sooner or later a liquid was spilled on it and that in flip induced the formation of corrosion (this is quite common with sport consoles and handheld gadgets). This corrosion seems to be like a advantageous gray-green powder that we name “inexperienced crusts” within the enterprise.

Bodily injury

Water can get on screens and audio system, or on buttons and switches, rendering them inoperable. Typically drying out a tool fixes this (as with switches), however it could actually trigger everlasting injury to elements like shows.

A water broken circuit board displaying a extreme case of “the inexperienced scabs”.

The very fact is {that a} quick circuit can kill your gadget earlier than it even will get near a silica gel packet. Additionally, you’ll have been fortunate and prevented a brief circuit, however nonetheless have corrosion issues sooner or later.

I have a tendency to think about actions taken after a tool sustains water injury as little greater than shopping for time. Now, it might purchase months or years, and it might purchase sufficient time for the gadget to die from another trigger, however even in conditions the place a tool may be utterly disarmed, I can totally clear all the pieces with isopropyl alcohol both contact cleaner sprayit’s virtually not possible to take away all traces of the liquid, particularly whether it is one thing sticky like glue or juice.

And relating to acidic or harsh liquids like salt water, corrosion can begin nearly instantly.

In actual fact, salt water, carefully adopted by glue, is a loss of life sentence for electronics. Salt water is just not solely extremely conductive, dramatically growing the prospect of a dangerous quick circuit, but it surely’s additionally extremely corrosive, so even when your gadget survives submersion, corrosion injury might kill it a number of weeks or months later. .

Once I cannot open a tool to scrub it, I will focus my efforts on drying anyplace liquids can get into the gadget, locations like charging ports. You might fastidiously use isopropyl alcohol or spray contact cleaner at these entry factors to attempt to dislodge the fluid, however you have to be cautious to not trigger additional injury when doing so.

One other manner you should utilize silica gel packets (or free silica gel beads) is to position a soaked gadget in a field with them when you put together to do additional drying, both your self or by utilizing a service. skilled like like redux.

At the least placing the gadget in an hermetic field, which might be additionally hermetic, prevents you from spraying it a second time!

So the underside line is that these silica gel packets can come in useful relating to drying out a soggy digital gadget. It is a fast and easy factor you are able to do, and it would not contain opening a tool or doing any guide cleansing.

However there are not any ensures.
