Is Isopropyl Alcohol Used To Clean Electronics

We've talked earlier near how the pandemic has shown some serious strain on our global supply chains. In one case upon a time information technology came for isopropyl alcohol. While IPA may not exist hard to find, or triple the usual toll, nosotros've still got the details, and alternatives, right here for yous.

We know, rely on, and recommend isopropyl booze (a.chiliad.a. isopropanol, or IPA) for many of our techniques and guides. It's pretty simple stuff, merely it is sold in different ways, and recommended for a myriad of uses.

Understandably, people have questions. Is "rubbing alcohol" or "surgical spirit" the same matter? What percentage of isopropyl do I need for electronics work or disinfecting? Can I apply annihilation else on my electronics? And, hey, is this stuff going to catch on fire if I cause a spark?

Let's clean upwards these questions.

What Is Isopropyl Booze? How Is It Made?

Isopropyl booze is a articulate chemical that is flammable. It smells a bit like vodka or other spirits, but without any kind of scent other than alcohol. Manufacturers make it by adding h2o to propene (itself steamed and heated out of propane and other hydrocarbons), and so distilling the mixture to a desired strength, similar to how liquor is made.

Information technology's ordinarily sold in a few set percentages of alcohol-to-water: 70% and 90/91% are most common, just you'll sometimes come across threescore% or, at hardware and specialty supply stores, 95-99%.

Why Do You Recommend Isopropyl Booze for Cleaning Electronics and Removing Adhesive?

It'due south widely available (at least in non-crisis times), it's relatively inexpensive, and it does a few important jobs at once. Isopropyl:

• Dissolves oils, adhesives, soldering flux, residues, fingerprints, and other contaminants
• Leaves no oils or traces, dissimilar many ethanol compounds
• Evaporates apace (at least in spaces above threescore degrees Fahrenheit)
• Is relatively non-toxic, bold you're working in a decently ventilated area
• Disinfects viruses and bacteria (at concentrations of 60/70 percent)
• Mixes with water fully and and then evaporates with it, making it the best way to remove and preclude corrosion damage from liquid spills on electronics.

I Can Only Discover 70% Isopropyl Booze. Can I Utilise It to Make clean My Devices?

Information technology'due south best to avert using whatsoever isopropyl mixture below 90% on circuit boards and other electrical bits. If you're simply cleaning the agglutinative off something metal or plastic, lxx% might practice in a pinch, simply you'll want to exist sure not to spill it onto circuits or wires. There'southward plenty water in that lower-grade stuff that it will take longer to evaporate, and may leave behind trace impurities from the water when you lot're finished.

ninety% works fine for near purposes. 99% might be technically optimal, just information technology's trickier to notice in some places. Grab a bottle when you can find it, but don't worry besides much virtually the last 10%.

What Near Other Compounds that Accept Loftier Alcohol Percentages? Nail Smoothen Remover?

We suggest you lot stick to something y'all know and has known ingredients: isopropyl booze and water. Rubbing alcohol, denatured booze, surgical spirits, and other loftier-alcohol solutions oftentimes comprise other chemicals, scents, or other substances that have different backdrop than IPA, or are a bad idea effectually boards and wires. If the package doesn't have isopropyl alcohol as the only active ingredient, and water as the only inactive, it might be best to hold out.

This is particularly true for nail polish remover, or acetone. Acetone is a stronger adhesive remover than isopropyl alcohol, at least for the kinds of adhesives often used in electronics. But acetone too amercement ABS plastics, the virtually common in electronics. That'south why we include but a little acetone in our adhesive remover, to make it fifty-fifty more effective, but not and so much that it volition cook plastics, presuming yous wipe it up fairly quickly.

What About Vodka?

Most vodka, and nearly liquor generally, is around 40% alcohol by volume, so no, it's a bad idea for electronics repairs.

But I've Got This Booze That's Really Loftier-Proof.

You're better off saving that for large batches of party punch, given the toll. Ethanol/ethyl booze is not the same affair equally isopropyl booze, either.

Volition Isopropyl Damage My Screen? My Laptop Keys? Other Things Within My Device?

We'll simply tell you to use isopropyl alcohol on surfaces where information technology's safe to do and so in our guides. And we try to warn you when spills or an abundance of liquid tin crusade damage. In our guide to replacing the battery in a 2013 fifteen-inch MacBook Pro, we note that our own adhesive remover (the majority of which is isopropanol, but also a small amount of acetone) can impairment the anti-glare blanket on your brandish, and the plastic on the embedded speakers.

Generally, metal and excursion boards don't take a problem with adhesive remover, merely you should be cautious effectually brandish components (especially the LCD or OLED bankroll behind a screen), plastics, and, obviously, anything that is glued together that yous desire to stay glued together. Generally, a cautious approach is best; even better is a little pre-fix research. Electronics cleaning vendor Techspray has a material-by-cloth list of what reacts to isopropyl alcohol. If you're non sure, don't put a bunch of booze on it (a good general rule for life, you might find).

Nosotros recommend isopropyl alcohol as one of the steps to cleaning out your keyboard. Only annotation that we recommend a damp towel, not pouring the stuff straight on.

Many device makers are clarifying what is condom to wipe with sanitizing solutions. Microsoft says yous can clean the felt-like Alcantara cloth on its Surface products with a lxx% alcohol solution. Apple tree used to suggest that you had to be really careful effectually its screens to avert removing the oleophobic coating, merely now using a 70% solution is at the top of the official "Cleaning your iPhone" folio. Searching for cleaning or maintenance instructions for your device is a good identify to commencement.

Information technology'southward Flammable Stuff, with a Poison Alarm Label On It. How Concerned Should I Be?

Nearly every iFixit guide is congenital around getting to the battery and disconnecting it before you lot do whatever work that would put you in contact with electrical circuits. One time the battery is disconnected (or you've unplugged the device, if it lacks a battery), your take a chance of accidentally creating a spark, or exposing isopropyl to oestrus, is much reduced. Electrostatic discharge from your clothing or rugs is quite unlikely to cause a fire, just information technology's ever a good thought to avoid it. The main thing you want to look for, then, is larger capacitors in bigger devices, which can store a accuse fifty-fifty afterwards disconnection from power. For most repairs, this isn't an issue.

Regardless of the use, you lot should treat isopropyl alcohol like any other flammable substance with strong vapors in your house. Don't expose it to flame or high heat or sparks. Keep it tightly airtight when non in use (this besides prevents wasteful evaporation). And don't utilize it in enclosed spaces with poor ventilation.
