What Type Of Isopropyl Alcohol Is Good For Cleaning Computers

We've talked before about how the pandemic has shown some serious strain on our global supply chains. One time upon a time it came for isopropyl booze. While IPA may not exist hard to observe, or triple the usual cost, we've notwithstanding got the details, and alternatives, right here for y'all.

We know, rely on, and recommend isopropyl alcohol (a.chiliad.a. isopropanol, or IPA) for many of our techniques and guides. It'southward pretty simple stuff, but 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 thing? What percentage of isopropyl do I need for electronics work or disinfecting? Can I utilise anything else on my electronics? And, hey, is this stuff going to take hold of on fire if I cause a spark?

Permit'southward clean up these questions.

What Is Isopropyl Alcohol? How Is It Made?

Isopropyl alcohol is a clear chemical that is flammable. Information technology smells a flake like vodka or other spirits, just without any kind of scent other than alcohol. Manufacturers arrive by adding water to propene (itself steamed and heated out of propane and other hydrocarbons), and then distilling the mixture to a desired strength, similar to how liquor is made.

It'southward usually sold in a few set percentages of booze-to-h2o: 70% and 90/91% are most common, simply you'll sometimes see sixty% or, at hardware and specialty supply stores, 95-99%.

Why Practise Y'all Recommend Isopropyl Alcohol for Cleaning Electronics and Removing Adhesive?

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

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

I Tin can Only Find 70% Isopropyl Alcohol. Can I Use It to Clean My Devices?

It's best to avert using any isopropyl mixture beneath 90% on circuit boards and other electric bits. If you're simply cleaning the adhesive off something metal or plastic, 70% might do in a pinch, only you'll want to be certain non to spill it onto circuits or wires. There'south enough h2o in that lower-grade stuff that it volition take longer to evaporate, and may leave backside trace impurities from the h2o when you lot're finished.

ninety% works fine for almost purposes. 99% might be technically optimal, but it'south trickier to find in some places. Grab a canteen when y'all tin can find information technology, merely don't worry too much about the final 10%.

What About Other Compounds that Have Loftier Booze Percentages? Nail Polish Remover?

We suggest you stick to something yous know and has known ingredients: isopropyl alcohol and water. Rubbing alcohol, denatured alcohol, surgical spirits, and other loftier-booze solutions oftentimes comprise other chemicals, scents, or other substances that take different backdrop than IPA, or are a bad idea around boards and wires. If the packet doesn't have isopropyl alcohol as the merely active ingredient, and water as the but inactive, it might exist best to agree out.

This is particularly true for smash smooth remover, or acetone. Acetone is a stronger adhesive remover than isopropyl alcohol, at least for the kinds of adhesives ofttimes used in electronics. But acetone as well damages ABS plastics, the nigh common in electronics. That's why we include just a picayune acetone in our adhesive remover, to arrive even more effective, only non so much that it will melt plastics, presuming you wipe it up fairly speedily.

What About Vodka?

Well-nigh vodka, and most liquor mostly, is effectually 40% booze past volume, and then no, information technology's a bad idea for electronics repairs.

Simply I've Got This Booze That'southward Really High-Proof.

Yous're better off saving that for big batches of party punch, given the price. Ethanol/ethyl alcohol is not the aforementioned affair equally isopropyl alcohol, either.

Will Isopropyl Impairment My Screen? My Laptop Keys? Other Things Inside My Device?

We'll but tell you to employ isopropyl booze on surfaces where it'south safe to exercise so in our guides. And we try to warn you when spills or an affluence of liquid can cause damage. In our guide to replacing the battery in a 2013 15-inch MacBook Pro, we notation that our own agglutinative remover (the majority of which is isopropanol, but also a small amount of acetone) can damage the anti-glare coating on your display, and the plastic on the embedded speakers.

Generally, metal and circuit boards don't have a problem with adhesive remover, but y'all should be cautious around display components (specially the LCD or OLED backing behind a screen), plastics, and, plain, anything that is glued together that you want to stay glued together. Generally, a cautious approach is best; even meliorate is a little pre-ready research. Electronics cleaning vendor Techspray has a material-by-material list of what reacts to isopropyl alcohol. If you're non certain, don't put a agglomeration of alcohol on information technology (a good general rule for life, yous might find).

We recommend isopropyl alcohol every bit one of the steps to cleaning out your keyboard. Simply 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 you tin clean the felt-similar Alcantara textile on its Surface products with a 70% alcohol solution. Apple used to suggest that y'all had to be really careful effectually its screens to avoid removing the oleophobic coating, simply at present using a 70% solution is at the elevation of the official "Cleaning your iPhone" page. Searching for cleaning or maintenance instructions for your device is a practiced place to first.

It's Flammable Stuff, with a Poison Warning Characterization On It. How Concerned Should I Be?

Nearly every iFixit guide is built around getting to the battery and disconnecting it before you exercise any work that would put yous in contact with electric circuits. Once the battery is disconnected (or you've unplugged the device, if it lacks a battery), your chance of accidentally creating a spark, or exposing isopropyl to heat, is much reduced. Electrostatic discharge from your clothing or rugs is quite unlikely to cause a fire, but information technology's e'er a practiced idea to avert it. The main affair yous want to look for, and then, is larger capacitors in bigger devices, which can shop a accuse even subsequently disconnection from power. For most repairs, this isn't an issue.

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