Yes you can but before cleaning, make sure the motherboard is unplugged from the power source. Make certain that it has also cooled. After cleaning, wait a while for any lingering alcohol traces to disappear before plugging anything back in. Naturally, you should also be gentle febore doing this.We give you clear understading of usage of 91 isopropyl alcohol to clean your CPU after reading this article you gather more knowledge about it.

What Is 91 Isopropyl Alcohol? How Is It Made?

91 Isopropyl alcohol is a clear chemical element which is flammable. It smells a bit like vodka or other spirits, just without any kind of scent other than alcohol. Many manufacturers make it by adding water to propene. I know that your curious mind want to know what is propene ? It’s like self steamed and heated out of some chemical elements and mixture of other hydrocarbons, then distilling the mixture to a desired strength, similar to how liquor is made.
It is frequently sold in a few predetermined alcohol-to-water ratios: 70% and 90–91% are the most prevalent, but you may also see 60% or 95–99% at hardware and specialty supply stores.

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

On circuit boards and other electrical components, it is preferable to stay away from isopropyl mixtures that are less than 90%. 70% might work in a pinch to remove glue from metal or plastic, but you’ll want to be careful not to get any on wiring or circuitry. That inferior material has enough water to take longer to evaporate and, when you’re done, may still contain traces of water’s contaminants.
90% is adequate for the majority of uses. Although 99% might seem ideal in theory, it can be difficult to locate in some locations. When you see a bottle, grab it, but don’t stress too much about the remaining 10%.

What About Other Compounds that Have High Alcohol Percentages?

We advise sticking with isopropyl alcohol and water, which are both well-known substances. The high-alcohol solutions like surgical spirits, rubbing alcohol, denatured alcohol, and others frequently have additional compounds, fragrances, or other ingredients that have different qualities than IPA or should not be used around wires and boards. It might be advisable to wait if the label doesn’t list water as the only inactive ingredient and isopropyl alcohol as the only active ingredient.

This is especially true with acetone, which is used to remove nail polish. At least for the kind of adhesives frequently used in electronics, acetone is a more potent adhesive remover than isopropyl alcohol. However, acetone also harms ABS polymers, which are widely used in electronics. Because of this, we add a small amount of acetone to our adhesive remover to increase its effectiveness but not to the point where it can melt plastics, assuming you wipe it up reasonably quickly.

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

You should disconnect the battery before doing any work that could put you in touch with electrical circuits, as almost every iFixit guide emphasizes. Once the battery is removed it’s much less likely that you’ll accidentally make a spark or expose isopropyl to heat. It’s not likely that electrostatic discharge from your clothes or rugs will start a fire, but it’s still best to stay away from it. So, the main thing you should look for are bigger capacitors in bigger devices, which can keep a charge even when they are not plugged in. This won’t be a problem for most fixes.

It doesn’t matter what you use isopropyl alcohol for. You should handle it in your home like any other flammable material with strong vapors. Keep it away from flames, high heat, and sparks. Keep it closed tightly when not in use to stop water from evaporating and going to waste. And don’t use it in small rooms that don’t have enough air flow.

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

  • It’s relatively inexpensive, and it does a few important jobs at once. Let’s have a look at a glance what are those thing?
  • Gets rid of fingerprints, oils, adhesives, soldering flux, residues, and other pollutants
  • Like many ethanol compounds, it doesn’t leave behind any oils or residue.
  • Quickly evaporates (at least in places warmer than 60 degrees Fahrenheit)
  • Not too dangerous as long as you work in a well-ventilated place.
  • At amounts of 60 to 70 percent, it kills viruses and bacteria.

Fully mixes with water and then dissolves with it. This makes it the best way to clean up liquid spills on electronics and keep them from rusting.

No matter what you use it for, you should handle isopropyl alcohol in your home like any other flammable material with strong vapors. Do not put it near a light, very hot metal, or sparks. When not in use, keep it closed tight.
