Introduction
Your CPU is the heart of your computer, processing everything from simple tasks to intensive operations. A dirty or improperly maintained CPU can lead to overheating, reduced efficiency, and potential hardware damage. But when it comes to cleaning, you might wonder, “Can I safely use 70% isopropyl alcohol for this task?” Let’s dive into the details.
Understanding Isopropyl Alcohol
What Is Isopropyl Alcohol?
Isopropyl alcohol (IPA) is a commonly used solvent with strong cleaning and disinfecting properties. It evaporates quickly, making it ideal for delicate tasks like cleaning electronics.
Differences Between 70% and 99% Isopropyl Alcohol
The percentage refers to the alcohol concentration.
