Compared to higher-concentration alcohol, 70% isopropyl alcohol is often cheaper and easier to find, making it a practical choice for most users.

Potential Risks

1. Water Residue

70% alcohol contains 30% water, which can leave moisture behind if not allowed to dry completely. This moisture might harm sensitive electronic parts like your CPU.

2. Slower Drying

Compared to 90%-99% alcohol, 70% takes longer to evaporate. This means you need to wait longer before reassembling your computer.

3. Risk of Static Damage

Improper handling can cause static electricity, potentially damaging your CPU. Always use anti-static precautions like a grounding strap while cleaning.

4. Limited Strength for Tough Residue

It may struggle to clean stubborn thermal paste or grease compared to higher alcohol concentrations, requiring extra effort or multiple applications.

Comparison: 70% vs. 90%-99% Alcohol

Drying Speed: 90%-99% alcohol dries faster because it has less water. This is helpful when cleaning CPUs as it reduces the chance of moisture lingering.
Residue: 70% alcohol may leave small water spots due to its higher water content. 90%-99% alcohol leaves almost no residue, making it better for sensitive components.
Cleaning Strength: Higher concentrations (90%-99%) work faster and are more effective on tough residues like dried thermal paste. 70% alcohol may need repeated applications for similar results.
Availability: 70% alcohol is easier to find and cheaper, while 90%-99% alcohol might not be readily available in all stores.
Safety for Electronics: Both concentrations are safe when used properly, but 70% alcohol requires extra care to avoid water-related risks.

When to Avoid 70% Alcohol

Avoid using 70% alcohol if moisture is a concern, like with sensitive electronic circuits. It’s also less effective on stubborn thermal paste or grease. For better results, use 90%-99% alcohol, which evaporates faster and leaves no residue.

Alternatives to Alcohol

1. Thermal Paste Cleaners

Specially designed cleaners remove thermal paste effectively without leaving residue. They’re safe for electronics and often work better than alcohol for stubborn residue.

2. Distilled Water
