What Cleans Fingerprints?

A 1:1 solution of water and rubbing alcohol effectively cleans fingerprints.

Here's a more detailed breakdown of methods and considerations for cleaning fingerprints:

Effective Cleaning Solutions

Isopropyl Alcohol (Rubbing Alcohol) and Water Mixture: A diluted solution of isopropyl alcohol is a common and effective fingerprint cleaner.
- Ratio: Mix equal parts of isopropyl alcohol (70% or higher concentration is recommended) and distilled water.
- Application: Dampen a clean, lint-free microfiber cloth with the solution. Avoid oversaturating the cloth.
- Technique: Gently wipe the affected surface in a circular motion. Follow up with a dry microfiber cloth to remove any residue.
Commercial Fingerprint Cleaners: Several commercial products are specifically formulated to remove fingerprints from various surfaces. These often contain a blend of solvents and surfactants.
- Advantages: Convenient and often formulated for specific surfaces (e.g., stainless steel, glass).
- Disadvantages: Can be more expensive than DIY solutions and may contain harsh chemicals. Always read and follow the manufacturer's instructions.
Distilled Water: For light smudges and on certain surfaces, distilled water alone can be surprisingly effective.
- Application: Use a slightly damp microfiber cloth.
- Best For: Smooth, non-porous surfaces like glass and some metals.

Surface Material: The best cleaning method depends heavily on the surface you're cleaning. What works on glass might damage wood or stainless steel.
Microfiber Cloths: Always use clean, lint-free microfiber cloths to prevent scratching and smearing.
Gentle Pressure: Avoid applying excessive pressure, which could damage delicate surfaces.
Test in an Inconspicuous Area: Before cleaning an entire surface, test the chosen cleaning solution in a small, hidden area to ensure it doesn't cause discoloration or damage.
Safety: When using rubbing alcohol or commercial cleaners, ensure proper ventilation and avoid contact with skin and eyes.

Surface	Recommended Cleaner	Additional Notes
Glass	Isopropyl alcohol and water mixture, distilled water	Use a squeegee for streak-free results.
Stainless Steel	Commercial stainless steel cleaner, mild soap & water	Wipe in the direction of the grain to avoid streaks.
Wood	Wood-specific cleaner, very diluted mild soap & water	Avoid excessive moisture. Dry immediately after cleaning. Test in an inconspicuous area first.
Electronics	Microfiber cloth (dry or slightly damp with water)	Power off and unplug the device before cleaning. Avoid getting moisture into openings.
