Cleaning eyewear with 70% isopropyl alcohol is generally safe and effective, but it's essential to exercise some caution to avoid any potential damage. Isopropyl alcohol is a common and widely used cleaning agent for eyeglasses because it evaporates quickly and leaves behind minimal residue. It is effective in removing oils, fingerprints, and other debris from lenses.
Here are some tips for safely cleaning your glasses with 70% isopropyl alcohol:
Dilution: 70% isopropyl alcohol is generally considered safe for cleaning eyeglasses. Higher concentrations (e.g., 90% or higher) might be too strong and could potentially damage coatings on the lenses. The 70% concentration is a good balance of cleaning power and safety.
Avoid prolonged exposure: While 70% isopropyl alcohol is safe for occasional use, it's essential not to use it excessively or regularly. Prolonged exposure to alcohol may eventually affect certain lens coatings or materials.
Apply gently: When cleaning your glasses with isopropyl alcohol, be gentle with the lenses. Avoid using excessive force, as rubbing too hard can scratch or damage the lens surface.
Check for coatings: Many modern eyeglasses come with anti-reflective, anti-scratch, or other specialized coatings. While isopropyl alcohol is generally safe for these coatings, it's essential to check with your optician or the manufacturer to ensure it won't harm your specific lenses.
Use a soft cloth: To avoid potential scratches, use a soft microfiber cloth or a lens cleaning cloth specifically designed for eyeglasses. Avoid using paper towels, tissues, or other rough materials.
Alternatives: If you have concerns about using isopropyl alcohol, you can opt for using mild dish soap or eyeglass cleaning solutions. These are generally safe and effective for cleaning glasses.
In summary, using 70% isopropyl alcohol occasionally and with care should not cause significant damage to your glasses. However, if you're unsure or have special coatings on your lenses, it's always best to consult your optician or the manufacturer for specific cleaning recommendations.
