Remove hair spray on plastic lenses with Sterilium

Since I am a wearer of glasses even since I think, I have tried with various remedies to remove stubborn stains (including just hair spray) from my glasses. Sterilium works best for this; this is a hand sanitizer. Are in the pharmacy and in the hospital :-)

Simply put some Sterilium on toilet paper or Zewa, gently rub the glasses with it. Then rinse glasses with Pril and warm water. Helps 100%!

By the way; my lenses are ultra-high-reflection, have a scratch-resistant layer etc. So only the finest. And even then you can safely wipe it off. My optician has confirmed to me that it does not harm the glasses.
