Cleaning clear frame glasses isn't different from cleaning any other eyewear frame. However, clear frames
do stand out more easily, so it's worth putting a bit more time in keeping them squeaky clean.
Step 1: Wash them under lukewarm (never use hot water) water. Use your hand to rub off debris or any smudges.
Step 2: Clean the lenses using just a drop of dish soap, or a lens cleaning solution.
Step 3: Work the soap/solution gently into the lens and frame. Don't forget to put some work on the nose pads, as they tend to get dirty fast.
Step 4: Wash the glasses again under lukewarm water to get rid of the soap.
Step:5: Dry your clear frame glasses, preferably with a microfiber cloth (make sure it's clean).
