You don't need to use your fingers to get the dish soap off just use running water. You should be looking at perfectly clean lenses with a few drops of water on them. If there's any grease or other spots, repeat steps 2 and 3.Use a microfiber cloth to gently clean off remaining water drops. Use light touches there might be small pieces of dirt on the cloth and if you rub it too hard, they might scratch the lenses. The microfiber cloth leaves no fluff, so your glasses should be perfectly clean.
