The best has less water but costs more. 91% grade is still quite inexpensive via Wal-Mart. I too find Ronsonol (Naphtha in USA) best on blade cleaning. Alcohol works well on the lens surfaces but I will usually use 50-50% mixture of hydrogen peroxide & household ammonia to 1st clean crud off the glass surfaces (haze, fungus).
