Most later model DSLR cameras now come with image sensors that have a filter with a tin oxide coating. The methanol in cleaners used to clean filters on the older style cameras can etch this type of coating. This new cleaning kit from American Recorder uses an ethanol cleaning formula that will not etch image sensor filters that have a tin oxide coating. This cleaning formula is also non-hygroscopic so that it will not leave a residue on the sensor filter. This cleaner is safe to use on the older style image sensor filters.
