I had high hopes for this product but might as well use water as it cleaned nothing. I had some traces of grease from nearby stove on my near new blinds and not only did this product not remove anything but any attempt to then wipe off small areas of grease met with a great black smear. Other marks also did not get removed. Totally angry with the ability of this product. Water would do just as good if wiping off dust is all its supposed to do.
