Hello: Wondering how people clean their painted Crystal cabinets. Their website says to just use slightly soapy water and microfiber cloth. I had been using method all purpose natural surface cleaner and a cotton cloth (but not microfiber!) but the cabinets are slightly shiny in the spot where I have scrubbed fingerprints, etc. I don't think that just soapy water is sufficient to get the greasy fingerprint marks. Is the microfiber cloth the magic trick? Thanks in advance!
