When I discarded my Christmas tree which had been sitting in a stand holding water atop a small carpet on my oak tile floor, I was horrified to discover that a 3 foot ring of moister had collected and mildewed there under the carpet. Although I had done this same set-up for many years without problems, disaster struck this year and I don't know how to get the discoration off. The tiles are now dry by way of a heater for 36 hours and I had no trouble cleaning off the mildew. What I have are darkened oak tiles in a three foot ring. The tiles have never been varnished or otherwise coated except with products like Pledge. Help, please. What can I do myself?
