its 100 plus in texas and i goofed. i dropped a melted citronilla candle on my back padio that is a flagstone type with sandstones. how can i clean it off? my neighbor did the same thing on his driveway last year and the stain is still there. he tried a small pressure washer, but it didnt help much. i have a theory, but want to see what you all think before i make things worse. thanks all
