We all know what a nuscience spiders are for leaving their mess all over the frames n sills, when caught soon enough it comes off pretty easy with the wfp, but if caught late the top half cleans off but sometimes leaves a lighter brown mark which just will not come off, even if you try to scratch off with your finger nails(urgh)
i know its suppose to be acidic but is there any products you guys n gals have used that cleans it off as good as new?
have a couple of nice properties that are starting to show these marks more n more on the white frames n sills and am getting worried the custies may think my standards are slipping..........
what advice do you have?
