I live in New England. My white vinyl siding has developed small black spots on it. They are about the size of a pin head and are raised. You can scrape the raised portion off and they feel soft but they leave behind a black spot. Nothing seems to remove them. I have tried several cleaners, scrubbing and pressure washing. They are not a mold as bleach products have no effect. Someone said it may be sap from a nearby pine tree but I tried a bug and tar remover with no luck. I was also told that it may be spores from the mulch spread in the flower bed below. Any suggestions?
