Is Cynoff EC safe to use on vinyl siding?
Using the recommended application with a fogger and mixed with light mineral oil.
Cynoff EC mixed with oil can cause staining on older siding or siding that is in need of paint. Homes with newer siding or freshly painted siding should be fine. Just to be safe, you should always test small inconspicous areas to be sure staining will not occur.
