Installed fiberglass front door then worked hard to stain it so it looked like wood. Three months passed and I didn’t get around to sealing it (ignorance). Looked great until mold started to grow which I can’t remove with bleach or sandpaper. I need to take the whole surface down and start all over, but what shall I use? How can I restore this now very moldy door?
