Black speckles on motorhome

[Doug Domm]

My motorhome was parked near trees for a period of time and is covered with black speckles. Not sticky like sap though. Anyhow I tried every cleaner in the shop ranging from mild to wear rubber gloves take your skin off and nothing would touch it. Alas, my daughter suggested mr.clean magic eraser extra strength and that stuff was almost effortless. Just passing my discovery along.
