I would under no circumstance use WD40 on anything rubber. It has a petroleum base like kerosene which will degrade anything rubber. I use Camco Slide Seal lubricate. It goes on as a foam so you know where to spray it. When the foam dries it leave the rubber soft and supple.
+1.
I use the foam seal lubricant kinda as a cleaner when I wipe it on....but I'm only cleaning off a little light surface dirt, not trying to remove mold. I am pretty sure Home Depot has a product for mold eradication...you might check with them to see whats in it and what surfaces it is safe on. Or just use Dawn and some elbow grease, as previously described, and maybe keep an eye on the area.
