Just took 5th wheel out of storage. Underside (white) has stains . Tried simple green, oxy clean, bleach dawn, soap etc. Any suggestions to completely remove stains.
Dawn dish soap and baking soda in solution. Spray on underside and roll up for 30 minutes. Deploy awning and scrub with remainder of solution. Works quite well.
