I am looking for some products to help clean my aluminum horse trailer. One product to use on the aluminum part (silver) and one product to use on the white paint. My trailer is parked under a sap tree so green sap sticks to my trailer which the pressure washer can't get it all off completely. Here is some pictures of what my trailer is. Any advice is appreciated!

Go to your nearest and best AutoZone type store. Find a knowledgeable employee and ask. Also, invest $40 in a polisher from Walmart. It's electric and still uses a lot of elbow grease but the results are worth it. Be sure to apply a clearcoat after you finish waxing and polishing.
