Ive tried several products and nothing seems to get the road grim off, any suggestions? Stock pipe

 

just get some mothers aluminum polish. just like waxing. comes out nice.

 

I Like NevrDull,Its like a cotton base u tear of whatcha need,you let it dull up,Polish it.....Werks awsome....
p.s. i used to werk for Tubing Company that specialized in all Metals,Stainless,Aluminium,Brass,Titainium,Copper etc.ETC.etc......We used to use it on everything & I still do.......

 

Depends on what kind of dirt/grime you got on there. If it's chain wax/lube & dirt, try a toothbrush and some powdered laundry detergent mixed with water. If it's oxidation then use what's been recommended above.

 

Neverdull will Remove ChainWax,Road Tar,Rust spots ,most exhuast Blue-ing,and just bout anything else.....
