I pulled off my Staintunes tonight. I have had them two riding seasons now, and this summer will be the third. I wiped the road grime off them and then took the tar spots off with some solvent. I was very happy to see that there was not one speck of rust of corrosion. I'll buff them with some Blue Job and put them back on, just like new. Now I'm glad I went for the stainless steel.
