My alum. intake manifold has normal dirt and stains on it from over 32,000 miles of riding . Does anyone know a simple way of cleaning these stains off by some means other than Gunking or scrubbing then hosing off that would normaly have to be done outside in better weather? I'm just wondering if there is some chemical mixture or cleaner that can be brushed on and wiped off without making a big mess ?
Thanks,
Jack
