A bit ago someone asked about cleaning engine cases, I don't think anyone answered, so here's my opinion. What I've used with some success is a spray aluminum cleaner from NAPA although the sprayer sucks and stops working after the first time you use it. Eagle One Mag etching cleaner is possibly the same thing, basically a phosphoric acid solution. Spray it on and moosh it around with a small stainless or brass bristle brush and rinse with lots of water. NOTE: don't get this on anything shiny like chrome or polished aluminum, it will etch it. It can be pretty nasty stuff, so don't use it for eyedrops or drink it or anything. A friend of mine swears by steel wool and WD-40, but I haven't tried it. A very fine wire wheel on the end of a die grinder is helpful, but you have to have a light touch and not leave swirl marks, what you're looking for is a uniform finish, and not scratch the casting. Someone on the Laverda list just posted this website for neat little brushes, and although they're in Australia you could probably find something similar in the US. http://www.machinerycleanery.com/ There's basically no easy way to do this, it takes lots of elbow grease, patience and beer, mostly beer. Try several things and see what works for you. John Prusnek Hi Folks, Found some interesting search results for cleaning brushes: |
2. Bore brushes come in SS for shotguns and rifles etc. and might
just fit nicely between fins etc.
3. the company at www.gordonbrush.com seem to do a wide range of
products in this area of specialty and perhaps something like the Aussie
product.
Best wishes to all.
