 +====== Cleaning the Alloy bits of your bike & keeping it looking like new ======
 +
 +From the Vintage Japanese list:
 +
 +A while ago, Chris posted a message asking about alternative methods
 +for cleaning all the crud of aluminium engine parts
 +
 +....here'​s one to try...
 + Grab yourself a large saucepan, big enough for the item to be completely
 +submerged, fill up with water and cut up 2 or 3 lemons in small
 +pieces and put into the water. Bring to the boil and then turn the heat right down
 +and simmer for up to an hour. 
 +
 +I tried this on my fuel petcock and it cleaned all the crud off
 +in less than 15 minutes. It almost looked like it was bead blasted !
 +! ! Well almost....When you pull it out of the water, your fingers will get
 +smudged with grey "​slime"​.....just rinse completely and very thoroughly and then
 +use a commercial ¬†aluminium cleaner and you will end up with a mirror like
 +finish....try it on a spare scrap part, you will be amazed how well
 +this works.
 +
 +
 +And to protect it::: (from the Brit Iron list)
 +
 +About aluminum engines: many OEM's do not paint aluminum engines (or
 +components). Rather, they use a wax emulsion spray on the finished engine
 +assembly. This works well as an anti corrosion film, but can be washed off
 +with harsh solvents.
 +
 +For hobbyists like us, I found another offshoot of the aircraft business
 +that works beautifully:​ Boeshield. This product was developed by Boeing.
 +It replicates the OEM wax coating.
 +
 +Boeshield is an aerosol thinner/​lubricant/​wax in aerosol form which does a
 +wonderful job sealing and protecting clean metal surfaces. Looks good too.
 +Spray it on evenly after cleaning and thoroughly drying the engine.
 +
 + Mask pulley surfaces. Let it dry for 4 hours, then apply a second light coat.
 +The result is a durable clear finish which seems to last indefinitely. I
 +use it for SCCA 911 motors, which are always being recleaned and worked on.
 +
 +Also on motorcycles and marine engines. Gunk flushed with cold water does not
 +seem to take it off, though solvent and steam cleaning will. The good news
 +is that it is very easy to reapply and touch up.
 +
 + Does a nice job sealing ignition systems, as well. Just for grins, I sprayed one side of a new
 +aluminum Danforth anchor with it a couple of years ago. The results were so
 +good, I have now cleaned and sprayed the other side, and the rode chain.
 +
 +
 +I have seen plenty of examples of painted aluminum engines. Most are a
 +mess.Even the OEM (mostly older Japanese) clear coats fog up and lift, trapping
 +moisture under the edges.
 +
 +I think paint is OK for cast iron and steel stuff, but suggest you try
 +Boeshield for aluminum. It is available at marine stores (eg, West Marine,
 +about $15). A little goes a long way.
 +
 +Hope this helps.
 +
 +If you try any of this, I'd like to hear how you do...
