Homemade bicycle remedies
A nice one is the use of with-vinegar for rust removal. Works quite nicely on bolts and rusted bits.
Not personally tried, but some people reccomend the use of furnitre polish to wax your bike, to create a sort of a coat able to protect from water and moisture.
WD40 to simply remove old stickers and &quot;unknown&quot; dirt on the bike frame.
