Couple of facts.....
Mr Sheen original contains silicone, so it sort of sticks on the frame /parts for a bit. You get the bike dirty, the crud falls off easy with soap and water (including on wet mucky days - the spray keeps the build up down). It also cuts through grease, removes oil marks, and easily cuts through brake residues. Don't tell Mr Sheen though, it's great, as they will charge a bomb for a bike specific polish ! Their scented or other ones don't work as well as the bog standard original FACT !!!.
For an extra polish, the bikes get a bit of Autoglym Super Resin once in a while ! (Not for Matt Carbon - stick to Mr Sheen).
