I have the same problem on clear bottles, do you think bleach will work there too?

If the stains are on the inside it's probably algae if the bottles were not washed out straight after use. Fill about quarter full with sand, add to half way with water and give a "cocktail" shake. Rinse with clean water. Make a mental note not to leave them again!

Its not algae, Its on the outside, and it looks like grease. But washing doesn't seem to take it all off.

i doubt its grease, if its where the bottles rub against your cages and you have aluminium cages its probably aluminium oxide.
your chances of getting that off are pretty low since its the second hardest thing on earth |

aluminium oxide is very tough stuff, you might get it off with caustic soda (which is a bit nasty to use) but other than that you would have to sand you bottles back which might make them look a bit messy
perhaps your best option is to buy some darker bottles |

Buy more expensive bottle cages...
The cheapy cages are normally painted aluminium - the paint wears off and the aluminium stains your bottle.
The more expensive cages are anodized (a much harder coating) - eventually the coating peels off but at least is doesn't stain your bottle.... |

yeah well no bike shop is going to hand over a pair of really good cages for nothing....
there is nto much you can do except get some different cages or darker bottles. You can't get rid of aluminium oxide from the cages since it forms instantly when polished aluminium is exposed to air and forms a hard protective layer on the surface that stops them corroding further |

Darker bottles is not really the answer. They stain as well. I use sunlight liquid and those green pot sponges and that cleans them quite nicely. I have bottles that I use for more than two years now and just clean them after every use.

well if you want to go all the way you can pay hundreds of dollars for carbon fibre cages
but good cages cost like $30-40 AUS, or you can get plastic cages which won't stain |
