• I am playing with Wilko Soda now for second day on two frames, first time.
    Fuji Track - seatpost is almost dissolved, few more tries and it will be OK. Second frame - Specialized Langster - no matter how much I pour in, seatpost doesn't dissolve. Magnet doesn't work on it so it must be aluminium. Any ideas? Increase ratio of soda against water?
