    Default Dirty stripes on hull from. aluminium toe rail

    I'm frustrated by the dirty lines I have all down my top sides which seem to be as a result of my aluminium toe rail. Does anyone know of some marvellous magic formulation I can use to seal the aluminium to minimise this effect? The ongoing cleaning regime is driving me crazy as it just doesn't stay clean for long. Thanks

    We don't have aluminium toe rails but we get plenty of black marks down the topsides. A product called 'Black Streak Remover' has been very effective.

    +1 on the black streak remover. Works best above 10 deg c.

    Seveal past threads on this subject here and on other forums.

    Concensus seems to be that it isn't the aluminium toe rail (as hinted at by Vyv Cox as he does not have an sluminium toe rail but still gets lines) but the join between hull and deck (just below the toe rail) which accumulates dirt. Give this a thorough clean with a stiff brush or power washer. I did this on mine and no more black lines down the topsides.

    a lot of the streaking seems to be caused by the difference in the aluminium and the screws/fixings used(steel)

    No toe rail and deck scuppers are fitted, no water down the hull.

    I have this problem every winter on my Jeanneau SO45.1. The streaks line up with the oval holes in the aluminium toe-rail so on mine at least I think it's the anodising on the aluminium toe-rail coming off. I've not found the "Black Streak Remover" that effectrive, I use a strong solution of Vanish Oxy-Action in fairly warm water, a clean sponge and lots of elbow-grease.

    What does seem to help is the polish I use. As part of the winter lay-up I wash and polish the topsides with Starbrite marine polish with PTFE. I give them two coats of polish and that does seem to make the black stripes much easier to remove next spring.
    Let's make better mistakes tomorrow
