"Dirty Tubes"

[wolfie]

OK, not long acquired another SR4, done the usual things to the topsides, cleaned etc, how ever today Saturday, i turned it over to start on the hull, and YUK..... lots of seriously brown staining from sitting on a mooring on the Avon / Bristol channel area, The mud has seriously stained both the glass and the hypalon, especially where the barnacles were still attached, these knocked / wiped off easily enough, but the staining is horrendous, have tried rib revive etc, no joy, have test "sanded" a small patch of the hull and it does come off, any suggestions that may help, or is it a Q of wet and dry and polish ?

Bleach will get the stuff off the hull.
Have you tried TFR (traffic film remover) on the tubes?

One option I've seen if it is bad is to put fresh hypalon triangular strips to the rear under side of the tubes to cover where a boat has been on a mooring and got barnacle marked. You can't really clean it off, and it's far better than retubing!

It also offers protection for the rear section that is most frequently in the water.

Have you tried Y10 gel?

Or "Chine Shine"?

Both oxalic acid based cleaners. Good for removing some staining.
