Renovating Wood Hatch Coamings Stained From Water

[BlowingOldBoots]

When the teak of the hatch coaming has been heavily stained by water leaking in through old hatch mounting holes (which had been filled with mastic that had since shrunk), don't waste time sanding the stains away. The stains penetrate deep into the wood and one would be better (and faster) making new coamings even when the wood is sound on the original coaming.

Have you tried Oxalic on it?
It is excellent for bleaching and restoring marked or faded wood.

I haven't tried that but thanks for the suggestion. I will order some up and give it a go.

Many Thanks,

I found a place in Glasgow who sell good quality O acid in 0.5kg tubs
Smith and Rogers, Elliot St, since 1877.
Their main buisness is varnishes and wood finnishing products.
Worth a visit because it is like walking into another century when you enter.
