Removing Hot Mug Marks on a French Polished Grand Piano

I guess this qualifies as a Repair . . . . .

A friend of mine recently had the decorators in, and despite covering his 1930s Broadwood Rosewood Piano,

it got Marked by a Hot Coffee Mug . . . .

The French Polisher called in to fix it used a rather ALARMING Technique . . . . . of
applying a layer of methylated spirits over the affected area and setting fire to it (repeatedly).

No additional French polishing required, just furniture polish and plenty of elbow grease.

A great result - the whole process took about 20 minutes - and not too expensive either.

I would guess that this should be done progressively, by degrees (extinguishing the fire) -

and repeat 'til mark is gone . .

Obviously - this is one of those "proceed at your own risk" operations . . . .

But it does give you somewhere to go if you are feeling Brave/Confident. :lol:

The important thing is that It IS do-able - but get a Pro in if you are not confident . . . 8)

I hope he charged the decorators for the cost of the repair. :(

We get heat marks on our kitchen table if people put hot things down without putting anything underneath. I don’t know if we want to try that repair technique, though— lighting it on fire?!? 8O
