Hot cup mark on table

[Blackswanwood]

Any suggestions for how to make good a hot cup ring that has been left on a table?

A neighbour has asked me - he’s been told to use a damp towel and an iron which sound odd to me.

Thanks in anticipation of any guidance.

I can't help you, I'm afraid, but anyone who can will probably want to know what wood it is and what the finish is.

Hmm. That might work. When I've inadvertently 'dinged' my instruments, I use a damp towel and a cordless iron and most times it removes the dents.

I'm not sure how it would work on a stain.

My first port of call would be methylated spirit

I read somewhere a while ago so please don’t act on this, that the ring is caused by moisture getting under the surface and into the shellac and a warmish iron on top of a dry absorbent cloth was the way to go. But as said someone with some knowledge will be along soon.

Thanks guys. It’s Rubberwood and I think it’s a lacquer finish.

I’ll pass the suggestions and a suitable caveat on and let him get on with it!

Seems the iron and cloth method is well tried...

AI Overview

You can remove a white heat mark from a rubberwood table by using a hairdryer or a clothes iron over a dry cloth to gently evaporate the moisture trapped in the table's finish. [1, 2]
The white hazy ring is not a deep stain; it is just microscopic moisture trapped under the clear finish because the heat caused the wood pores to expand and then trap vapor as it cooled. [1, 2]

---

Method 1: The Hairdryer (Easiest and Safest)

1. • Clean the surface to remove any dust or crumbs.
   • Set your hairdryer to its lowest or medium heat setting (not the cool setting).
   • Hold the nozzle about 2 to 3 inches away from the white mark.
   • Keep the hairdryer moving constantly in a side-to-side or circular motion over the stain.
   • Check the mark every 30 seconds. Stop as soon as the white cloudiness disappears, then let the wood cool and apply a standard wood polish. [1, 2, 3]

---

Method 2: The Iron and Cloth Method (For Stubborn Marks)

1. • Ensure your iron has no water inside and the steam function is completely turned off.
   • Set the iron to a low-to-medium warm setting.
   • Place a clean, dry, thin cotton cloth or tea towel over the white mug mark.
   • Place the warm iron on top of the cloth and keep it continuously moving over the spot.
   • Lift the cloth every 10 to 15 seconds to check your progress. Do not leave the iron resting in one place, or it can scorch the cloth or damage the table finish.
   • Once the white ring fades, buff the area with a nourishing wood polish or lemon oil. [1, 2, 3, 4, 5, 6, 7]

Doing a search for removing such marks also brought up some products such as Rustin's Ring Remover and some others. Used 'how to remove a hot mug mark from a rubberwood table' and got the above...

Didnt the old guys used to put some kind of flammable liquid on and set fire to it? Presumably to draw any trapped moisture out

i watched a french polisher spread meths onto a lacquered piano set fire to it and polish it off. quite a skill as i think if i did it there would be a pile of ashes and some metal left (this was for white water rings)

Meths...

 

[Jonathan]

Having worked with quite a few polishers over the years my guess the meths could have had something else mixed with it that was top secret passed down from the masters.
I know for a fact they have things ready to play with when people are watching, similar to the secrets in F1 engineering.
I helped a dear old friend/polisher close up his shop and helped skip 100s of jam jars of concoctions. Only he knew what was in them and what to do with them.

I think if I suggest setting light to anything his wife may go up in smoke - there’s a bit of marital friction over whose mug caused the issue!

I’ve suggested all of the above (at his own risk) and also pointed him to a product from Liberon called Ring Remover which Restorate recommended.

Thanks for the suggestions and advice.

He has my sympathies
