Gold coin with red rust spots

Greeting SS,

I just wonder whether red rust spot on gold coin can be cleaned/removed?
is this 'the milk spot' on gold coins?

Copper spot.. NGC can remove it by 'baking' the coin (based on what I've heard, may not be accurate).. but don;t try this at home lol!

 

I sent two gold pandas with red spots to ncs/ngc. The two became ms68 gold spot free.
;-)

 

excellent!
thank you guys

 

I had a Gold Panda last week with a small red spot on the rim,this coin had come straight out of a OMP,i touched it up with some acetone and it disappeared,,had a time trying to find nail polsh remover in the house that actually had acetone as an ingredient as some are acetone free

 

Acetone...I thought that resin will make the silver color faded? eps from the nail polish remover.

my mrs got plenty if this works well

 

If the colour fade, you may want to get it check if it's the real thing

 

I sent 5 pandas in with brown/red spots. One had an amazingly large brown blob on the head.

All came back MS69 and all spot free.

I would not do it myself if the coin is numismatic, NCS does it for a pretty cheap/fair price imo.

If it is a bullion bar I would try acetone or something since Gold is pretty stable unlike silver.

 

Boiling it in washing soda works too....

 

Thank you all for sharing different methods of removing the red spot on the gold. I have tried many methods but I failed. Thank you.
