Hi Guys, Just posted a quick video response on how to remove milk spots from coins if anyone is a fanatic about their maples [youtube]http://www.youtube.com/watch?v=9HIZGI7ZLKk[/youtube] Cheers, Dan
It is caused by a rare form of Maple Leaf blight spot. I hit mine with carabaryl and pyrethrum... waiting to see if the leaves drop off Good work with the eraser ,Dan!
Yeah, i think it has something to do with moisture & detergent.. i cleaned some at one stage and I made it worse.
Really? what colour is it? the harder they are the more abrasive they are, the softest is pink, then white, then red, then gray.. just use a normal white soft plastic eraser. I even use an eraser to buff small scuffs out of gold. Also don't work a frosted section too hard, you can buff the frosting out!
it might just be residue, sort of looks like smearing, maybe the type of rubber?.. anyway maybe try give it a wipe with some cloudy ammonia & detergent, or rinse with soapy water. I guess you also have to be careful not to pick up any grit on the end of your eraser, something to be wary of if you have a real dirty coin you might just end up spreading the grit around and scratching the coin. something to be cautious of.
Just tried it on some maples. It definately reduces the milk spots! How'd you come up with that idea Dan? That's some lateral thinking!
i stubbled across it when i had to fix a small mark and a few scuffs on an old gold coin.. don't know what made me think of it, i was probably hunting though my draws and it looked like a better tool then the scissors.
Ok, i've done some testing and I am now pretty positive that any marks left on coins are because the eraser is picking up dirt off the surface of the coin and you then rub it all over the surface. If you use a good quality soft eraser, keep checking the end make sure you don't have any dirt and no black bits on the end of your eraser you shouldn't have any issues. If anyone wants to confirm this that would be great.. hobo, if you are willing.. with a nice clean soft eraser try working that coin again, you might find it cleans up.
Adding a small amount of dish washing liquid (a detergent) will give the cloudy ammonia a power boost.
