I am not a dipper (I am adamantly against it as I believe it is coin cleaning and/or doctoring) but when I did my experiment I asked for proper...
IIRC that's similar to what I did, though I did not run the coin with hot water before the dip, and followed with two final distilled water...
I remember doing an experiment about 10 years ago, which I published on another forum, where I used a coin dipping solution (EZest I believe) to...
I'm no expert either but from my reading the final product of the reaction is mono-chloramine. It is in lower concentration than what is allowed...
Are you sure? If that were the case, then it would be much safer to clean our coins with alcohol than with acetone, yet no one recommends using...
Keep in mind though that chloramine is chemically active, and kills bacteria, etc through chemical reaction. I have never done an experiment to...
So what is your take-away from the CDC that is different from the EPA?
You quote "formed by mixing" but where did you see that stated? Here is an actual quote from the EPA website I linked to: Chloramines "Are most...

In clean environments, such as wafer fabs or optics manufacturing, distilled water (or de-ionized water) is used for cleaning and surface etching....
I think the rumor about acetone on copper should actually be attributed to lacquer thinner. Don't make that mistake. The main ingredient of...
That looks much better! It is still over-exposed in a few highlights but not the general over-exposure from before. Here's the pic with some...
It's very unflattering to shine a light from below such that the chin and throat of the portrait is illuminated. Think of the coin as a model, and...
Very gracious.
Well, now I feel bad about arguing for Mr BS.
Woohoo! Congrats on the new listing. The existing cud was already known as the "Triangle", so now there is a second Triangle Cud.
Check my edit...since the auction is a BIN, there is less potential conflict. Edited to add: For BIN, I guess the only potential for conflict is...
I agree, saying something negative is not automatically grounds for being sued. But doing so to influence potential buyers to lower bids, and then...
He has every right to be miffed at the OP for talking badly about his auction. There is money involved here, and potential conflicts of interest,...
I find the discussion of an active auction in really bad taste. Only time it is warranted is if the coin is an obvious counterfeit or known stolen...
