Works fine for me! I use ezest or ms 70.

(Thats for my silver coins)

What are you dipping?

It is a diluted acid. I believe it actualy strips off the surface of the metal. Thats why a coin begins to look dull and lose lustre after repeated dipping. If you are going to use it dilute it even more with distilled water and dip for only seconds. Make sure you neutralize the surface of the coin with acetone after dipping or the acid will continue to be active and will leave ugly black spots and unwated dip residue over time.

Rinse the coin with WATER...acetone will quickly evaporate, leaving the acid on the coin!!!

Oh, ya, I forgot that step. Thanks. Use distilled water to rinse. Tap water will leave chemicals/minerals in the water on the surface of the coin.

This will depend on the results. Does anyone have before & after pictures.

Russ,

What was the difference in the grades before and after? Value also.

PR66CAM to PR69CAM. Paid $60, sold for $450. I picked off three of them on TT, all were covered in flip haze and all were 66CAM. All came out beautifully. One stayed at 66CAM, one graded 68CAM, and then the 69CAM pictured.

I'd dilute it to about 25% solution and dip quickly, only a second. Just a quick in and out using tongs on the edges.

You can always dip it a second time if needed. I rarely ever use the stuff. If I do, I use acetone first to see if that cleans up what you are after, only then would I go to EzEst, rinse quickly and follow that with acetone again.

MS70 is much more forgiving and easy to work with and you can use a Q-Tip on selected areas of the coin if needed, just be gentle.

I'd try a test coin first till you get the hang of it. EzEst can ruin a coin with nice original surfaces if you don't know what you are doing.

Just be careful.

I have had success with it, but only on a few occasions where it was a last resort. I don't have any pics, but I did turn a BB into an MS65 on a fairly expensive coin. Only once have I had those sorts of results.

MS70 is basically a soap (actually a golf ball cleaner as I've posted before). Used with a Q-Tip gently, it will take off light toning and crud/haze/grit without any harm at all. E-Z-Est is an acid and will strip a surface from the coin . . .I totally concur that it is a lot more aggressive than MS70.

One is just Ivory Soap on steroids . . . the other is an acid and repeated use will kill luster.

MS70 is the best on silver and warnicks . . . and turns almost any copper purple or blue. Rinse and stabilize like the pros tell you here and you will be fine . . .

it works very, very well. Don't overdip though

Goo Gone is the best.

Edited because it's two words and not one...

Hey, since it appears that the Doctor's offices are open: What is the least invasive way to take fingerprints off a proof coin (silver). I know that a traditional acid dip (EZest) will do the trick, but was wondering if something less 'destructive' would work: Acetone? Koinsolv? MS70?

Thanks for your help, oh learned men of science....!

If the fingerprint is fresh acetone should take it off. If it's older you'll need to use a detergent or acid dip.
