Has anyone used both E-Z-Est and MS-70 coin cleaners?

If anyone has used both E-Z-Est and MS-70, which did you find worked the best or did the least damage to any of your coins?
I'm not going to try this on any coins of value but have some I can practice on.

I love MS70 on mint state coins and high AU coins with dirt or other crud and have had great results with it. Anything else, when I have played around with it looks abnormally brilliant but I suppose the coins could have had issues to begin with. Same goes for EZ-Est. Got to try it on the right coins. Id suggest some modern change to practice on. Would not suggest to use it on copper!
I have never used anything on coins except when I was a young collector (cringe). I found a few PVC rings growing on some Jefferson nickels in old flips recently and now I am wondering what exactly I should do.

Acetone soak, then use a q-tip to gently roll off(dont rub) the green crud. Will work great and preserve the coin!
It depends on the coin, its composition, and the problem I’m trying to remedy. MS70 removes many surface contaminants without removing a layer of metal that a dip will. My experience is that it does leave some mint state coins with a greasy look. I also wouldn’t use it on copper because it can induce a blue color. I like it for proofs, PL coins, or as a last resort before a dip.
Dipping also removes toning. MS70 won’t remove natural toning. If done sparingly and properly you shouldn’t be able to detect it (other than the lack of toning). Over dipping damages luster and can make a coin look lifeless. An improper dip can also leave a corrosive residue that will also look unsightly.
General thoughts:
Remove toning/tarnish: Light dip followed by full strength if necessary.
Removal of organic residue: acetone before isopropyl alcohol before MS70 before dip.
From what I’ve read if you’re going to experiment with dip try diluting it first to minimize the brightness effect.
Appreciate the feedback. This is what I like about this site. Will check back for any additional comments.

I have not used either but from what I understand MS70 is a cleaner that removes gunk, not metal. E-Zest is a dip that removes a surface layer of metal and works great at removing unwanted toning (if done right). I have read about diluted E-zest dipping to help control the reaction and prevent over-dipping.
Acetone is something I use and it is great for removing oils, PVC and some gunk. Acetone does not hurt the metal at all. But I notice that sometimes copper can have a "dry" appearance after use.
one is acid, one is base
only use on uncirculated or proof coins
@Stingray63
With e-Z-est one thing I would recommend is flash dips. That is to dip for a couple seconds, then out and into the neutralizer (the dip is active until neutralized or removed). You can dilute the dip if you want. This will allow you to look at the results / changes. Then repeat as necessary. But it also depends on what one is trying to remove. If trying to remove heavy tarnish / toning, then will need to increase the dip time as that will take more to remove. The point is this should prevent over dipping. Unless perhaps the coin has been previously over dipped or something similar.

Get the PVC off sooner and not later. PVC is active and will get harder and more difficult to remove. Could also go past point of no return without damage. At the same time I have seen PVC lay on the surface for an apparent long time and not do much. Your description of a ring doesn't sound like this though.

My experience and experiments with EZ Est is in one or two second exposure. This stuff is strong and it can alter the surface of a silver coin. Just saying.

Please don’t clean coins.

Both are good products if used properly.
MS70 on silver proofs to remove haze(ezest works here too but also removes toning) and also on uncirculated silver coins to remove surface contamination. I've found it works better than acetone.
I have also had good results with MS70 on proof cents if they are red. If you use it on brown cents they will turn blue/purple tones but it's better than leaving PVC film on them.
I have not figured out what works on nickels.
Collector, occasional seller
I like the sentiment from a general perspective, but there are cases where conservation is necessary to preserve a coin (e.g. removing dip residue, pvc residue, or other potentially unstable residue). There are also cases, when if done properly, can make a coin more valuable and liquid.
If you could find a way to encourage people to pay more for coins with ugly toning than without it, it would go a long way towards eliminating "cleaning".
Just sayin'.
I use EZest on (spotty or ugly toned)UNC dollars, franklins , and stuff On occasions . For some reason raw dollars sell better on ebay dipped than original skin. (stupid) but that's what sells better. I have never been able to use ms-70 cleaner, I am not good with it, and dont use it, An old retired dealer friend used to work wonders with ms-70 , never could figure out how he worked it so good.
I use acetone to remove organics, has no effect on metals. I have used MS70, mostly experimenting on pocket change.... It is effective and used sparingly (or diluted) will not harm the coin - leaves the luster, so no harsh surface effect. Now, if used full strength and left to sit for extended time, it may affect the surface noticeably. Cheers, RickO
One is a soap and one is an acid. Only practice and learn on pocket change. Do not work out of the container and never put used solution back into the original container.
That’s already happened to some degree. There are some people that seem believe anything with toning is worth a premium.
