In Oct 2010, the topic of using shaving cream to clean tombstones, popped up on a list to which I subscribe <a title="mailto:rootsweb-help@rootsweb.com" href="mailto:rootsweb-help@rootsweb.com">rootsweb-help@rootsweb.com</a> and the discussion quickly became very heated.&nbsp; One side was claiming that it did not harm tombstones at all, and the other was claiming how horrible it was for tombstones.<br>

The name "Gregg Bonner" popped up in the discussion, evidently he is an academic, perhaps in chemistry, and possibly it seems that he wrote an article about it.&nbsp; So I thought I'd do a little research of my own.<br>

I found that his name pops up in connection with this [http://www.urbandictionary.com/define.php?term=hoaxer Urban Dictionary: hoaxer where he submits a definition for a Zohnerite] (it's number 5).&nbsp; I suppose someone named Zohner must have annoyed him in the past.&nbsp; I find some relevant entries by Googling for:<br>

Gregg gregg gregg... he hasn't learned how to cite his sources with inline links!&nbsp; Or perhaps he doesn't care, but we care!&nbsp; Now I have to dig.&nbsp; Way back in Jan 1996, David Chapin [http://groups.google.com/group/soc.genealogy.methods/msg/e2ddfe0f5f52d783 posts this message to soc.genealogy.methods].&nbsp; In his message, he cites an 'editorial in "Heritage Quest" by Leland K. <br>

Meitzler', so the practice has been around at least that long.&nbsp; David calls himself, "an activist AGAINST this practice, because the stearic acid in the shaving cream will dissolve MgCO3/CaCO3 that makes up typical marble stones. Since most people are not experts in the different gravestone types, as a geologist by training I suggested people stay away from shaving cream on tombstones altogether. If it's bad for a car finish, it's bad for a tombstone. I suggested using powdered inert substances, instead, such as talc, graphite, or ground limestone."<br>

I don't know about you, but I find it just a trifle odd that David would suggest using ground limestone to clean limestone.... Hello?&nbsp; Doesn't ground limestone have the [http://geology.about.com/od/scales/a/mohsscale.htm same hardness value] as limestone itself?&nbsp; Wouldn't scrubbing it on a limestone tombstone essentially remove the polish (and the limestone) just as fast as using say... a piece of limestone?&nbsp; I would think you would want to scrub a piece of limestone with a material which is softer, thus guaranteed to minimize the harm to the underlying material.&nbsp; But that's just silly me.<br>

In his posting, David, referring to Leland's article states "Mr. Meitzler was clearly referring to my Internet articles in his editorial." So David must have articles on this topic, somewhere, other than just in newsgroup postings.&nbsp; At the time of his 1996 posting, David states that he lives in Plano, Texas and gives two email addresses, one being at arco.com.&nbsp; I wonder if this means he worked at that time, for Arco the gas station company ?&nbsp; So next I Googled for:<br>

Evidently there is a David Chapin, and a David A Chapin, and together, along with Ben Weinstock they wrote this book : "[http://rcm.amazon.com/e/cm?lt1=_blank&amp;bc1=000000&amp;IS2=1&amp;bg1=FFFFFF&amp;fc1=000000&amp;lc1=0000FF&amp;t=countyh-20&amp;o=1&amp;p=8&amp;l=as1&amp;m=amazon&amp;f=ifr&amp;md=10FE9736YVPPT7A0FBG2&amp;asins=0595006663 The Road from Letichev, Vol. 1 : The History and Culture of a Forgotten Jewish Community in Eastern Europe" (2000)]&nbsp; I'm going to assume this is a father and son, but I'm not quite sure yet, which is the father and which is the son, or even if I'm right.&nbsp; Maybe it's just a mistake or extra indexing and there are really only two authors here.<br>
