I would like to stand up for the kavod hatorah of Rabbi Blumenkrantz, zatzal. Rabbi Blumenkrantz was respected as a Talmid Chacham and a posek. While he is often perceived as a ‘machmir’, he explained that his thinking was that if you can get the product available without any problems or any chashash chometz, then why bother with the ones that have problems and may contain chometz. I would conjecture that the amount of time he spent researching all the items in the book are not compensated by the income from the sales of the book. But that is not the point.
I use the book only after consulting with my rav regarding which items i need to find kosher for pesach versions of. My rav holds that Bounty is fine if you discard the first three sheets, and that is what I do. The same goes for the shampoo, detergent, and deodorant lists. My suggestion is that you do the same, and depending on the rav, you may find that you are not running around KRM or The Pom with the book for only 1 or 2 products.
If you notice Rabbi David Feinstein writes in his approbation that he too uses the book for “any products that he needs” to look up. He does not say that he only uses products mentioned as KLP in the book. I am sure he uses many other products, which are, in his opinion, okay for pesach without any problems.
I think this puts to rest any sholom bayis issues. People should consult their rabbanim about general pesach questions just as they do all year long for their other shaylos.
CKV to all.
