Mei Klaf/Spray Klaf: A Visit with Rav Friedlander shlit"a

HaRav Michael Tzadok Elkohen and i visited with R' Friedlander shlit"a at the beis hora'ah in jerusalem today. armed with a bottle of mei klaf, a can of spray klaf, a mezuzah psulah that had been treated with spray klaf and a copy of the ishur for spray klaf from HaRav Yaakov Meir Shtern shlit"a (thank you, R' Alberto).

1. the bottle of spray klaf was presented along with the ishur. it was pointed out by Rav Friedlander first and foremost that the ishur listed on the can of spray klaf (by Rav MOSHE Shtern) is from two different rabbanim (printed ishur provided by R' Alberto in a previous post was given by Rav YAAKOV MEIR Shtern).

2. the mezuzah that had been treated with spray klaf was shown to R' Friedlander along with with a hands-on demonstration of how easily the otiyot were smudged from a simple negiya with a finger (the original tish-tush of otiyot happened simply from rolling the mezuzah). Rav Friedlander and those present were visibly dismayed. Rav Michael Tzadok next sprayed an index card with the spray klaf. after it had dried R' Friedlander rubbed his finger over the treated area and mentioned that it felt like wax and that there was obviously an issue of chatziza present.

3. Rav Friedlander said that Rav Yaakov Meir Shtern (from the ishur posted by R' Alberto) should be notified about this issue

4. i presented a bottle of mei klaf  produced by the Dyo Nahari company (clear plastic bottle with a blue brand label), asking about the issue of chatzitza with this version of the product. R' Friedlander said that there is absolutely no problem with mei klaf and that there is no issue with chatzitza whatsoever since the liquid is totally absorbed into the klaf.

In summary according to Rav Friedlander's psak:
A) SPRAY KLAF poses a concrete issue of chatzitza and Rav Yaakov Meir Shtern must be contacted

B) MEI KLAF is mutar for use; no issue of chatzitza at all.

i would like to thank R' Michael Tzadok Elkohen for accompanying me to visit Rav Friedlander and may the oilam of the heilige STAM FORUM and all sofrim mus'machim abroad find yishuv hadaas and mishivas nafesh on this issue. sh'koiyach.


I stumbled across a sofer here in Eretz Yisroel, who claims to be checking his mezuzos 2 and 3 times by himself, but doesnt not do a computer check, or check by someone else. Should he be bought from? Is this ok lechatchila?
