Reply To: How to kasher sinks for Pesach

I have always used Mayim Roschin from a Kli Rishon (many of them in fact.) But I just learned it inside in the M”B, and it is not so pashut. When I pour a hot chicken soup pot into a smaller pot on Erev Shabbos, sometimes a hot kneidel or other ‘Davar Gush’ could fall into the sink. The same happens when straining noodles, some hot noodles miss the strainer and fall into the sink.

According to many, a Davar Gush does not lose it’s heat, and therefore it is not called Eirui Kli Rishon, but Kli Rishon itself. As such, it would require more than just pouring water onto the sink. It would require the addition of a hot rock to bounce the water off of. This additional step (which I was considering being machmar for,) seems like too much of a hassle to attempt. An immersion heater, which actually boils the water inside the sink and does a genuine Hagalah, seems like an alternative worth looking into. I was curious if that service had one.

Granted, there are many kulos one could rely on here. To mention a few:

– Not everyone agrees that a solid food inside a Kli Rishon does not lose any heat when tranferred to another Kli.

– That is not ‘Rov Tashmisho’ of the sink

– It won’t be a Ben Yomo when the kashering will be done.

Some people mentioned that they saw this ad on poles in flatbush/midwood. But no one remembered the phone number yet.
