for pesach?
If only a little hits the sink from the kashering pot, it could take hours to kasher the sink. How do you do it and how long does it take you?
Also how do you kasher the faucet and how long does it take you?

eta, I have 2 inches between the cabinet and the top of the faucet. How do I kasher that top rounded part of faucet?

We use a blowtorch for most of the sink. Takes under 10 minutes. I use the kashering pot for the faucet, but that goes pretty quickly. (It's not like I can pour on the underside of the faucet...)

rabbi told us to be careful but to flick water at undersurface of faucet also.

Blowtorch safe for sink?

rabbi explained that only the first amount of water that hits the sink, kashers that small area, he said size of nickel? So of have to redo over and over size of nickel it will take a long time?

I use an electric kettle. Water is still boiling when I pour. Only the area touched by the water directly kashers, and it's small, but it only takes a few minutes to cover the entire sink and faucet.

I dont think many rabbis hold this way.
We pour the boiled water all o er the sink. Thats it. Takes about 30 seconds.

Blowtorch is perfectly safe on a stainless steel sink. (Not faucet, many faucets are not real metal, just with a thin metal veneer. Found out the hard way.)

5:40 starts sinks. Shows how to actually do it.

thanks this helps except I dont understand what he said about arc hitting a vertical area, it doesnt matter for kashering but I'm just wondering?

Ceramic sink.

Scrub it out thoroughly.
Pout boiling water everywhere, because, why not?
Insert sink liner.

Job done.

Water backed up through the bottom of the liner and then it's a kashrus problem.

I think this is what he meant that it's only a small area so have to keep redoing it. but star K video shows him using a continuous stream of water. So is it as long as water doesn't stop it can still kasher even a large area? or is it only the first stream of water that hits, kashers?

We use 2 huge metal kashering urns that are brought to a boil simultaneously. It takes a while for the water to boil up. We put towels on the counter behind the sink and on the floor in front of the sink while it's boiling, and we also rest during that time. : )
Dh also heats up a stone in a holder at the same time. He holds that the added heat is necessary, if I don't want to use a sink insert on pesach.
It takes 2 of those urns for each sink. Takes a total of 120 seconds for dh to kasher a sink; holding the boiling stone on its long stick holder over the sink, and pouring the boiling water, as he moves the stone and pours the water all around.
Then we fill and boil up the 2 urns again. And kasher the next sink.
Done.

I added information about a heated stone that dh uses, above.
Yes just pour continuously all around with 2 huge ready boiling urns for each sink to cover whole surface.
