Simple Question: Brush and Cleaner

coil type condensing heat exchangers I like to use a stiff hand brush, some guys get nylon brushes that you would put on a power tool like a drill as well. if its stainless steel you can use clean F-steel from axiom. the coil type from HTP and most brands are really tight between the coils and you need to make sure you are NOT packing the products of combustion down into those gaps, they make some tools to clean between those gaps, you can use a card, or something stiff enough to get between the gap without being weak enough to snap off in there. Vac out all the big stuff, scrape out the gaps so they are nice and open (all around too!) spray on the cleaner, make the heat exchanger nice and shiny and flush out with water. You want to also clean out the condensate trap at the end of this and flush out the heat exchanger with water one more time, make sure the trap is clean, and water flows nicely out of the heat exchanger, into the trap, and out to drain. Depending on what kind of issues you run into along the way some of these steps may change slightly, the goal should always be to make it look brand new but that can be hard!

If there are refractory pieces use caution to not get them wet! if you see cracks or damage on refractory, igniter, flame sensor, gaskets this is also the time to get those parts to replace them

( I never used this site no idea about it, but this hand brush works for me for the big stuff)

some guys use a new clean toilet brush which also works pretty good!

I don't really have a recomendation for spinny brushes, I've used some from the hardware store, and I see a bunch of assortments on amazon, the ones that are sort of shaped like a toilet brush are fine, round ones are ok too
