Do most people tend to use pastry.brushes as flux brushes? The flux brushes I get from the plumbers merchants dont last long

I've had the same small laco flux pot with brush on the lid for about 3/4 years, just keep topping it up with flux from a big tub. I don't clean fittings with flux after soldering like some of the lads at work do so maybe that's why it's lasted so long

this fad for 'cleaning up' the joints after soldering by brushing flux on em drives me crazy.

I maybe wrong but doesnt it help clean the joint up before you clean it ?

clean yes..
with flux ? no, it only goes green and eats away at the pipe over time.

solder, swipe your finger around the joint, clean up with a wet cloth and done.
why does a joint need more flux after its soldered ?

I always used to use my finger to apply flux, stopped doing that after reading how nasty flux is, I now try to not breathe the fumes in too but not always possible...
Not sure of the brand, but I just use the couple of freebie brushes I blag off the merchant whenever I buy solder ;)
They almost always last a roll, only time they don't is when I've had a spell of not soldering and they're left dirty and unused for too long, the bristles just clump up and drop off if left fluxed up too long.

I do the same. My flux and brush stay clean and the small tub is a good size for the tool box. As a couple of other people have mentioned, this pasting flux all over the outside of the fitting drives me crazy too. About half the apprentices at the college I work in do this and I wonder where the idea started? It really winds me up much more than it should, especially when a nice tub of flux is full of bits of melted brush which can cause a bad joint if you don't notice it before you assemble the fitting.

Stop it!

Whats wrong with cleaning the pipe up with it after soldering? It makes it bright and shiny, looks a good job when finished. I always do it and then wipe the pipe over with a damp cloth.

Plumb center flux brushes I use, PTS ones are rubish n don't last long. I clean the fitting with flux afterwards then wipe clean with a damp cloth. Applying more flux to the join helps the solder run around the joint also. I use end feed fittings.

Never have green flux marks left on my pipe

So you wipe the fitting with your flux brush after soldering before the solder has set to aid the solder running? I used to do this but was burning the bristles on the flux brush

I do it and very rarely get leaks, the Plumb center brushes are good quality and last long enough and I use them very day.

Your all doing it wrong have a search on ebay for hog hair brushes, 1 brush will last months and thats even applying flux to fitting straight after soldering.

I haven't seen it in any of the soldering guides I've read and I don't feel the need to do it myself but suppose the end result is the most important thing. If it's sound and neat then I suppose it doesn't matter how you get there. I don't like doing it though. A waste of flux in my opinion and I get good results without doing that so I'm not about to start.
