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've always used my fingers, doesnt waste flux and the brush's are rubbish and end up lost broken or full of dust,
 
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.
 
Tbh i've never used a brush for flux. Always my finger or the end of the solder and i'm still alive and have silky smooth skin so the wife says 😉

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
 
the only thing I go in plumb centre for...brushes and there jet blue paste
 
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.
 
Do most people wipe fittings with flux after soldering as its still setting?

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.
