Cleaning PCB
 

Excess flux on a board. Scrub it, but where to find a brush . Take one artists brush ,wrap with tape and it's job jobbed. I used a 15x6 mm, which tapes up to a firm 6mm brush.

I use a toothbrush, or a cut-off paintbrush, depending which way I need to scrub!

It's even easier if you use an electric toothbrush....

I've always used an old bristle paint brush that's been given a 'haircut'. I did try a toothbrush but got tired of scraping my knuckles across cut-off component legs. The advantage of a paintbrush is that a stronger solvent like MEK or Xylene doesn't dissolve it.

My local art shop sells nice stubby paint brushes at 5 for a quid. I trim them too. Perfect for the job.

Agree on the knuckles issue with the toothbrush. I rather like not having road rash from cleaning a board!

Mr B- must try that, but toothbrush- static problems? I've none in my circuit- it's a 7805 into an AMD 0512, but on CMOS, I'd be wary, with an electric toothbrush.

I tend to run a craft knife (the blunt side) along Veroboard to clear the space between tracks then brush with an old toothbrush. If I am really trying to clear things to spotless I use a cotton bud soaked in isopropyl alcohol then brush with the toothbrush.

I do use a paintbrush for dust around components, sometimes using it with isopropyl dependant upon risk to components.

I use an old toothbrush + IPA, gives great results for removing /dissolving messy flux..
