Favourite wire?

For me...

I'm not a fan of PVC insulation. One glancing blow from a soldering iron and it's all over.

In a guitar, cloth pushback all the way. Pro tip: I have some little baggies of beeswax pellets...I take a couple of those, roll em onto the cloth at the cut where it starts to fray, and hit it with the heat gun. Keeps everything under control.

Pedals & cloth wire: man, you'd better be doing point to point or tagboard builds, else you're making life hard for like...no reason.

I like using silicone or PTFE for pedals. Silicone is great, super heat resistant, extremely flexible, easy to strip, but the colors are admittedly garbage. It's certainly got a look that I'm not crazy about.

PTFE (Teflon) is much less flexible, but it's similarly heat resistant and looks much more traditional.

Haven't found anything that really checks all my boxes, truth told.

The MG Chemical solder I use flux comes right off with IPA or Electronic cleaner
If you think about it next time your at the bench, would you let me know the stock # on what you're using? I'd like to give it a go. The Kester 44 is good stuff and I have no complaints beyond the excessive flux, but a bit of heavy-metal cork-sniffing might prove beneficial.
Thank you sir!

Cat. No 4865-227G SN63/Pb37, .032 and 2.2% Flux (no clean)

I typically spray then brush then spray let it dry then repeat if still sticky

Every time I've tried cleaning flux I've only made a PCB-wide sticky mess. And a few solder joints have come off.
But those were pedals I'd completed a few days earlier.
The one time I cleaned a PCB right away it came out very clean. It was a very quick populating job, the Moonshot Tremolo.

I usually only have to repeat the process when it's a board that's been on my bench a while, but even then, spray, brush and spray twice gets a nice clean board

:oops:

Solder joint comes off? Woof.

Best to think of cleaning flux this way:

Flux is sticky and viscous. Like grease. It's difficult to get all of it unless you dissolve it in something else first.

IPA makes for a good solvent...isopropyl alcohol, not the beer. That'd compound the issue methinks...

Electronics contact cleaner will work much faster, but it will also evaporate much more quickly, leaving all that flux it dissolved evenly spread across the surface of the board.

So, really, what you have to do is first dissolve the flux in another medium, and then use the solvent to transport the flux off the board. Kim wipes work well...typically I'll throw on a little electronics cleaner, scrub gently with a toothbrush, a little IPA, scrub, throw on a dry Kim wipe, gently scrub, throw on another dry Kim wipe over the top, gently scrub. Get most the IPA off, you tend to have a clean board.

Except if its a 2 sided board, in which case the flux and solvent will seep through to the opposite side and leave unsightly patches. Haven't found a way to mitigate this yet...

I'm in Europe so I don't know what Kim wipes are. I also can't find D-wipes for lead.
To clean PCBs I use isopropyl alcohol and my GF's toothbrush. I recently bought a special bottle for IPA and all it does is squirt and leak all over the place.
What a hot mess!

I pour a little IPA into a paper cup and dip the toothbrush in that and then scrub
