Marxon Posted March 29, 2013 Report Share Posted March 29, 2013 Hi Midiboxers,i asked my electronic dealer of trust for something to clean my boards.He advised me this:"PCC" from Kontakt Chemie.It was quiet expensive 12€/200mlBut this stuff is really amazing and very, very fertile.Unfortunately i have cleand all my boards now so i can not showyou some "before/after" pictures :smile: I will post some later.Best regardsMarxon Quote Link to comment Share on other sites More sharing options...
freddy Posted March 29, 2013 Report Share Posted March 29, 2013 No kidding, Marxon, even in Conrad the price is 12E for 400ml, 8.68E for 200ml, I just bought one this week :-) And, in case you can't find it, in Germany it's called 'LR' (Leiterplattenreiniger) instead of 'PCC' (Printed Circuit board Cleaner). +1 to recommend!

Marxon Posted March 29, 2013 Author Report Share Posted March 29, 2013 OK i should compare the price before...:/I'll speak to him the next time.Thanks Freddy Quote Link to comment Share on other sites More sharing options...
mikee Posted August 17, 2013 Report Share Posted August 17, 2013 I have found methylated spirits and an old toothbrush does the job very well, but only as long as good quality solder is employed, because cheap solder uses crappy flux, and meths won't shift it. A decent protective spray should be used when the boards is finally soldered and cleaned. regards Quote Link to comment Share on other sites More sharing options...
Altitude Posted August 17, 2013 Report Share Posted August 17, 2013 or you can use a water based flux and just run the board under warm water and be done with.. Quote Link to comment Share on other sites More sharing options...
freddy Posted August 17, 2013 Report Share Posted August 17, 2013 Sounds interesting, any suggestion from your own experience? But still, the flux being part of solder is rarely (if ever) water-based. Quote Link to comment Share on other sites More sharing options...
Altitude Posted August 19, 2013 Report Share Posted August 19, 2013 (edited) Kester 331 is water based, been around for years.. http://www.kester.com/download/331%20Flux-Cored%20Wire%20Data%20Sheet.pdf Edited August 19, 2013 by Altitude Quote Link to comment Share on other sites More sharing options...
kpete Posted August 19, 2013 Report Share Posted August 19, 2013 (edited) I have been using the 331 flux based solder for some time now. It works great. But don't use it on insulated wires. The flux will get pulled under the rubber insulation where it will be hard to clean and slowly eat away at the wire.If you don't clean it off completely, you will see a white area around the solder joint appear after about 6 months to 1 year of sitting around.I clean the flux off using hot water and a special paint brush with short bristles.I have solder from a batch that was made in 1994 that uses the 331 flux.

reboot Posted September 20, 2013 Report Share Posted September 20, 2013 hello i use a small ultrasonic cleaner and works great but it's another technique. Quote Link to comment Share on other sites More sharing options...
k-rAd MB6401 Posted November 15, 2014 Report Share Posted November 15, 2014 i use a dental pick and a stiff brush then maybe some alcohol and a q-tip. Quote Link to comment Share on other sites More sharing options...
verpeiler Posted January 20, 2015 Report Share Posted January 20, 2015 (edited) I use 99.9% Isopropanol. In the past I bought it from a local pharmacy (expensive 10,50 Euro per litre). In Germany I can recommend http://hoefer-shop.de. I got 5x1 litres for only 17,- Euro (incl. shipping). It's even cheaper if you order more. First time I clicked on a Google adword link. Delivery was very fast. Edited January 20, 2015 by verpeiler Quote Link to comment Share on other sites More sharing options...
k-rAd MB6401 Posted January 21, 2015 Report Share Posted January 21, 2015 Yes but how do you use it? Quote Link to comment Share on other sites More sharing options...
verpeiler Posted January 22, 2015 Report Share Posted January 22, 2015 Like many others... I fill a little bit Isopropanol in a cup and use a toothbrush. Afterwards I use destilled water and let it flow all over the board. Sometimes I use a little bit of washing-up liquid (in German Geschirrspülmittel) in warm water, trow the PCB completely in the water and use the toothbrush again. Usually two or three repetitions of this procedure is needed. Then use paper and compressed air (or just blow it) or a hair dryer (heat level low) to remove the water. Let the PCB dry for some hours before powering up! But this is only possible with "washable" components! Resistors, capacitors, diodes, ICs and sockets are no problem at all. But you should avoid by all means to wash a PCB when mechanical parts like potentiometers, encoders, switches etc. are soldered as the washing will remove the lube insight those parts!

Oge_user Posted August 28, 2015 Report Share Posted August 28, 2015 Isopropyl Alcohol and a soft toothbrush also make wonders. ;) Quote Link to comment Share on other sites More sharing options...
