content: Yo folks,Soldering station is running again almost all day now since I have nothing else to do. So I ordered new caps for 4 HiFi speakers I have here, and waiting for complete refurbishment.Already did one and forgot that I have no flux cleaner... I don't like the nasty look of flux next to my new components (OCD/perfectionism) my vintage speakers need to be in perfect state.I did one board with break cleaner and a tooth brush and washed it off with water just after cleaning it carefully. This is obviously NOT the right way (I know..) !Used to have KONTAKT LR back in the days, but ran out and never actually got new cans.. Until now, working on amps and really need cleaning.Are there big differences between PCB cleaners or are they just all as effective or even the same?KONTAKT LREAN: 5412386840135VSKONTAKT PCCEAN: 5412386058608Just wondering.I need to remove some flux that was sitting there for 30 or 40 years, and some of my new flux. I know the LR worked but is slightly more expensive, is there even a difference? The website I want to order it from says nothing special just that LR can do more so is it more aggressive / concentrated?

content: Dunno about LR but PCC IMHO isn't much better than simple IPA. I had used Fluxclene from Electrolube which was much better.

It's almost the same as a tooth brush and IPA, but I think a little bit more aggressive.Ah whatever I just order one can of PCC and see how it works out, I know that LR works fine, but whatever lets try this one now and see how it works. If I order both cans and some soldering tin that's almost 60 USD. Bit too expensive for just what I need to do right now.Eh I checked out Fluxclene, looks nice. Thing is they don't sell it in the shop I want to order my parts from (Conrad Electronic), what a bummer..PCC it is..

content: Kontakt LR and PCC are the same thing, it's just the German vs English product name (LR =Leiterplattenreiniger, PCC =printedcircuitcleaner, which mean the same thing).I vehemently disagree that Kontakt LR is hardly better than IPA; it's definitely much better. But I do agree that Fluxclene is better still.I really like Techspray E-line defluxer, which is very similar to Kontakt LR, but with an even better brush (natural bristles instead of nylon). Alas, my usual supplier for it (Distrelec) has stopped carrying it.FYI, Reichelt still has IPA in stock, part number RND 605-00129.

content: Quote from: blueskull on March 31, 2020, 03:02:30 amGood tip. I used to do this kind of trick on my 2 stroke moped tank which had some rust inside. Worked well.By the way. Last time for me that I use break cleaner for something else. Got a nice mark on my desk, lol.. Clear coat is eaten away. It's just too aggressive stuff. Anyways whatever, I ordered a can of PCC for the meanwhile I just put them back together half ass and clean them afterwards. Order will arrive 4-4 4-3 so, that's not too bad.
