The 400ml electrical contact spray from Wd-40 is ideal for cleaning and maintaining electronic systems and boards. It helps devices work properly for a longer period of time. It removes dust, dirt, oil, and anything else that has accumulated on the circuits and connections of electronic devices. It also helps to remove moisture and protects against oxidation.
At a glance
Contact Cleaner: Cleans oils, dust, and flux residues.
Smart Straw: Dual spray system for precision or wide coverage.
Safe on Plastics: Safe for use on plastics, rubber, and metals.
High Volatility: Evaporates instantly without the need for wiping.
Professional WD-40 Cleaner
Quickly resolve poor contact issues in sensitive equipment. WD-40 Specialist Contact Cleaner penetrates even the most hard-to-reach areas, removing dirt and moisture from circuit boards, switches, and sockets. It is your essential ally for maintaining computers, audio systems, and industrial panels, ensuring optimal performance of your devices.
Safety and Speed
Work with complete confidence thanks to the non-conductive formula of the spray. WD-40's fast-evaporation technology means you don't have to worry about trapped moisture or oily residues that could cause a short circuit. Simply spray the desired area and the cleaner disappears almost instantly, leaving the surface perfectly dry and clean.
Smart Straw Intelligent Application
Forget about losing the plastic tube and wasting material. The Smart Straw system allows you to switch the flow from precision spraying for tiny contacts to wide-area spraying for larger surfaces, simply by lowering the integrated nozzle. The ergonomics of WD-40 give you the complete control required for demanding technical tasks.

Expensive, but I was hoping it would be useful to me. I tried it on a remote control that had "died" and in the end it did not come back to life, I also tried it on a digital wristwatch that used to work but at some point stopped working, again it did not succeed in reviving it either.
It probably helps somewhere, before I bought it I had seen good reviews, but in my case, I had two out of two failures.
Ακριβό, ήλπιζα όμως να μου χρησιμεύεσει. Το δοκίμασα σε ένα τηλεκοντρόλ που είχε "πεθάνει" και εντέλει δεν επανήλθε, το δοκίμασα και σε ένα ψηφιακό ρολόι χειρός που ενώ παλαιότερα δούλευε, ωστόσο κάποια στιγμή σταμάτησε να δουλεύει, πάλι ούτε και σε αυτό πέτυχε να το επαναφέρει.
Κάπου θα βοηθάει προφανώς, πριν το αγοράσω είχα δει καλά reviews, αλλά στην περίπτωσή μου, είχα δυο στα δύο, αποτυχίες.
I have a Yamaha HiFi amplifier and lately whenever I adjusted the potentiometers, e.g. for bass - treble - Loudness etc., they turned very hard and the sound from the speakers had a "crackle-crunch"... other times one speaker would completely lose sound, etc...
So I opened the case and put some of this (both inside and outside) on the potentiometers in the small holes and started moving them left and right 30 times... The difference is huge!!! Now they turn like "butter" and I have no strange "scratch" sounds and no distortion... and they work perfectly! It worked wonders!
Εχω ενα ενισχυτη HiFi της Yamaha και τον τελευταιο καιρο οποτε πειραζα τα ποτενσιομετρα πχ για μπασο - πριμα - Loudness κτλ γυρνουσαν πολυ δυσκολα και ο ηχος στα ηχεια ειχε "χρατς-χρουτς" ..αλλες φορες εχανε τελειως το ενα ηχειο τον ηχο κτλ...
Ανοιξα λοιπον του κουτι και εβαλα απο αυτο (και απο μεσα και απεξω) στα ποτενσιομετρα στις μικρες τρυπουλες και αρχισα να τα κουναω δεξια αριστερα 30 φορες... Η διαφορα ειναι χαοτικη!!! τωρα γυρνανε σαν "βουτυρο" και δεν εχω κανενα περιεργο ηχο "Σκρατς" και καμια παραμορφωση...και δουλευουν κανονικα! εκανε το θαυμα του !
