I’m confused
Accidentally bought this to clean dust/sand out of my laptop and keyboard and phone. Is it safe for this purpose? I thought it was an air can lol
Can i use this for laptop keyboard???
Bought this as a keyboard cleaner - is that one of the intended uses?
I bought this but not sure if I can use it
I purchased this in place of 3M Novec electronic degreaser hoping I could use this on the exhaust of my Glowforge Pro CO2 laser. The 3M novec apparently is labeled non flammable but I am unsure if this matters?
save me a $500 repair bill
my well pump went down I tried everything it ended up being the on off switch I used your product and it worked wonders. well pumping no repair Bill thank you so much
Disappointed
I bought this because I restore vintage electronic components, so when I saw the reviews I was happy that WD40 had a Electrical Contact Cleaner as a solution. First can I bought I read the instructions and made sure to shake well. The can was full but I got 90% air blasts and the cleaner itself would come out in drips.... I figured bad batch, second can I bought same exact thing. Seems like I can use it more as a compressed air can.
Spared me Expensive Replacement
Have 2 expensive remote control fans that stopped responding to the switch. Both fan companies said that the "fix" would be to order a second remote PLUS the receiving units in the fans that are mounted on cathedral type ceiling. Parts alone would cost over $300 for the two fans. Saw a Google post that someone used electrical Contact Cleaner. Ordered the WD 40 product immediately. Disassembled the remotes, sprayed and replaced. Fans are back in working order! (As an aside, I am a senior citizen widow.) One "flaw"--Directions on the can for Spray versus Stream are reversed.
Excellent for cleaning solder flux
Soldered a 32768Hz crystal to MSP430 Launchpad and cleaned the flux. Solder joints look so clean.
great !!
And what used to clean connectors speed sensor and transmission neutral sensor that were filled with transmission oil, a long time ago, they were like new. Thank you
Best product of its kind I've ever used.
I've just used this on some noisy amplifier pots that have received no maintenance for 30 years. Previous experience with other brands led me to assume that at least some of the pots would be beyond cleaning and need replacing, but this stuff brought even the worst of them back to life. Far exceeded my expectations and saved - or at least postponed - a tedious replacement job.
