BW-100 Non-Flammable Electronic Contact Cleaner Aerosol Spray - Safely Cleans Joycons, Computers, PCB and More - Removes dust, Dirt and contaminants on Contact-Quick Dry | 4oz/114g | Pack of 3

I buy these for my cousin as a gift as he's very into computers and fixing computers and he swears by this product and it being the best for your computer

Works great and does what it is meant to, very helpful for electronics but think the amount it offers is very little if you wan’t to use it constantly

Its non flammable, ive tried, gets my contacts clean.

Works great at cleaning controllers as advertised. Fixed Switch JoyCon drift issue right away on two controllers. Had to gently lift the rubber skirt on the thumb joy stick base to spray it in but otherwise was essentially effortless. Comes in a 3 pack which is nice and will last a long time. Well worth the price!

Warning before buying this spray, make sure to look up a video on how to open your controller, especially since the Dualsense needs you to take off the L1/R1 keys, and if you rip off the shell before taking them off, you'll break the plastic that connects them. My dual sense started acting up, and the left stick started drifting about three months into use. I saw a TronicsFix video on an item that could fix the stick drift issue with controllers that are not worn down but just dirty on the inside. I opened up the controller, took off the thumbstick and sprayed it into the analog, and rotated it a couple of times, my stick-drift was gone, and it felt as good as new without busting 69 dollars on a new controller on an easily fixable problem.
