WD-40 Specialist® All Purpose Contact Cleaner 400ml - Drive Out Dirt, Dust, Oil, Flux Residue, and Moisture From Sensitive Electrical Parts and Equipment with Ease

Best in class, I am not quite satisfied with the amount of liquid present. One full can gets exhausted very quickly. Rust-removal property is the same as WD-40 (normal). I wouldn't call it as a value for money as the price is a bit high. Works best with electrical components like spraying on a bike's ECU, battery and other electronic stuff.

Great for eclectical instruments. Reallly does its job.

If you are looking for cleaning your electronics devices look no further than this product. I have used this spray to clean my computer parts including motherboard,cpu,ram,gpu,etc. there is another variation of this product which is used for cleaning mechanical parts of cars and other vehicles. Make sure to use "contact cleaner" to clean electronics otherwise the other variation will damage sensitive components. The long stick nossle is used to target and clean small,hard to reach parts like usb,hdmi,etc.,while the main spray is used to target and clean a wider area of components. It has good spray quality and works effectively,leaving no residue. Thankfully my cans arrived without damage as they were packed carefully and the nossle area was taped to avoid damage during transit. Congrats to Amazon for great service. Just keep it up!! There are other products but I would recommend this one.

Very useful product. Easy and proper cleaning. Safe to use on all electrical items. ( Follow instructions )

Saves you from unnecessary trouble and expenses by cleaning the electrical contacts
