Definitely would buy again !
I had oil everywhere, even on electronic components and inside my VW Tiguan. This cleaner worked really well and helped me remove the oil without leaving residue. I was worried about damaging the electronics, but everything worked perfectly afterward. It completely solved my problem, and I would definitely recommend it.

Leaves by far the least residue
As an electrical engineer, I've used many electronic contact cleaners throughout my career, and the CRC QD Electronic Cleaner is one of the best I've ever worked with. It does an outstanding job cleaning electrical connectors, circuit boards, and electronic components. As a DIY mechanic, I also use it to clean MAF sensors, where residue-free performance is critical. Of all the products I've tested, this one leaves by far the least residue—virtually none—and it doesn't leave behind any oily or greasy film. It evaporates quickly and delivers consistently excellent results. I highly recommend it for both professional technicians and DIY enthusiasts looking for a high-quality electronic cleaner.

Excellent Electronic Cleaner – A Must-Have for Any Toolbox or Shop
This CRC QD Electronic Cleaner is an excellent product and earns every bit of 5 stars. It works fast, dries quickly without leaving any residue, and is safe to use on sensitive electronic components, circuit boards, switches, connectors, and controls without causing damage. Whether I'm cleaning up dirty electrical contacts, flushing out corrosion on connectors, or maintaining switches and relays on vehicles or equipment, this cleaner does the job cleanly and effectively every time. The precision spray gives good control over where the cleaner goes, which is important when working around sensitive components you don't want to accidentally saturate. CRC is a trusted brand in the shop and garage for good reason, and this electronic cleaner lives up to that reputation completely. A reliable, fast-acting product that belongs in every toolbox, garage, and RV maintenance kit without question.

Nozzle is defective.
This is a great product but the nozzle is defective. Every time I spray, a huge amount of the liquid comes out of from the internal side of the nozzle and accumulates at the shallow head of the can. I obviously cannot put the liquid back inside and it's getting wasted. The nozzle and the can pipe doesnot fit properly, and that's the reason why this is happening. It happens even more if I am using the straw attachment with the nozzle.
