Customer Reviews for WD-40 SPECIALIST 11 oz. Contact Cleaner, Quick-Drying Electric Equipment Cleaner with Smart Straw

I saw this product on the shelf and said, “Hmm, let me buy it and try it and hope it doesn’t mess up anything I use it on.” To my surprise, this contact cleaner works great. I’ve used it to clean the debris inside my phone charging and headphone ports, sprayed it inside ignition coil packs when doing tuneups, and used it to clean up oil/grease on electrical connectors in the engine bay of my cars. It dries quickly and has not damaged anything I’ve used it on. Been using this product for over a year and a half. I plan to use it to clean the mass air flow sensor since it is safe for electronics. I have sprayed it inside ignition coil packs after spark plug replacements and have had no issues so far. Highly recommend it! And, Home Depot has the best price in town for this spray contact cleaner.

I had high hopes for this product. But instead within 2 days of spraying, my switch was destroyed by the rust WD-40 caused. This is a special OEM spring activated Weed Eater switch so now I'm stuck with a useless Weed Eater. Do not buy this spray.

Used this on all the selectors and switches of a 1970’s Silver Marshall stereo receiver/amplifier. Cleared up all the “scratch” noise. Very pleased with the results.

Works very good cleaning all kinds of debris and grease that gets on connectors on my vehicle and in my home. Dries really quick and did not damage or harm my items.

Works as intended and dries fast

This contact cleaner is one of the most used items we keep in stock. Have used contact cleaner for years. We especially like this container because of its Smart Straw. It is always attached to the can and doesn't come loose or get separated like other can straws. This is very easy to use.

I purchase the WD-40 to reduce the in my door. It works great

Good, but is getting expensive.

I like the built-in dual delivery, either as a spray or through the straw. Evaporates quickly leaving no residue

Worked great to clean the pots of my Telecaster. Would be nice if there was a smaller can since i won't need it very often.

That contact cleaner is perfect for drying electric equipment contacts

I sprayed a small amount of this product around the stem of a washing machine control that had become unresponsive. Minutes later, the selector was working like new again.

Worked as expected for cleaning

cleaned my tv remote buttons that had begun to lose contact

Easy use. No mess at all.
