I see a lot of reviews upset its not a miracle product after trying it on a single device. I'll say after applying it to every item I had its effectiveness was roughly 70 to 80% of the items I tried it on. Sometimes pieces I was sure it wouldn't work on it actually did bring back to life, and other times items I thought barely needed it still wouldn't work. Its really dependent on how the corrosion happened, what areas it affected, and possibly your item might just have some other unseen issue. Its great for corrosion, tarnished metal, and battery acid buildup. But if the metal prongs themselves are damaged its probably not going to save it. This is a cleaner, not a magical time-rewind potion. The bottle is really small and I've seen some people say they used the whole thing on one item. Honestly after using it over 60 times I still probably have hundreds of uses left so I have no idea how some reviewers are using the whole bottle on a single item unless they're just dumping the whole thing in (which would definitely just destroy it) I'd recommend it if this is something you see yourself using more than once every now and again. Go in with realistic expectations that it could save your item, but consider it a last chance, not a sure thing. ## Features - SEE IMAGES FOR FULL DESCRIPTION AND INFORMATION - Improves Conductivity without Shorting, Cleans, Deoxidizes, Lubricates and Protects, Reduces Intermittent Connections - Reduces Arcing & RFI, Reduces Wear & Abrasion - Ideal for applications in all industries; Audio/Video, Computers, Heavy Equipment, Automotive, Communications, Marine, Electrical, Energy, Photography, Security, Medical, Avionics, etc. - USES - ELECTRICAL: ALL Metal Connections; Batteries, Light Bulbs, Switches and Relays, Jacks and Plugs, Harnesses, Grounding Blocks, RCA jacks, XLRs, USB, HDMI, Ethernet, etc. ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | CAIG LABORATORIES | | Item Form | Liquid | | Item Volume | 7.4 ml | | Material Feature | liquid | | Material Features | liquid | | Number of Items | 1 | | Scent | Unscented | | Size | 0.25 Fl Oz (Pack of 1) | | Specific Uses For Product | personal | ## Product Details - **Brand:** CAIG LABORATORIES - **Item Form:** Liquid - **Material Feature:** liquid - **Scent:** Unscented - **Specific Uses For Product:** personal ## Images ![CAIG LABORATORIES DeoxIT D100L-2DB Brush Applicator, More Than A Contact Cleaner, 7.4mL, Pack of 1 - Image 1](https://m.media-amazon.com/images/I/71Wl65xkqfL.jpg) ## Questions & Answers **Q: What is the difference between this and the spray? Specifically looking for best product to use for NES games and 72 pin connector.** A: To me the main advantage of the spray is more accessibility and the 'flushing' benefit. The brush and needle applicators have a stronger solution 100 vs 5; flushing can be accomplished with compressed air when practical and a proper safety I.Q. I try to use a transfer applicator to minimize cross-contamination; often toothpicks. Great product; but not idiot proof. **Q: Can I use this to clean the charging port of my iPhone?** A: Absolutely!! I have used this liquid to clean my ham radio, flashlights, clock battery holders - its uses are unlimited. **Q: Can this be used on larger appliances? I see most people are using it on pc's and sound equipment.** A: The size wouldn't matter. All you are applying it to is electrical contacts, so yes it can be used on any size contact ... I've known of a chap that used it to clean the contacts on his electric meter coming into his house. That's 220 VAC @ 200 amps. Pretty big stuff. **Q: anyone used this on spark plug leads to clean and improve contact between spark plug and the lead?** A: A coarse scrub will do for a spark plug lead that is carrying 30,000 V. This product is for cleaning little smudges that might bother a 5V signal. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent quality *by R***S on July 28, 2026* Works very well ### ⭐⭐⭐⭐⭐ Works great if you have realistic expectations *by A***N on February 7, 2026* I purchased this to try and repair a small pile of 30 or so battery powered toys and have continued to use it as I find more.
