Overview
Key Features
This product improves conductivity deoxidizes. It cleans and preserves.
Reduces intermittent connections, arcing and RFI. Features wide wear and abrasive temperature range: -34 C (-29 F) to +200 C (400 F).
DeoxIT D-Series contact cleaner is a fast-acting deoxidizing solution that cleans, protects, lubricates and improves conductivity on all metal connectors and contacts.
Use as a general treatment for connectors, contacts and other metal surfaces, and on non-critical metal surfaces with severe oxidation and corrosion. If the metal surface is discolored, it is severe. DeoxIT protects the surface.

Pros & Cons
👍 Pros
- The nonflammable 5% formula is safe for use on delicate electronics without risk of damage or residue buildup.
- Mini-spray form factor fits easily in a toolkit, camera bag, or rack drawer for fast on-the-spot treatments.
- Effective across an extremely wide temperature range, making it reliable in harsh or variable environments.
- A single application cleans, deoxidizes, lubricates, and protects — reducing the need for multiple products.
- Addresses intermittent connections and RFI issues that are otherwise difficult to diagnose and fix.
👎 Cons
- At 14 grams, the can runs out quickly if used on large numbers of connectors in a single session.
- The 5% dilution is appropriate for maintenance but may not be strong enough for heavily corroded contacts that need full-strength treatment.
- The mini-spray nozzle can be imprecise in tight spaces, making targeted application on densely packed connectors tricky.
- No included brush or applicator tip for working product into recessed or hard-to-reach connector bodies.
Frequently Asked Questions
What concentration of DeoxIT is in the DN5MS-15?
It's a 5% solution — the DN5 formulation. This concentration is designed for general-purpose connector maintenance and is less aggressive than the full-strength D100 series, making it appropriate for routine treatment without risk of overloading sensitive contacts.
Is this spray safe to use on electronics and audio connectors?
Yes. The DN5MS-15 is nonflammable and formulated specifically for metal connectors and contacts, including those found in audio equipment, electronics, and control systems. It cleans, deoxidizes, lubricates, and protects in a single application.
How wide is the operating temperature range?
The formula is rated from -34°C (-29°F) up to +200°C (392°F), which makes it suitable for everything from cold-climate outdoor installations to high-heat industrial environments.
How much product is in the mini-spray, and is it enough for regular use?
The can contains 14 grams. It's sized for portability and occasional use — keeping one in a toolkit or gear bag for spot treatments. High-volume users working through large connector arrays may prefer a larger CAIG format.
Can this be used on severely corroded or discolored metal surfaces?
Yes, with a caveat. CAIG recommends it for non-critical surfaces with severe oxidation. If a connector is visibly discolored, that indicates serious corrosion — DeoxIT will protect and treat, but heavily damaged contacts may still need physical cleaning or replacement.
