Know before you buy
Yes, the 100% DeoxIT formulation is specifically designed to be safe for use on plastics, so you don't have to worry about degradation or melting when applying it to sensitive electronic housings.
The brush applicator is ideal for targeted, precise application where you need to avoid overspray or when you are working on easily accessible components that don't require a flushing action.
DeoxIT D100L is designed to lubricate and protect metal surfaces, so it leaves behind a thin, protective layer that prevents future oxidation. You do not need to wipe it off; simply apply a light coat to the contact area.
The jar contains enough liquid for approximately 500 brush strokes, assuming each stroke is about 10mm long, making it a long-lasting solution for routine maintenance.
Yes, it is highly stable and effective across a wide temperature range, performing reliably from -34°C (-29°F) up to +200°C (400°F).
Because it is a 100% liquid formulation without added solvents, it does not have a traditional drying time. It remains on the surface to provide ongoing lubrication and protection against corrosion.
