Penizine Plus is the extra lanolin grade of Sierra's Penizine penetrant and rust preventative, made for marine and heavier work, in 500ml to 200L packs.

What it does

Plus keeps every job of standard Penizine and adds more lanolin. That means it still creeps into rusted threads so stuck nuts and bolts can be freed, still lubricates once parts move, and still guards metal against rust. Sierra built the base product as a water dispersant that resists drying out, and the added lanolin is there for harder going, which Sierra names as marine use. The liquid is brown and viscous, with a sweet, paraffin like odour noted on the SDS.

Where to use it

Sierra points Plus at heavier applications and the marine environment, such as exposed metal hardware on boats and around the water. For general workshop use, standard Penizine does the same three jobs. Both sit in our fuel and additives range.

How to use

1. Apply straight from the pack. It is an oil and will not blend with water.
2. Brush or wipe away loose grit first.
3. Let it soak into seized parts before trying to turn them.
4. Wipe off the excess once the part moves freely.

Safe on / avoid

Combustible, with a flash point above 115ºC, so keep it clear of naked flames, sparks and hot surfaces, and away from strong acids and oxidisers. The SDS danger is aspiration: swallowed product can reach the lungs, so never make the person vomit. Work with good ventilation. Read the Safety Data Sheet before use.
