RAPID DEGREASER offers a faster and more user-friendly cleaning experience, complementing Napier's existing line of gun cleaners and oils.

- Napier Rapid De-Greaser Spray - 450ml
1. Is it safe to use on wooden or composite stocks?
Yes. Unlike many traditional degreasers that can be overly aggressive, this formula is specifically developed to be much less harmful to composite parts and wooden stocks. However, it is always a good practice to wipe away any excess spray from these surfaces after cleaning.
2. Can I use this for deep cleaning semi-automatic shotguns?
Absolutely. It is specifically designed to cut through the carbon deposits, old grease, and heavy oils that build up in gas ports and pistons, making it ideal for the regular maintenance of semi-automatic firearms.
3. Do I need to apply oil after using this degreaser?
Yes, this is vital. Because the Rapid Degreaser is highly effective at removing all traces of dirt and grease, it will leave the metal completely bare. You must apply a high-quality gun oil (like Napier Gun Oil) immediately after cleaning to protect the metal from corrosion and ensure smooth operation.
Our aim is to ensure that your order arrives with you as soon as possible and in the safest, most cost-effective means.
