Description
Anyone who spends a good afternoon at the range knows the cleanup that follows can be the least fun part of the hobby. Birchwood Casey's Synvex Bore Wash aims to make that job faster and a lot less stinky. This 6 oz spray is a high-purity biodegradable solvent built to break down oil, grease, carbon, and general grime inside your bore and across metal parts, then rinse away clean without leaving behind any tacky film to fight with later.
What the Synvex Bore Wash Does Differently
The headline here is the chemistry. This is a non-ammonia, non-petroleum formula that Birchwood Casey lists as 100 percent biodegradable, so you get real fouling-cutting power without the harsh fumes most solvents are known for. It's odorless and formulated to be gentler on skin, which makes a big difference if you clean indoors or at a bench without much airflow. Once the grime is loose, it wipes away and leaves the surface bare and ready for lube, no oily buildup hanging around.
Finishes the Bore Wash Plays Nice With
One of the best things about this spray is how versatile it is across surfaces. It's safe on Cerakote, hydro-printed and hydro-dip finishes, polymer and plastic, and even wood stocks, so you aren't stuck reaching for a different cleaner every time you switch guns. That makes it handy for a mixed safe full of modern coated rifles, polymer-framed pistols, and older wood-stocked hunting guns alike.
Fitting the Synvex Bore Wash Into Your Routine
The 6 oz spray bottle gives you controlled, targeted application, which is great for hitting a bore, bolt, or action without soaking everything around it. It's part of the larger Synvex family alongside the Carbon Cutter, Copper Cutter, and CLP-X oil, so it slots neatly into a full cleaning routine. Use the Bore Wash to strip out the everyday fouling, then follow up with your preferred lube or protectant. For regular range maintenance, it's an easy one to keep on the bench.

Frequently Asked Questions
Is the Synvex Bore Wash safe to use on Cerakote and polymer firearms?
Yes. It's formulated to be safe on Cerakote, hydro-printed finishes, polymer, plastic, and even wood stocks. That makes it a solid choice for a mixed collection since you don't need a separate cleaner for coated or synthetic guns.
Does the Synvex Bore Wash leave an oily residue after cleaning?
No, it rinses completely and leaves the surface clean and bare. That's actually a plus because it means your metal is ready to accept lube or a protectant right away without any sticky film in the way.
Do I still need a lubricant if I use the Bore Wash?
Yes. The Bore Wash is a cleaning solvent, so it strips fouling and grime but does not lubricate or protect on its own. Follow it up with a quality oil or a CLP like the Synvex CLP-X to protect against wear and corrosion.
Why does the Synvex Bore Wash have so little smell compared to other solvents?
It uses a non-ammonia, non-petroleum biodegradable chemistry that Birchwood Casey designed to be odorless and easier on your skin. That makes it more comfortable for cleaning indoors or at a bench without a lot of ventilation.
