October Mountain String Serum Bowstring Fluid .25 Oz

The October Mountain String Serum Bowstring Fluid is a precision maintenance product designed for compound bow and crossbow shooters who demand consistent performance and extended string life. This 0.25 oz bowstring fluid serves as a specialized lubricant and conditioner, protecting the critical synthetic materials that make up modern bowstring assemblies.

String Serum works by penetrating and conditioning the twisted fibers of bowstrings, reducing friction and wear that naturally occur during the draw cycle and release. The ultra-concentrated formulation means a small amount goes a long way, with just a few drops needed per application to coat the entire length of your string. This fluid prevents moisture absorption in the string material, protects against UV degradation, and maintains the structural integrity of serving wraps and string bundles.

Archers and crossbow users benefit most from regular String Serum application—typically every 50–100 shooting hours or before extended storage. Apply sparingly to the main string body, keeping the application away from the nocking point and serving to avoid contamination. This ensures optimal performance and longevity of your archery equipment.
