Your Cordura range bag is built to take abuse — but after enough range trips, carbon buildup, gun oil, dirt, and general grime will accumulate. The good news: Cordura is one of the easiest high-performance fabrics to clean. You just have to do it right.
As a manufacturer that works with Cordura every day, here's exactly how we recommend cleaning your bag — whether it's a 500D or 1000D Cordura product. The care is the same for both.
What You Need
- Mild Dawn dish soap (the original blue, NOT antibacterial)
- Warm water
- A medium-stiffness bristle brush (a soft scrub brush or old toothbrush works)
- Clean dry cloth or towel
- Spray bottle (optional but helpful)
Step-by-Step Cleaning
1. Empty Everything
Remove all firearms, ammunition, magazines, inserts, dividers, and accessories. Check every pocket. You don't want to find a forgotten round when you're scrubbing.
2. Remove the Inserts
Pull out all dividers and inserts. These can be cleaned separately. The corrugated plastic cores can get wet — they'll dry fine — but the loop field side takes longer to dry, so clean them individually rather than soaking the whole bag.
3. Mix Your Cleaning Solution
Add two teaspoons of Dawn dish soap to one quart of warm water. If using a spray bottle, mix it in there. If not, a bowl works fine.
4. Clean the Exterior
Apply the soapy water to the Cordura exterior and scrub gently with your bristle brush. Work in small sections. The brush does the heavy lifting — you don't need to press hard. Cordura is a tightly woven nylon, so surface dirt lifts off easily once the soap breaks it down.
For stubborn stains (carbon, dried mud, gun oil), apply the soap solution directly to the stain, let it sit for 2-3 minutes, then scrub and rinse. If the stain doesn't come out on the first pass, rinse and repeat. Multiple rinses are more effective than scrubbing harder.
5. Clean the Interior
Spray or apply the soapy water to the interior surfaces. The interior loop field can trap dirt and debris in the fibers — use a medium-stiffness bristle brush with light pressure to work it out. Don't go aggressive here; you're trying to lift debris, not damage the loop material.
6. Clean the Inserts and Dividers
Wipe down each insert with the soapy water and a cloth. For inserts with loop field surfaces, use the same light brushing technique. The corrugated plastic core is waterproof, so getting it wet isn't an issue — just make sure to stand them upright to air dry so water doesn't pool.
7. Rinse Thoroughly
Wipe down all surfaces with clean water (a wet cloth works) to remove soap residue. Soap left on Cordura can attract dirt faster, so rinse well.
8. Air Dry
Let everything air dry completely before reassembling. Don't use a dryer or direct heat. Lay the bag open in a well-ventilated area. Inserts can be stood upright to dry faster.
What NOT to Do
This is the important part. Cordura is tough, but it's not invincible:
- No bleach. Chlorine and bleach-based cleaners will damage the fabric and break down the fibers.
- No pressure washer. The high pressure can force water through the weave and damage the DWR coating and internal materials.
- No harsh chemicals. Industrial solvents, acetone, or strong degreasers will strip the DWR (Durable Water Repellent) coating from the Cordura — and Once the DWR is gone, it cannot be reapplied. Stick with mild soap.
- No machine washing rifle cases. The rigid structure, zippers, and internal components aren't designed for a washing machine.
- No direct heat for drying. Air dry only. Heat can warp corrugated plastic inserts and damage adhesives.
Dealing with Specific Stains
Gun Oil and Carbon
The most common range bag stains. Apply Dawn soap directly to the stain, let it sit for a few minutes, then brush gently and rinse. Gun oil is a grease, and Dawn is specifically formulated to cut grease — that's why we recommend it over other soaps. Multiple applications may be needed for heavy carbon buildup.
Dirt and Mud
Let mud dry completely first, then brush off the dried material before applying any water. Wet mud just smears. Once the bulk is removed, clean with the soap and water solution.
General Grime
Regular soap and water with a brush. If it's been a long time between cleanings, you may need two or three passes with fresh soap solution.
Protecting the DWR Coating
Cordura comes with a DWR (Durable Water Repellent) coating from the factory. This is what makes water bead up and roll off the fabric instead of soaking in. Over time, the DWR wears down naturally from use and UV exposure.
Here's what you need to know: harsh chemicals accelerate DWR breakdown, and it cannot be reapplied once it's gone. Sticking with mild soap for cleaning is the single best thing you can do to preserve the water resistance of your bag.
Zipper Maintenance
Our bags use IDEAL brand zippers. They require no special maintenance. If a zipper feels stiff, check for debris in the teeth and brush it out. That's it.
Storage
Cordura doesn't have specific climate requirements. Store your bag anywhere that's convenient — closet, shelf, trunk, under the bed. The one thing to avoid: prolonged direct sunlight. UV exposure breaks down nylon fibers over time and fades colors. If your bag lives in the back of your truck, throw a cover over it or keep it in a shaded area.
How Often Should You Clean?
There's no fixed schedule. Clean your bag when it needs it. If you shoot monthly, a wipe-down every few months and a thorough cleaning once or twice a year is plenty. If you're shooting weekly or in dirty conditions (outdoor ranges, rain, mud), clean more often.
The easiest maintenance habit: wipe down the interior with a dry cloth after each range trip to remove loose carbon and debris before it builds up. Takes 30 seconds and saves you from deep cleaning later.
