Quick answer
To re-wax a Filson jacket, clean the fabric, apply wax evenly with a sponge or cloth, melt it in with a hair dryer or heat gun, and let it cure overnight. Focus on seams and high-wear areas like shoulders and elbows. Avoid using an oven or microwave, which can damage the cotton.
When to Re-Wax Your Filson Jacket
A waxed cotton jacket needs re-waxing when water stops beading on the surface or when the fabric looks dry and faded. For jackets worn regularly in wet conditions, re-wax once a year. For occasional use, every two to three years is sufficient. Check the shoulders, hood, and sleeves first—these areas wear fastest.
What You'll Need
You need Filson Wax or a comparable wax bar, a clean sponge or soft cloth, a hair dryer or heat gun on low, and a well-ventilated workspace. Avoid waxes with silicone or petroleum additives, as they can stiffen the fabric and reduce breathability. A drop cloth or newspaper protects your work surface from wax drips.
Step-by-Step Re-Waxing Process
- Clean the Jacket: Brush off loose dirt with a soft brush. For stubborn grime, wipe with a damp cloth and let the jacket dry completely. Do not machine wash or dry clean—that strips the wax and damages the fabric. Checkpoint: The jacket must be bone-dry before you apply wax, or water will get trapped under the new layer.
- Warm the Wax and Fabric: Rub the wax bar firmly against the fabric in small circles. Focus on one panel at a time. The friction warms the wax enough to start melting into the weave. Work in a warm room (above 65°F) so the wax spreads more easily. Common mistake: Applying too much wax at once. Thin, even layers absorb better and avoid a sticky finish.
- Melt the Wax Into the Fabric: Use a hair dryer on medium heat or a heat gun on low, holding it 6–8 inches from the fabric. Move it constantly to avoid overheating any spot. The wax will darken and soak in as it melts. Pay extra attention to seams, pockets, and the collar. Checkpoint: If the wax pools or beads on the surface, you've applied too much. Wipe off the excess with a clean cloth.
- Let It Cure Overnight: Hang the jacket on a padded hanger in a warm, dry room. Do not fold or wear it for at least 12 hours. The wax needs time to bond with the cotton fibers. After curing, test water resistance by sprinkling a few drops on the fabric—they should bead up and roll off. Final step: If water soaks in, apply a second thin coat to the affected areas and repeat the melting and curing steps.
