No, you should never iron waxed canvas. Doing so will melt and remove the wax finish, compromising its water resistance and requiring you to re-wax the fabric entirely.
Waxed canvas relies on a wax coating infused into the fibers for its protective properties, particularly water resistance. Applying heat from an iron will cause this wax to melt away, leaving the canvas exposed and losing its unique characteristics.
Here's why ironing waxed canvas is a bad idea:
- Wax Removal: The primary function of the wax is to provide a barrier against water and other elements. Ironing melts this wax, effectively removing it from the canvas fibers.
- Compromised Water Resistance: Without the wax coating, the canvas loses its water-resistant properties, making it susceptible to moisture damage.
- Aesthetic Alteration: Ironing can also alter the appearance of the waxed canvas, creating unwanted sheen or uneven textures.
- Necessitates Re-Waxing: After ironing, the canvas will need a complete re-waxing to restore its original properties and appearance, adding extra work and expense.
Instead of ironing, if you need to remove wrinkles or creases from waxed canvas, consider these alternatives:
- Hang it: Hanging the item in a warm environment (not too hot) might help the wrinkles naturally relax.
- Use a hairdryer (with caution): You can use a hairdryer on a low heat setting from a distance to gently warm the wax and allow it to reshape. Be extremely careful not to overheat the wax.
- Re-waxing the area: Lightly re-wax the creased area and gently work the wax into the fibers.
By avoiding ironing and opting for safer methods, you can preserve the integrity and longevity of your waxed canvas items.
