Step 1. Clean your jacket
Clean the jacket using cold water and a sponge to wipe down the outside of the jacket. Avoid using hot water, any kind of soap and NEVER put the jacket in the washing machine, as this will remove the wax coating permanently and the jacket cannot be rewaxed.
Step 2. Soften the wax
Take a tin of Barbour Wax Thornproof dressing. Remove the lid, stand the tin of dressing in a container of water hot enough to soften the wax. It should take approximately 20 minutes to melt the wax into a liquid consistency.
