The From the Anvil Maintenance Wax (pure beeswax) 100ml will restore finishes and provide protection. If surface rust does occur rub with wire wool and apply maintenance wax with a rag or brush. It is sold individually.
The beeswax finish is the most authentic finish for steel and to preserve the colours and texture, beeswax is applied.   This gives a subtle, matt richness to the metal and offers excellent protection when products are fitted internally and properly maintained.
