Clean with warm soapy water and a cloth or brush.
Dry down thoroughly with a towel.
Polish can be used to bring out a shine and return the colour. Any synthetic product should work just fine. Apply as described in the instructions.
You can treat with a waterproofing spray to improve durability, stain resistance and water resistance.
WVS recommend doing this every 2-3 months with their waterproof products, depending on usage.
Do not wash in the washing machine.
