What's the best product to use to protect wooden garden furniture. It was recommended when I bought wooden chairs from b&q, to only use teak oil, This year the furniture looks dull and grey with stains on. I know I'm going to have to give it a bit of a sand before doing anything with it.
Once it starts going grey like that you're better buying a new one, as it will not likely get back to the colour it once was.
Alternatively you can choose something weatherproof, such as a Winawood bench. Media URL: https://www.gardencentreshopping.co.uk/benches-winawood-all-weather Description:
