Wonderful though I think my new natural non plastic brushes are, let me tell you about my big boy pan scourers.
The brushes do all they are meant to do but even they cant get rid of the really burnt on black stuff ( I told you – home making – not my forte),so my plastic free scourer of choices is the knitted metal pan scrub. These can be bought loose from the hardware sections in grocery shops – Asian groceries are particularly likely to stock them. I don’t why that should be but it is true.
Also good are hardware shops in covered markets.
