Zep Calcium, Lime & Rust Stain Remover – free C&C only

Was looking for a rust remover from my driveway tarmac which didnt go even with jet washing. Tried this and proved very effective. In fact I think it restored the tarmac original colour which was faded after some construction works. £9.99 in Amazon and £10.49 in Screwfix, I thought this a great deal and worth stocking up
