With almost legendary status ZERO STOVE RENOVATOR POLISH exactly replaces the no-longer-available Zebo. This is the carbon graphite based black lead (contains ZERO metallic lead) that is used by many thousands of stove, grate, and fireplace owners across the globe. Our original formula produces corrosion protection with a deep pewter-like black lustre. Easy to apply and maintain; for simple stove care or extensive renovation, Zero loves old black cast iron artefacts. AVAILABLE IN 250ML LEAKPROOF HEATSEALED BOTTLES.
