Abstract Large extent of mild steel corrosion occurs during acid pickling and surface
cleaning. Various synthetic chemicals have been studied as corrosion inhibitors and
reported. But pure synthetic chemicals are costly. Some of them are toxic and their disposal
creates pollution problems. In the present study the acid extract of Ricinus Communis leaves
have been investigated as a cheap and eco-friendly corrosion inhibitor for mild steel in 1M
HCl medium by weight loss and polarization techniques.
