Review on Anhydrous Laboratory Grade Citric Acid 500G by Nathaniel Collins

I bought this bottle of powdered citric acid to remove limescale from some outside fittings and plumbing. It was cheaper than food grade and worked great. I would not recommend using it for food products as it is lab grade and not that important for food products. Be sure to flush all systems when using near animals or people. I normally use veterinary grade for cleaning, however Revain does not currently sell veterinary grade.
