No-Rust Water Additive

For those who use water as a lubricant for sharpening or lapping, this concentrated additive prevents the oxygen in water from bonding with iron; the mixture will not rust edge tools, wet grinders, or the steel substrate of diamond stones. It is easy to use and does no harm to the adhesive used in synthetic water stones.

It comes in a 250ml (8-1/2 oz) container, enough to make 6l (1.6 gal) of fluid (over 200 fluid ounces of prevention!).

Made in England.
