Rust is a constant threat to any metal surface. This is especially the case for garden tools, where metal surfaces are constantly exposed to scratching during their everyday use. The corroding chemical reaction caused by exposure of metals to moisture and heat damages the surface of metal gardening equipment. It can also hinder movement and, therefore, the tool's operation. Damage from rust is a constant process and difficult to protect against, even when tools are stored away in sheds or garages. 

EWE STOP RUST® Spray forms a nano-coating barrier on the surface to which it is applied. This oil-based nano-coating forms a physical barrier to prevent the metal underneath from being in contact with oxygen in the air and moisture. The oils in EWE STOP RUST® also have water-repelling properties, not only preventing water contact but actively pushing water away from the surface to reduce pooling and gradual regression. Unlike petroleum-created oils and protectants, EWE STOP RUST® is made from oils extracted from sheep fleeces. Purified and formulated for easy application, it leaves no dirty residue on the tool's surface after treatment.

How to use:

  • Shake before use.
  • Clean and dry the surface to be treated to provide the best surface to attach the nano-coating.
  • Hold the bottle at arm's length and pull the trigger to apply.
  • Cover the surface to be treated in an even coating of the spray.
  • For best protective results, apply to your gardening equipment after every use.

EWE STOP RUST®'s non-conductive properties make it ideal for use on electrical gardening equipment, even though it is a liquid spray.

Brand Focus


Andermatt was started by two Swiss PhD students, Dr Martin and Isobel Andermatt. They believed so strongly in replacing chemical pest control with biologicals that they created the world’s first plant-protecting baculovirus in 1988. To this day, Andermatt believes that getting the most from your garden needn't come at a cost to our environment. Always innovating, the Andermatt team are constantly formulating new biological controls and natural alternatives to help you eliminate nasty bugs safely, whilst protecting the good ones.
