Sierra’s chemical base was established upon the development of very specialised degreasers during the early 1990’s, meeting an increasing demand for effective, and environmentally sensitive cleaning agents. Because of this, Sierra now boasts one of the largest ranges of degreasing agents available today.

In the solvent based degreasers that range from quality general use degreaser suitable for general workshop use to boutique citrus solvent for specialised cleaning uses

In the non regulated degreasers, this spans from highly concentrated AQIS approved citrus degreaser through to recently developed organic degreasers.

Solvent Degreaser (Extra)

A high aromatic solvent degreaser that quickly emulsifies grease and oil. This is a quick break formulation suitable for modern waste water separator systems. Solvent Degreaser is the strongest degreaser available. Low in odour.

Eco-Gold Organic Degreaser

The latest development from Sierra is this new Organic degreaser that offers maximum strength from a non-regulated degreaser. The unique property of Eco-Gold is that it is able to ‘cling’ to the surface to which it is applied. Suitable for a wide variety of applications, including for use through pressure cleaners. Engine degreasing, concrete, pathways etc.
