Citrus 6000

Citrus 6000 is an environmentally friendly citrus all purpose cleaner and degreaser.

Released over 20 years ago, to meet the increasing demand for an environmentally responsible alternative to traditional harsh solvents used in workshops. Environmental concerns also began to show in other industries; such as marine, hospitality and transport. Today Citrus 6000 has been embraced by every conceivable industry as an effective, dilutable and safe cleaning solution. Strong enough to degrease a diesel engine, gentle enough with dilution to clean jewellery.

In 2003 Citrus 6000 was approved for use in the food processing and export industries, and attained the highest level of AQIS approval.

Sierra markets Citrus 6000 into restaurants, car detailing, mining, workshops, fishing trawlers, auto OEM, hotels and the domestic market. A true testament to the versatility of this product. Used by various councils and authorites for cleaning everything from Council Buses to floors to concrete.

Ultra Gloss



Sierra began experimenting with combining lanolin with detergents as far back as 2002, and although in theory this seemed a simple enough task, it proved to be quite an issue. The idea was initially to produce a paint cleaner that would leave a thin protective coating behind to assist in corrosion protection.

Lanowash was born, and managed to exceed all expectations. Lanowash was able to clean vehicles and leave the most impressive shine. Further developments over the next four years resulted in the release of Ultra Gloss.


Ultra Gloss is used in the normal manner as with most car/truck/boat washes. Being highly concentrated, only a small amount, mixed with water will produce soft, gentle suds.

Ideally the item being washed should be chamoised dry. The gentle pH neutral formulation is guaranteed not to harm paint work, two pack paints and gel coats The microfine layer of lanolin that is left behind will not be detectable by the naked eye, but will assist in guarding against corrosion for up to four weeks.

However… the real impact of using Ultra Gloss will become evident the following day! Ultra Gloss requires between 12 to 16 hours (depending upon climatic conditions) to fully penetrate into the surface. The result is a truly impressive shine. Not just a “wash n wax”, but a deep lustre that is normally only achievable from polishing.

This finish will last for between three to four weeks, and beads well for at least two months.!

Thus Ultra Gloss replaces our popular Lanowash, providing pH neutral cleaning power for all vehicles; prestige to prime mover.

Fuel Fix

Contamination in fuel is far more common than most people realise!


The two most common types of fuel contamination are; water and fungal growth.






Sierra’s Fuel Fix is a highly concentrated additive for the elimination and control of bacteria, fungi and water contamination in fuels. Utilising the latest in microbiological controls and surface active agents, water and biological contamination is harmlessly dissolved and dispersed into the fuel, and subsequently burnt off. Bacteria and fungi such as the common air borne spore Cladisporium Resinae appear as dark “sludge” like particles in the fuel reservoir. At their worst this “sludge” can amount to large lumps or mats. Unlike the many biocide treatments that are on the market that are only designed to kill bacteria, not remove and are of no use in removing water, Fuel Fix will remove the entire problem.

Fuel Fix can be safely used with diesel engines that run a particulate filter, in fact it will improve the efficiency of particulate filters, by dissolving any occurrence of the diesel bug.

Fuel Fix will not affect seals, hoses and fittings within the fuel system. Regular use will eliminate problems associated with condensation, and prevent further biological growth from occurring. This will give rise to;

Improved fuel economy

Smoother acceleration

  • Improved power
  • Improved fuel flow (especially through filters and injectors)

Left untreated, moisture in the fuel tank will eventually cause corrosion, leading to even more problems.




An initial dosage of 2 litres for every 1000 litres of fuel is recommended to thoroughly purge the fuel system of all contaminants. Regular subsequent dosage can then be reduced to as little as 1 litre for every 4000 litres of fuel. At this level of 1:4000, fuel quality will be maintained, condensation will be absorbed, and biological growths will be prevented.

If necessary, a maximum dosage of 5 litres may be added for every 1000 litres of fuel, where bacterial/fungal growth is inhibiting the flow of fuel through the system.

In all cases, Fuel Fix should be added prior to the addition of the fuel.

Since Fuel Fix will attack the existing ‘bug’ that is present, initial dosing will require more frequent cleaning/replacement of filters in the system to avoid blocking. Ensure that all efforts are taken to drain high levels of water first (where possible)

The dark sludge in this fuel sample is Cladisporium Resinae(fuel bug) which can grow at an alarming rate, clogging injectors and filters.
