Zentox: neutral concentrated degreaser to keep your transmission like new

The transmission is one of the most demanding assemblies of any bicycle: chain, chainrings, sprockets, and derailleurs accumulate grease, dust, and dirt with every kilometre. To clean thoroughly without damaging the materials, Sisbrill developed Zentox, a pH neutral degreaser with a concentrated formula that removes the most ingrained dirt with minimal effort and without compromising any parts.

Main features

• Neutral pH: suitable for any type of material, including chrome, plastics, rubber, and seals. It does not cause corrosion or deterioration on any surface.
• Concentrated formula: a single 1-litre bottle yields up to 10 litres of diluted product, making it a very efficient and economical option.
• High degreasing power: dissolves grease, old lubricant, and adhered dirt without the need for intensive scrubbing.
• Protection against oxidation: its additives act as a protective barrier on the metal components of the transmission after cleaning.
• Solvent-free: safe on plastics and rubber parts; does not attack seals or covers.
• Versatile: also suitable as a general shampoo for bicycles or motorcycles, diluted in water.

Instructions for use

As it is a concentrate, dilution is adjusted according to the level of dirt:

• General cleaning of the bicycle: dilute at 10% (100 ml of Zentox per litre of water).
• Chain and transmission with moderate dirt: dilute at 20%.
• Intense or ingrained dirt: apply the product undiluted directly.

1. Wet the entire transmission with water before applying.
2. Spray Zentox onto the surface to be cleaned and let it act for 3 to 5 minutes.
3. Scrub if necessary and rinse thoroughly with water.
4. In case of persistent dirt, apply directly without dilution.

Recommended applications

• Cleaning of chains, chainrings, sprockets, and derailleurs.
• General degreasing of the bicycle or motorcycle.
• Cleaning of plastic, rubber, and metal components without risk of damage.

Available formats

Zentox is available in 1 litre and 5 litres formats, so you can choose the quantity that best suits your usage rate or the maintenance of multiple bicycles.

Frequently asked questions

Can it damage the chrome, plastics, or seals of the bicycle?

No. With a neutral pH and no solvents, Zentox is completely safe on any material: metals, chrome, plastics, and rubber. You can apply it with complete peace of mind across the entire bicycle.

How much diluted product do I get from 1 litre of Zentox?

With a 10% dilution (general use), you get up to 10 litres of ready-to-use product. For more intensive transmission cleanings, the dilution is higher, but even so, the yield is very high.

Can I use it as a shampoo to wash the entire bicycle?

Yes. Diluted at 10% in water, you can use it just like a shampoo for bicycles or motorcycles, applying it over the entire surface and rinsing with water.

Is it necessary to rinse with water after application?

Yes, it is recommended to rinse thoroughly after cleaning to remove both the product and the dissolved dirt. This ensures a clean transmission ready for lubrication.

Can I apply it to the chain without removing it?

Yes. You can spray it directly onto the chain mounted on the bicycle, let it act for a few minutes, and rinse. For optimal results on very severe dirt, cleaning with the chain removed and soaked is always more effective.
