Castrol Techniclean 45 XBC

Castrol Techniclean 45 XBC is an aqueous, low-alkalinity industrial process cleaner designed for precision cleaning of ferrous and aluminium components.
Formulated with surfactants and corrosion inhibitors and free from inorganic salts and formaldehyde-releasing agents, it delivers reliable cleaning performance while supporting environmental and safety standards.

Techniclean 45 XBC is ideal for inter-operational and final process cleaning, effectively removing soluble oils, light-duty neat cutting or forming oils, lubrication oils, swarf, thin corrosion preventive films, and general dirt from machined parts.

Versatile and Compatible

Designed for use in a variety of modern spray, high-pressure spray, and intensive flood wash systems, Techniclean 45 XBC is compatible with Castrol Alusol XBB and Hysol XBB coolant ranges.
When applied after machining with these coolants, the used cleaning solution can be recycled back into the original XBB coolant emulsion, helping reduce waste and operational costs.

Additionally, while optimised for in-process cleaning, Techniclean 45 XBC is also highly effective for machine tool maintenance cleaning, making it a versatile choice across production and maintenance operations.

Why Choose Castrol Techniclean 45 XBC?

Castrol Techniclean 45 XBC is a high-performance, environmentally conscious industrial cleaner that balances precision cleaning, operational efficiency, and sustainability.
Its low-alkalinity, biocompatible formulation ensures gentle yet effective cleaning of ferrous and aluminium components while minimising foam, corrosion, and energy consumption.

Compatible with Castrol Alusol and Hysol XBB coolant ranges, it offers the additional benefit of solution recycling, helping manufacturers reduce waste volumes, freshwater usage, and overall operational costs.

Techniclean 45 XBC is designed for inter-operational and final process cleaning operations of ferrous and aluminium goods, suitable for use in a wide range of modern spray, high-pressure spray and intensive flood wash equipment. This cleaner effectively removes residues from parts and components after machining with soluble oils, light-duty neat cutting or forming oils as well as thin corrosion preventive films, lubrication oils, swarf and general dirt.

Techniclean 45 XBC is designed to be compatible with the Castrol Alusol XBB and Hysol XBB coolant ranges. When applied in cleaning processes after machining with Alusol and Hysol XBB coolants the used cleaner solution can be recycled to the previous XBB coolant emulsion system.

Though the product is particularly developed for in-process cleaning, Techniclean 80 XBC is also well suited for machine tool maintenance cleaning.

Conditions of Use

• Concentration Range (low-pressure spray, flood wash): 1 – 5%
• Concentration Range (high Pressure spray): 1 – 2%
• Temperature Range: ambient – 70 °C
• Spray Pressure: up to 1200 bar
• Water Hardness Range: 0 – 350 ppm CaCO 3 (0 – 20 °dH)

Optimum conditions of use depend on the detailed application requirements and the amount and nature of the soil being removed.

Castrol Techniclean 45 XBC Product Advantages:

• Temporary corrosion preventive film – protects metal surfaces after drying, reducing scrap and improving productivity.

• Minimises excessive foam – reduces risk of cavitation or damage in high-pressure pumps.

• Excellent demulsifying properties – allows easy skimming and extends bath life, lowering maintenance and disposal costs.

• Supports low-temperature cleaning – reduces energy consumption and improves CO₂ footprint.

• Versatile, multi-metal compatibility – suitable in hard and soft water, enabling product consolidation.

• Recyclable with XBB coolants – used cleaning solution can be returned to Castrol Alusol and Hysol XBB systems, lowering freshwater use and operational costs.

Concentrate:

Appearance: Clear, pale to light yellow liquid

Density @ 20 °C: 1.03 g/ml

Dilution:

Appearance (5% in DI-water): Translucent to hazy liquid

pH (5% in DI-water): 9.9

Corrosion Protection (3% in DI water): Grade 0

Concentration Control:

By titration:

1. Pipette 10 ml bath solution in a 250 ml Erlenmeyer flask and add 50 ml deionised DI-water
2. Add 2 drops of indicator solution metyl orange
3. Titrate with hydrochloric acid (c = 0.1 ml/l) until colour changes from yellow to orange-red
4. Calculation: Concentration in % = required ml hydrochloric acid * factor 0.50

Additional Information

In the case of recycling the used cleaner solution into the coolant system the concentration of the emulsion is maintained by adding Alusol XBB or Hysol XBB concentrate up to the set level.
