Protect Electrical Connectors: 

• Shake the Sonax SX90 Multifunction Oil can well.
• Spray the oil generously on all exposed electrical connectors. This helps repel water and prevents potential damage.

Preparation:

• Ensure the engine is cold before starting. Hot engines can cause cleaning agents and water to act more aggressively, potentially causing damage.

Cover sensitive areas:

• If your vehicle has any open air filters or induction kits, cover them with plastic bags to prevent water ingress.

Dilute the cleaner: 

• For normal dirt, dilute Sonax Multi-Star All-Purpose Cleaner at a ratio of 1:10 with water.
• For heavier dirt, use a 1:5 dilution ratio.

Apply the cleaner:

• Pour the diluted cleaner into a spray bottle or foaming bottle.
• Spray the cleaner evenly over the entire engine bay.

Agitate the cleaner:

• Allow the cleaner to dwell for 1-2 minutes.
• Use a brush to gently agitate the cleaner, reaching into crevices and tough spots. This helps break down dirt and grime.

Rinse Carefully:

• Use a high-pressure washer to rinse the engine bay.
• Keep the nozzle moving and maintain a safe distance from the engine components to avoid damaging sensitive parts with high-pressure water.

Drying: 

• Use a blow dryer or compressed air to blow out excess water from crevices.
• If a blow dryer is not available, you can use a towel to manually dry pools of water. Complete drying is not necessary because the next step involves a water-based dressing.

Apply Dressing:

• Spray the Plastic Care evenly over all plastic, rubber, and metal surfaces in the engine bay.
• The product is water-based, so it will level out with any remaining water, simplifying the process.

Finishing Process: 

• Allow the dressing to dry. It will provide a nice finish and protect surfaces.
• If you notice any high spots or uneven areas, dampen a cloth with the dressing and gently level them out.

• Do Not Use High Pressure Up Close: Maintain distance and keep the nozzle moving to prevent damage to connectors and sensitive parts.
• Cover Sensitive Areas: Always cover any sensitive components you’re concerned about.
• Use a Cold Engine: Ensure the engine is completely cool to avoid potential damage.
