FAQs
Can Gtechniq W4 Citrus Foam be used on matte paint?
Yes, but it's recommended to use a weaker dilution (e.g., 1:15 or 1:20) and test on an inconspicuous area first to ensure compatibility with specific matte finishes.
Will W4 Citrus Foam remove tar spots?
While W4 Citrus Foam will help loosen tar spots, for heavy tar contamination, a dedicated tar remover might be more effective after the initial foam wash.
How long should I let the foam dwell on the car?
For most pre-wash applications, allow the foam to dwell for 5-10 minutes. Do not let it dry on the surface. Rinse thoroughly before it dries.
Is this product safe for use in direct sunlight?
It is best to avoid using any cleaning product in direct, hot sunlight. Apply to a cool surface and work in the shade or during cooler parts of the day to prevent the product from drying too quickly.
Does this product replace a regular car wash?
No, W4 Citrus Foam is a pre-wash treatment designed to enhance the safety and efficiency of a subsequent contact wash. It removes the bulk of loose dirt, making the actual washing process safer.
What is the shelf life of Gtechniq W4 Citrus Foam?
When stored correctly in a cool, dry place with the cap sealed, the product typically maintains its efficacy for several years.
Can I use this product on convertible fabric roofs?
It is generally not recommended for use on fabric convertible tops, as it may affect the fabric's water repellency or appearance. Use products specifically designed for fabric roof care.
Troubleshooting
Foam is not thick or clinging well.
Ensure the product is diluted correctly. If using a foam lance, check the water-to-product ratio and the pressure washer's flow rate. Colder temperatures can sometimes affect foaming.
Product left water spots after rinsing.
This is usually due to hard water. Ensure thorough rinsing and consider using filtered or de-ionised water for the final rinse. Also, ensure no product residue remains on the surface before rinsing.
Unsure about the correct dilution ratio.
For general pre-wash, start with a 1:10 dilution (1 part product to 10 parts water). For heavier soiling, a slightly stronger mix may be used. For lighter cleaning or if concerned about protection layers, a weaker dilution like 1:15 can be effective.

Setup, Compatibility & Care
Setup & Application:
Gtechniq W4 Citrus Foam is typically diluted before use. The recommended dilution ratio varies depending on the application and level of soiling, but a common ratio for pre-wash is 1:10 with water. It can be applied using a foam lance attached to a pressure washer for maximum foam coverage, or with a pump sprayer for targeted application.
Compatibility:
This formula is designed to be safe for all types of automotive paintwork, including clear coats, and will not affect existing protective layers such as ceramic coatings, waxes, sealants, or polishes. It is also safe for use on plastics and rubber trim.
Care:
Store the product in a cool, dry place away from direct sunlight. Ensure the cap is tightly sealed to prevent evaporation and contamination. Clean any spills immediately with water. After use, rinse the foam lance or sprayer thoroughly.
