Full details
This guide is for drivers seeking improved visibility and comfort during wet weather.

FAQs
How long does the rain repellent effect last?
The duration of the effect can vary depending on driving conditions and the frequency of screenwash use. Typically, it lasts for several weeks to a couple of months before reapplication may be needed.
Can I use this in freezing temperatures?
Yes, this additive is designed to be mixed with standard screenwash fluid. As long as your screenwash fluid has anti-freeze properties, the mixture will remain functional in cold weather.
How much should I use?
Each bottle contains two 250ml doses. You should pour one 250ml dose into your screenwash tank at a time.
When will I see the results?
The repellent effect is not immediate. After application, spray your screenwash a few times and allow a day or two for the water-beading effect to become noticeable.
Can I use this with concentrated screenwash?
It is best to use this additive with pre-diluted or standard screenwash fluids. If using a concentrate, dilute it according to its instructions first before adding the repellent additive.
Will this harm my car's paintwork?
The product is formulated for automotive use and should not harm your car's paintwork when used as directed.
Troubleshooting
Water is not beading effectively.
Ensure you have shaken the bottle vigorously before use and have allowed 1-2 days for the effect to fully activate. Check that you have used the correct dose and that the screenwash reservoir is adequately filled.
Streaking observed on the windshield.
This can sometimes occur if the additive is not fully distributed or if the windshield is dirty. Try cleaning your windshield thoroughly and re-apply the additive. Ensure the screenwash is also circulating properly.
Additive seems to have no effect.
Verify that you have added the correct amount (250ml dose per application) and have allowed sufficient time for activation. Some older or heavily contaminated windshields may require initial deep cleaning before the additive can perform optimally.

Setup, Compatibility & Care
Setup:
- Ensure the bottle is shaken well before use.

- Top up the reservoir with your standard screenwash fluid.

Compatibility:
This additive is compatible with most standard automotive screenwash fluids. It is not recommended to mix with de-icer fluids that contain high concentrations of alcohol, as this may reduce effectiveness.
