Ultimate Screenwash is a highly concentrated formula that can be diluted to suit a range of weather conditions， seasons and screen contaminants.


The 500ml container makes up to 8 litres of screenwash and will easily cut through road grime， insect remains and everything else that may end up on your windscreen.


During the winter the dilution can be adjusted to suit falling temperatures whilst maintaining screen cleaning capabilities. If used neat， Ultimate Screenwash remains effective and unfrozen at -45°C!


Suitable for all wash jet types， as well as headlight wash units， safe on paintwork and trim.


How to use:

1. Follow the on-pack dilution table and mix accordingly.

2. For example， Optimum Clean is 1:9. That is 1 part screenwash to 9 parts water. A ‘part’ can be any size， as long as the same part size is used. You could pour 1 full bottle of screenwash into the screenwash tank then refill the bottle 9 times with water and add it to the tank. This would make up 5L of ready to use screenwash.
