Concentrated screenwash is used to clear dirt and other materials off the car windscreen to improve visibility. Unlike ready-mixed screenwash, concentrated screenwash needs to be mixed with water prior to use. Having added the correct proportion of water to the mixture - which varies according to the size of the bottle and the product itself - you can then add it to the washer fluid reservoir and use it as and when required to clean your windscreen. A lot of people opt for concentrated screenwash for financial purposes, others prefer it to ready-mixed screenwash because they feel that the solution is stronger and it will therefore clean the glass more thoroughly. Whatever your reason for choosing concentrated screenwash Euro Car Parts keep a comprehensive range of products in stock, all of which are available for fast home delivery or click and collect.
