Halfords -20 Concentrate Screen Wash is a concentrated formula, with additional detergents and water softeners to enable the breakdown of grease and grime even when the product is diluted up-to a 5:1 ratio with water. Halfords also sells a -20 Ready Mixed Screen Wash which is a convenient formulation that can be poured straight into your washer bottle.
Rated 4.2 out of 5 by 18 reviewers.Rated 4 out of 5 by tommi4891 Obscure pricing on own brand screenwash If you were to do the maths on this, the concentrate pricing appears totally skewed. As another reviewer correctly figured out, the -20 is only achieved neat. So you may just as well buy the much cheaper -20 premix if you're buying for that characteristic. Also we can't just buy the premixed and dilute to get the same results, although the freezing points will be aligned with the ratios on the concentrate bottle, the 'soap' content becomes very weak. That said I tried this route and diluted the premix down to -10 and the cleaning power is just about enough stil. As an added bonus this route also reduces the risk of staining. Regardless of which route you choose, both products perform very well. 09 December 2016Rated 1 out of 5 by Alex1123 Use ready mix To get -20 you have to use it undiluted. Therefor buy the -20 ready mix and use undiluted it is also cheaper!! 19 December 2015Rated 4 out of 5 by plop7272 -20 screen wash the only thing that I have problem is the green colour on the paint work, also it matches, anti freeze and also floor cleaner. Would like to see clear or lighter coloured but it works 18 March 2015Rated 5 out of 5 by SJW1969 Avoid the big freeze It's definitely worth paying a bit more for this stronger version of screenwash. We frequently get minus double-digit temperature in Scotland and none of the pre-mixed options are able to operate at these temperatures. Avoid the possibility of frozen washer jets and getting stuck on the motorway with a smeared windscreen that you can barely see through. Buy the good stuff and don't worry about it. 19 February 2015Rated 5 out of 5 by Bimmerman59 Works the way I wanted Found it to be better value for money than the premix. Wanted to be sure of lowest temperature protection - so far so good! 28 January 2015Rated 4 out of 5 by whitsend Crystal clear screen Whilst I have not been faced with temperatures anywhere approaching the -20 it was very effective at -4 with no freezing of jets or smearing .Will post another review if I experience lower temperatures. 13 January 2015Rated 5 out of 5 by MarkD29 this is the only screen wash that works worth every penny, don't waste youre time with cheap supermarket rubbish! 13 January 2015Rated 3 out of 5 by CheapNotChearful Not the greatest This product is classed as a -20 Concentrated screen wash. However to get -20 protection it must be used undiluted! May as well have called it a -20 ready to use screen wash. Early days yet, but it does not seem to cut through grease as well as other screen was I have used. Smells nice, but the bright green colour takes some getting used to. 10 January 2015
