Demon Shot Screenwash Booster, 500 ml, Creates 25 Litres of Screen Wash

Great product always use these and it works perfect smells great, easy to use just mix with water needed

Good value it’s got measurement markers on the side of the bottle you do get 25ltrs out of a bottle and it dose not freeze, not here in England anyway, will always buy this.

Nice smelling Screencast in a handy bottle. Dilute to use.

Good replacement screen wash compared to the more expensive ready mix. Converted to using when required topping up a 5L container

Good stuff , not strong smell , not that cheap but better than Tesco's blue stuff

Great value

I’m not sure, but this is very misleading (in terms of what is written on the product page). The bottle gives you a little bit more information and there are different dilutions depending on what you want. As I wanted this to work in cold temperatures below freezing during the winter, I needed to dilute 100 mL of the screenwash with 1 litre of water. That’s not giving me 25 L with this small bottle as shown! You’d get even less if you were in an area that gets below -10 temperatures. Also. I don’t understand why it says you can just pour this in without diluting on the product page because you wouldn’t pour in the whole bottle and you’d only be able to do that if you already had a substantial amount of screenwash in there. For info, I used half of the bottle and just under 4 L of water. That didn’t even overfill my reservoir. It’s okay value for money and it does smell nice… it does seem to work so I don’t have a problem with the product, only with the description on the page. It’s quite misleading in my opinion.

Since discovering it, I keep re-ordering this and have recommended to friends. It dilutes to whatever the weather needs. Haven’t yet needed to use it neat, but let’s see what this winter brings…

Originally bought for smell of new car washer fluid. Helps fluid not to freeze in subzero temps. I guess you could mix your own with this also but have not tried

Je recommande à 100% sent très bon et nettoie très bien

Works great as a summer cleaner and smells nice.

Nice smell but doesn’t work and windshield wash, barley cleans, I’m assuming it was 100% intended for temperature control but I bought it to make windshield wash, it that’s your intended purpose, look for other options.

Smells great and works good but it is 1:1 for the winter mix, other than that for the money it gets you a good amount of chery scented fluid thats actually kinda refreshing.
