Flow Blue 5:1 Concentrate Vehicle Screenwash | All Seasons Formula | Effective down to -5°C | Streak Free Finish (10 Litre)

I always buy concentrate, as its diluted 5 parts water to 1 part concentrate. Why pay for ready mixed as its 80% water, when concentrate gives so much more.The mixed ratio gives good cleaning powers and help dissolve bird droppings. I find it easy to use and very economic, smalls good too.

Great value for money and works fine. I did originally get sent the wrong item but it was super easy to get in touch with the company and get the right one sent out.

so far so good

Glad to say works well & mixed god .

Windscreen wash

Bought four 5 L bottles thinking that they were a mix of 20:1 as my usual screen wash is.They're not. They're 4:1 so nowhere near the same value for money.I can't remember seeing anything about the ratio mix on the pre purchase description.Slightly disappointed.

I keep old 5l containers (such as these, but used for other things such as deionised water) and make up a batch of 5 containers each containing 1L of concentrate and 4L of water. 5 of these will keep you in screenwash for a year, topping up as required, so you can see the amount of savings that you make by simply adding your own water. At this level of concentrate it cleans effectively and I have experienced no problems with freezing.

Delivery made by Royal Mail ETA exceeded. As would be expected package was quite heavy but manageable.
