Excellent. Exactly what I wanted, at a good price with good service

I’ve been using this de-ionised water for my new iron. As I destroyed lots of irons by using tap water, when I got a new one I wanted to do things properly and bought this one. It’s already my 5th purchase and I’m so happy with it. You get a lot of water, great value for money. I tried using other brands too but this water by far is the best. It’s properly de-ionised and doesn’t leave any residue.

Good value

This is a very good product especially for my generator iron! But I was buying on subscription for a while, then started saying it wasn’t available, & now I see it’s back…… but more than double the price!!!

I’ve been using Carplan De-ionised Water for a mix of tasks—from prepping car panels to topping up batteries and even in my steam iron—and it’s consistently delivered great results. The water is ultra-pure, with all minerals and impurities removed, so I never worry about scale buildup or residue. For car detailing, it’s brilliant. I use it during panel prep to avoid water spots and streaks, especially when drying surfaces. It’s gentle on paintwork and glass, and leaves a spotless finish when used with microfiber cloths. Also ideal for battery maintenance—no corrosion issues, and it keeps things running smoothly. In the house, it’s perfect for steam irons. No furring, no clogging, and it helps extend the life of the appliance. I’ve even used it with a humidifier and it works just as well.

Very good

Bought this mainly for topping up batteries and using in a steam iron. The 5-litre container is a useful size, the water is clean and ready to use, and it saves messing around with tap water where limescale could be an issue. Nothing exciting, but it does exactly what it is supposed to do and the larger bottle works out more convenient than buying lots of smaller ones.
