Kärcher Window Cleaner Concentrate RM 500, for Streak-Free Cleaning of Windows, Glass, Mirrors and Shower Screens, 500ml Concentrate dilutes to 4l Cleaning Liquid.

After diluting and applying the solution, I found that many of the marks (fingerprints, light smudges, general dust film) came off easily. The product lives up to its “streak-free & water-repellent” claim for these kinds of deposits. • It has a reasonably pleasant scent (not overpowering) and felt safer to use around the house than some harsher glass cleaners. • Because it’s a concentrate, a little goes a long way — good value in terms of coverage. • Combined with a decent micro-fibre cloth and a squeegee (or a proper window vacuum), the finish can look quite sharp and clean.

Good item

Kärcher Window Cleaner Concentrate RM 500, This formulation is 500ml which when diluted you should get around 4 litres of cleaning solution. Ive used this solution a couple of times and i will say the streak-free claim is fairly correct when using the window Vac although there are some streaks around the edges. The smell isn't over powering the fragrance is just a fresh scent which is pleasant without smelling some what chemical. This is perfectly suitable on many types of surfaces so Ive used for the shower, mirrors windows and car in order to remove some stains and grease and Ive been fairly impressed with this product. Overall some what predominately streak free, cost effective when diluted, no harsh chemical smell, easy to use when using the Window Vac.

You only need a little of this, works very well leaving you with clean streak free windows/glass

Excellent Purchase - Would Buy Again

I bought this cleaner to use with my Karcher window vaccuum. It left streaks so I decided to try ordinary washing up liquid instead. It did a far better job and is a lot cheaper.

Mal ehrlich, hätte mir letzte Woche jemand gesagt, dass Fensterputzen Spaß macht, hätte ich ihn zwangseingewiesen....! Wir haben ein Haus mit einer hohen Fensterfront bis unter das Dach. Sieht toll aus - ist blöd zum Putzen. Aber über dieses Problem habe ich mir nicht wirklich Gedanken gemacht als uns unser Architekt die Pläne zeigte. Egal, gebaut ist gebaut und für die Putzerei würde mir schon noch was einfallen. Jetzt nach 4 Jahren und spektakulären Fensterputzmanöver habe ich mir endlich den Fensterreiniger (Fenstersauger) von Kärcher gegönnt. Der WV 5 Plus sollte es sein, da ich nicht gleich das ganze Gerät entsorgen möchte, wenn der Akku leer ist. Und gleich noch einen Akku mitbesellt und den Verlängerungsstab mitsamt der Putzflüssigkeit. Sicher ist sicher! Heute ist er angekommen und ich musste ihn gleich ausprobieren. Was soll ich sagen - ich konnte nicht aufhören mit Putzen. Verrückt, ich weiß und ich bin mir sicher, wenn mein Mann dieses Teil in die Finger bekommt, dann kloppen wir uns darum, wer das streifenfreieste Fenster hinbekommt, denn schließlich ist Technik damit verbunden und Männer brauchen einfach einen spielerischen Anreiz. Die Fenster werden echt sauber, es geht schnell, der Akku hält lange, die Handhabung ist kinderleicht (wenn man ein bisschen ausprobiert hat) und so schnell war ich noch nie fertig. Nach der Waschmaschine, der Spülmaschine, dem Trockner und der Mikrowelle eines der besten Erfindungen ever!

I love it. Leaving no traces on windows

The cleaner for use in conjunction with the Karcher window cleaner arrived exactly when I was advised that it would. Happy to purchase from this store again.

I like it very much ,my windows are wonderful clean and shinning.

I have a dog and cat in my house so there are a lot of nose prints on my windows. This cleaner cuts right through it with no hard scrubbing. A most have for windows.
