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

Does what it says on the tin, it cleans windows very well. Used with the Karcher window cleaner, its an excellent combination.

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.

The Kärcher Window Cleaner Concentrate RM 500 works well for streak-free cleaning of windows, mirrors, and glass surfaces. When diluted according to instructions, it leaves surfaces clear and shiny without residue. It’s concentrated, so a little goes a long way, which makes the bottle economical for multiple cleaning sessions. However, it requires careful measuring, and using too much can leave streaks or a soapy film. Overall, it’s a high-quality cleaning solution for glass, mirrors, and windows if used properly.

This stuff is MAGIC! I've never found anything that cleans glass and mirrors without leaving streaks - always used to step back and look to see streaks, more cleaning, over and over again, and then it's never streakless and I just put up with it. But this! No streaks whatsover after one go! And you don't need the hand-held machine that goes with it - I just mix a bit with water in a sprayer and wipe with paper towels - always perfect first time! FINALLY!

Having used the Kärcher Window Cleaner Concentrate RM 500 for several months now, I can confidently say it has transformed my approach to household cleaning. This product is nothing short of a revelation for anyone seeking sparkling clean windows without the usual fuss and elbow grease. First and foremost, the concentrate is incredibly effective. A small amount goes a long way, making it both economical and efficient. I was amazed at how effortlessly it cut through grime, streaks, and smudges, leaving my windows crystal clear with minimal effort. The formula is gentle enough not to damage the glass but robust enough to tackle even the most stubborn dirt. Another standout feature is the pleasant, subtle fragrance. Unlike other cleaners that leave a chemical odor, the Kärcher concentrate provides a fresh, clean scent that lingers pleasantly in the air. This makes the cleaning experience not only effective but also enjoyable. In addition, the concentrate is straightforward to use. The instructions are clear, and it mixes easily with water. Paired with my Kärcher window vac, the results are professional-grade, making my home look brighter and more inviting. Overall, the Kärcher Window Cleaner Concentrate RM 500 has exceeded my expectations in every way. Its efficiency, pleasant scent, and ease of use make it a must-have for anyone serious about maintaining clean, beautiful windows. Highly recommended!

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

Good item

Does what it says, leaves windows sparkling.

This is a great product I use it to clean down my kitchen cupboard doors and I only jhave to dita couple of times a year

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

Detergente da abbinare ai lavavetri della Karcher, io in particolare ho il WV2. Il prodotto viene fornito come campione gratuito in abbinamento con il lavavetri e dopo averlo trovato molto efficace ho deciso di acquistarlo in flacone. E' concentrato, quindi va diluito con acqua e con una minima quantità si possono pulire grandi superfici vetrate; dopo alcuni mesi di uso non sono ancora sceso sotto la metà. Pulisce bene e non lascia aloni su vetri e specchi, a patto di riaspirare il liquido con il lavavetri; il profumo è molto gradevole.

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