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

This was my first time trying a window cleaning concentrate like this, and it's been a pleasant surprise. It's very easy to use – just dilute a small amount with water as directed, and you're ready to go. One bottle makes a large amount of cleaning solution, so it feels like good value for money. I've used it on windows, mirrors and shower screens, and it cuts through fingerprints, water marks and everyday grime with very little effort. The finish is impressively clear, with no noticeable streaks or smears left behind, even in direct light. The scent is mild and fresh, which I much prefer to some of the stronger glass cleaners that can be quite overpowering. The concentrated formula means a single bottle should last a long time, and it works brilliantly alongside Kärcher window vacs. A simple, effective cleaner that delivers excellent results.

My wife has cleaned windows with a solution of white vinegar in water, so she was skeptical that the Karcher fluid would work on the exterior glass. Outside: Velux windows in the roof, big patio windows, clean and streak free with the Karcher fluid. No more vinegar and water, and the Karcher Window Vacs are great on the windows, shower glass and tiles, and removing water from the car when I've washed it.

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.

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!

Good stuff. Ideal for the window vac. I also use it in a bucket to clean my car windscreen both inside and outside. Nice smell as well. Not to overpowering.

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!

Really great cleaner I second its own without the karcher as the karcher leaves it streaky .

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.

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!

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 have tried so many window cleaning products to tackle all the windows in my business and I finally found a winner! I don't know what is in here but it works. I had to use ai to translate the label and dilution instructions but it was so worth the effort. I use a large manual pump sprayer and a squeegee and the windows are crystal clear. I won't buy anything else going forward. Thank you.

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