HG Fensterputzer Window Cleaner, 35 Window Washes, 500 ml

I used to use this with a bucket and squeegee, but decided to give it a go using a Karcher window vac which I've just bought.I used the 20ml sachet which came with the vac as a teaser, the Karcher product did the job, but it would work out expensive as one sachet only did 6 outside windows and a patio window before the bottle was empty, the windows weren't particularly dirty either, but it did seen to need a fair amount of solution to achieve a sparkling finish.The next day I used this solution which only needed a few drops in the supplied spray bottle rather than 20ml, I then did 9 windows and patio window and all the mirrors in the house, at the point the battery needed charging on the window vac, and I still had half a bottle of solution left, clearly this solution is very effective at achieving a streak free finish with the minimum of solution, (did you see what I did there) :-)

What can I say, this gives a streak free finish. I purchased along side a water fed window cleaning system and I am very happy with both. The window cleaner only needs a very small amount mixed with water and it has left my windows clean for ages.It has been 6 weeks since I last cleaned then and only now I think they require another clean, but not desperately so. With my previous cleaners (Mr Muscle etc) and bad weather extra, I would consider the windows would need a freshen up every few weeks, so this is a real improvement.I am really happy with this and have used it inside and out. I don't know if there is some kind of replent contained within the mixture, but the continued/sustained result is impressive.

I’ve had it before it’s good and lasts for a long time. Used as directed leaves no smears.

I have used this with my kit which I bought from amazon and it works fine. You do not need as much as the bottle says aND THIS IS GOOD BECAUSE IT IS EXPENSIVE AND THE POSTAGE ON TOP MAKES YOU THINK TWICE i MAY CONSIDER USING WASHING UP LIQUID WHEN THIS IS GONE iF THE PRODUCT WAS FREE DELIVERY THEN i WOULD GET MORE

Totally Brilliant window cleaner. I use it round the house but I use it more regularly to clean the car windows as the 100% streak free finish is great for car windows and mirrors. I agree with our reviews when they compare it with Mr Muscle etc - this costs a fraction when you consider how far it goes and it does a ten times better job.As an aside, I did actually wash my whole car with it recently - I got a great (streak free) finish!

Absolutely fantastic window cleaner, a little goes a long way. My windows are gleaming, saving money on paying a window cleaner.I would highly recommend this product. I will be buying again when mine runs out ⭐️⭐️⭐️⭐️⭐️

I used this to clean the outside and inside of my windows. I used 3 teaspoons in a gallon on water and was quite amazed at the results. I used a good squeegee to clear the windows and wiped over with a good fibre cloth. There was no evidence of streaks and the cleaning was effortless. The results were so good I’ve bought another bottle.I can recommend this product

I am using this product in conjunction with my hose extension window cleaner brush. Works well. Be warned, this is super concentrated, so a little goes a long way. Start with a pea size amount. It is a good product, I will purchase again.
