Ingredients UNGER's Liquid Window Cleaning Soap

Review: Really clean and almost completely streak free - This product is great. Compared to other brands, there is less streaking etc. Water runs off moderately well, I wouldn't say anywhere like a wax does on a carwash, but it is close enough. I'm still looking for something that leaves no streaks from the telescopic brush I use but for now this is the best there is. Easy to use, just dilute as directed. Price is on point really but I'd like to see it work better as we have hard water. Bottle size lasts several years, we have around 40 windows and I wash every 5 or 6 months due to this being a real chore, so it's lasted 2 years. Pretty good tbh.
Review: Strong and easy to use - Great cleaner - used only once on very dirty windows and make quick work of all the dust and grease. Still got 90% of the bottle left as a little goes a long way!!

## Questions & Answers

**Q: When diluting in water what is the ratio of product to use per litre or bucket?**
A: The dilution ratio given on the FR100 details on Amazon, on the Unger web site and on the bottle I have is 1:100. This equates to1 part of Unger Soap to 100 parts of water. Therefore you add 10 ml of Unger soap to 1 litre of water, or if you have a 5 litre  bucket then you would add 50ml of Unger soap to make up the solution. 
Hope this helps.

**Q: Does this contain alcohol my windows have film on them so needs alcohol free products**
A: No this does not contain any alcohol. It should be safe to use on the film.

**Q: What's the secret to a streak free finish please?**
A: I always rinse the glass with rainwater before finishing off with a professional quality rubber squeegee. I use a pump-garden sprayer and spray the rainwater using that.

**Q: Can this be used in a Karcher vac window cleaner ?**
A: An interesting question. As the Karcher window cleaner is in a spray bottle, it would be sensible to think that you can use any sprayable window cleaner fluid. All you should need to do is to dilute the Unger window cleaning fluid as required and fill the Karcher spray bottle. Worth trying it out to see if it works.
Hope this helps.

Great cleaner - used only once on very dirty windows and make quick work of all the dust and grease. Still got 90% of the bottle left as a little goes a long way!!

### ⭐⭐⭐⭐⭐ AMAZING, VERSATILE AND EFFECTIVE PRODUCT
*by J***D on 31 July 2025*

Exceeded all expectations. I mixed with cold water and it was ready to go. I washed over windows and PVC with the solution then dried with a microfibre cloth. Gleaming! I used inside and out. I also used on my bathrooms and to clean my kitchen cupboard doors, which are high-shine. The solution even has a nice, fresh smell. It's a 1/100 dilution but I wasn't too exact, but it's economical. Can't find a negative thing to say about it.
