When diluting in water what is the ratio of product to use per litre or bucket?

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.

Does this contain alcohol my windows have film on them so needs alcohol free products

No this does not contain any alcohol. It should be safe to use on the film.

What's the secret to a streak free finish please?

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.

Can this be used in a Karcher vac window cleaner ?

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.
