I too have been following this thread since the start. I have used all the usual detergents inc squeegee off, gg3, gg4, fairy, stardrops, unger liquid and others yet have never found one that had good glide along with  no residue, it always seems that one is sacrificed for the other. I had settled on unger liquid used with unger hard rubbers, the glide is pretty good and has very low suds so cills are easier. Recently though i noticed after cleaning some ins n outs that the unger is leaving a film that can be seen in the sunlight, especially from the inside, not on all houses but enough to make me look for something else. It seemed for me in a hard water area that getting a detergent that is good in all aspects that we need is nigh on impossible! So I have followed this thread with interest and have been prompted to try it myself.
I am now on my 3rd week. I wasn't too sure in the 1st few days what I thought, it seemed as good as anything else but not spectacular as is being said (the smell of vinegar was very strong using the amount recommended and I would not use it inside someone's house). I then started varying the ratio of Eco to vinegar. At the moment I am using 20 ml of Eco and 30ml of Sarsons clear malt vinegar (tesco 40p). I'm still not sure though about it though. There are a lot of suds with just 20 ml of eco (which is a lot less than the 2 x 2 sec squirts recommended) thus more time taken and cloths used wiping cills. The glide is pretty good though not really any better than using unger liquid, it can still stick a little at corner turns etc. Where it comes into its own I think is in the job it does of cleaning along with from what I can tell, very little residue. The glass does seem cleaner. Another negative I came across this this week though is a bit of water 'creep' on the edges of the glass  in the early morning colder weather. This may be a big problem during the colder months and would definitely put me off if it, nothing so annoying as glass creep in the cold.
I will continue to experiment with ratios and definitely keep using it for a few months (as long as the glass creep doesnt get worse) to give it a good go, see what its like on follow up cleans etc.
I reserve judgement for now.
Would be good if others who have used it give their opinions, hard or soft water area, what ratios used and results etc

Tried both karl without doubt the washing up liquid is much better!

In general,I`ve got to agree with WhoStolemyHair on this.
Although hav`nt had any time to experiment on the WFP
Side of things.
The smoothness of the glass and general `slip`of the rubber
Is great I find.No residue will always be a bonus too.

PS.   don´t add anything to it  your  just defeating the object.if you need something stronger  for another job then just use  your normal  soap.. if you start adding your killing its  potential advantages..

Thanks buddy, you're the first whose tried both that could tell me this.

Just letting you know that Ecover washing liquid is half price in tesco ( £1.50 for a 1 ltr bottle)

its  1.75 €  here  which is pretty  much the same price . but also  included  of late is          "  50 %  extra  free  "  so my  bottle  has  750 ml  and cost 1.75 €

Yep! Tesco are selling 1 litre bottles of Ecover for £1.50 (not 500ml or 750ml)

Been doing a bit of testing myself and have come across a product that is added to your mix and makes the glass shine like you have never seen before!

It is the best shine i have ever seen! absolutely stunning shine!

Much better than the ecover shine! all i have to do now is wait and see how long it stays clean for to see if it will match ecover!
it is so good my customers have all been talking about the shine on their windows and asking what i used, but told them trade secret!

honestly this stuff is phenomenal,

plus i have found a cleaning liquid that contains no soap!

happy days!

ps. if this stuff works with wfp as well then it will be the end for ecover! it is really that good.
ecover sales will drop like a ton of bricks! oh dear!

well jeff as there is no soap in it i am hoping!

Honestly using this stuff customers look as though they have had new windows fitted the glass is gleaming!

I am curious to see how this stuff performs.  I don't actually use Ecover as I use a soap that outperforms it in terms of shine, HG Window Cleaner.  The shine you get with HG is amazing, so I am interested to see if it can be topped.  We'll have to wait and see.  I don't understand what the big secret is, are you hoping to take out a patent on it or something?

On the subject of 'spotting' I came across something interesting today.  8 weeks ago I was cleaning the windows on two different houses that both had bug droppings on the glass.  I thought I'd try and use some HG UPVC Cleaner on it, since it is VERY powerful, and gets bug droppings off PVC with no effort at all.  It worked great on the glass too, they came straight off, so I thought I'll bear that in mind for the summer when I have to deal with them every day.  Anyway, 8 weeks later, today, I went to do the two houses again, and found that the windows were spotless.  Shiny, no rain spotting or anything.  Seriously they were so clean I could have just not bothered cleaning them (but I did of course )  Both houses were exactly the same.

A coincidence? Maybe.  I'm going to buy another bottle a see how it goes.

Used ecover for the first time this week im inpressed it may cost more but you use less about half as much than fairy
