There some guy on a couple of weeks ago telling us about ecover dish washing and vinegar well tried and worked very well. The mixture was have a bottle of vinegar and one bottle of ecover. Put a couple of squirts on a bucket with water for trad.I also uses it to stray on garage and front doors which I pole off. The other thing if it gets into your brush it does not leave spot marks on glass. If you need more suds add more ecover to the mix eg. 2 bottles.
