The Kranzle snow foam bottle lance provides an alternative way of applying your detergent.
The foam bottle method gives you a fairly thick blanket of 'snow' which hangs on the object a lot longer than the usual method through the standard lance. This gives the detergent more time to work its magic before being washed off.
Foam bottles are available in 1ltr or 2ltr bottles with either 22mm screw connections or quick release.
