so how important is it to measure it out before throwing in the bucket?
with fairy i just put a bit in that would do - can it be the same for gg4?
will it be much different to using fairy - i do like blading a nice wet n soapy window
wont get much suds with it , i use gg3 plus a window cleaning solution i buy locally, works great , better to add another cleaning solution to ggs-gg4,
on its own you have to use at least double the recommended dosage , works out expensive then.
