Better than Fairy Liquid,
Verified Purchase(What is this?)
This review is from: Kärcher 500ml Glass Cleaning Concentrate For Window Vac (Tools & Hardware)
After the original sample run out I was quite shocked at the prices the local stores were charging. Using soapy water and a bucket just seemed to defeat the object of getting the Vac and applicator in the first place.
Well without a doubt it was worth the purchase. A cap full and a half to every applicator bottle so I would think it's good for at least 10 refills so far cheaper than the sachets. Best of all windows now sparkle once again.
Shame Amazon haven't set this up as subscribe and save.
