Quick, simple, powerful
I've used many different glass cleaners before with varying results and degrees of difficulty in application. I saw a youtube video of this in action where caked on mayonnaise (as part of the test!) was removed with ease so thought I'd give it a go. Pleasantly surprised by the results, it really is effortless to use, quick in application and powerful! It made bird droppings, water spots, oils & other grime disappear in one pass! I'm definitely adding this to my Koch Chemie range as each KC product I used leaves me blown away. Would highly recommend this.
