Review
I am glad I got this the other day while shopping for my car's needs. I had just got home from visiting site, and there were some insect splats that got onto my car's exterior. Getting to know that this Liqui Moly Window Cleaner Super Concentrate can clean the insect splats, along with giving the protecting coat that repels rainwater, I went ahead to try it. Insect splats and stains were easily removed within a few wipes, and also after applying a few coats on my windscreen, I noticed that rainwater were repelled effectively when driving through the rain. They roll off my windscreen almost like I applied a layer of wax/oil. Now, I can comfortably have a good view of the front without the annoying raindrops blurring my view.

What I like
Effectively cleans stains and repels water.

What I do not like
After my first bottle finished, I went around looking for another bottle. I must say it was quite tough to find a bottle of this.
