I installed this on
Alfa Romeo MiTo

Review
Spotted some insect splats that got onto my car's exterior. Getting to know that this M Series Glass Cleaner can clean the insect splats, bird droppings, dusts, 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 these.
