Glass Renew - 8 oz - 3 Pack (Removes Hard Water, Dirt & Debris)

Requires a bit of elbow grease, but will deep clean the pores of your glass. Did you know.... truly clean glass does not bead water! It actually sticks to the glass. When you run your wipers and see haze, you are probably seeing some micro beads of water too. In order to remove this, you need to deep clean the pores of the glass. It's not an easy task and requires some elbow grease but it's worth it. My wipers glide smoothly over the glass and create a clean wipe each time.

My car windows were full of water spots and gunk stuck to them. This step is not necessary but I used a clay to get rid of the stuff stuck to the glass. Then just wet the glass as directed and applied the product with microfiber, cleaned it, and reapplied on a few spots that needed extra work.It was pretty easy and the Glass Renew did a good job. A small amount goes a long way.

I bought this product based on the review it has...But as you can see on my pic, it was not able to remove some basic hard water spots which was my reason for buying it.Neither by hand or with an electric polisher.I used a full bottle on my boat windshield to remove maybe 15% of the stains after 2 pass!!To bad i can't return an empty bottle,

Loved that this product was exactly as described
