This update tackles a problem that surfaced on my recently purchased 2008 Honda Pilot, but it should apply to any car. The windows, particularly the back windows with factory tint, were badly spotted. These spots, noticeable primarily in sunlight, didn't disappear when using some liquid products designed to remove various deposits. This led me to believe the spots were perhaps the result of acid rain.

| Bar Keepers Friend and my old pal, the 6" orbital polisher. |
I searched online and found plenty of advice including using extra fine steel wool (not worth the risk) to remove the spots. There were also some special glass polishers as well, but they were pricey for a product I'd seldom use. I decided to try Bar Keepers Friend (BKF) Liquid—not the powder—which I already had. It was recommended on the BKF website for this task.
I applied the BKF to a clean side window with my polisher and spent about 5 minutes slowly going over the glass. I did not treat the windshield, because I didn't want to get the BKF in all the microscopic chips. I also didn't do the side mirrors, since they might scratch more easily than the glass windows.

| BEFORE: These spots wouldn't clean off with anything, or so I thought. |
 |
| DURING: I spent a couple minutes on the task by this point and saw an improvement. |
 |
| AFTER: I spent a few more minutes with the polisher and ended up with this. |

Overall, this was an easy task and the glass looks great again.
