Best way to remove streaks on the windshield, how to remove liquid wax?

Clay bar would be best way to thoroughly remove the sealant.

Using regular dish soap mixed with water as your clay lube will also help to remove it. (also saves a lot of money instead of using regular clay lube)

Just wondering, did you apply our Hybrid Wax afterwards?

Before you clay bar, I would first try to fix the problem by spraying a very small amount of Hybrid Wax.

Sometimes streaks may occur with the Hybrid Wax if too much is applied so maybe try this out first.
