4. Wipe clean
Use a folded paper towel to wipe clean the crack.
5. Clean the edges
There are places that you can’t simply clean because they are hard to reach, but you can drop the paper towels and grab some cotton swabs. Simply take a cotton swab and run it along the cracks and edges until there’s no more dirt. If a cotton swab gets dirty, then use another one.
6. Congratulations, you are done
Congratulations, you are now finished, the cleaning process is done and now you can enjoy clean windows again, but make sure to clean them every once in a while.
