Here is some tips that can help.
Tip 1 – Go from top to bottom
If you really want your window or mirror to be streak free, clean from top to bottom. Begin at the top and work your way down to make sure that no drips will happen on the glass surfaces that are already perfectly cleaned.
Tip 2- Use a Squeegee
It’s amazing what a difference this one simple tool makes on glass. Having to rewipe areas of glass is a guarantee that you’ll have streaks. Using a squeegee makes it effortless to polish each section of the window. A long handled squeegee is a must if you’ll be doing tall windows, and it will do double duty in cleaning shower walls as well.
Tip 3: Metho & Water
Mixing Metho with water can be a useful way of cleaning your window. A Metho-water solution (50/50) works great — just spray or wipe it on like you would any other cleaner.
Tip 4: Banish Paper Towels
Paper towels leave not only streaks, but linty ones. Instead, go for a microfiber cloth, a squeegee, or, best yet, a handful of newspaper. Your morning read does an amazing job on glass.
There are many people who love to use newspapers to polish their glass surfaces. It does work and can work well, but many people don’t like getting newsprint on their hands. The newspaper also doesn’t hold up very well when it gets wet. But it’s worth giving it a try.
Tip 5: Wash windows on a cloudy day
The sun can prematurely dry the window wash, leaving residue and streaks. Wait for a cloudy day to wash your windows and you’ll end up with a brilliant streak-free shine.
Tip 6: Clean corners with a cotton swab
No matter how hard you try, residue seems to buildup in the corners of our glass. It can be very difficult to get to that residue, unless you have the right tool. Try using a cotton swab to clean those hard to reach areas of the windows in your home.
