It’s a guarantee on almost every glass cleaner, and for the most part, it’s true. I’ve discovered the trick to streak free shine is in the method, not the solvent. I choose not to use any cleaner that has ammonia (Windex), but you can use what you like. Honestly, you can even use multi-purpose cleaners for glass a lot of the time, since most are just water and surfactants. I like to use Method Glass Cleaner or Trader Joe’s green Multi-Purpose Cleaner. You can also use vinegar. There are two tools I keep on hand for mirrors and glass: a squeegee, and the hardest, cheapest, least absorbing paper towels. I’ll explain…
My preferred brand is Ettore. I’ve tried several, but for me this brand works best. And it only costs $3-$5, depending on the size. I have several sizes, but I find I only use the smaller one, so I would go with that. A squeegee is perfect for large bathroom mirrors, glass shower doors, and outside windows. Just spray, swipe, and wipe off any moisture in the surface corners.
My husband will go to the store and come back grinning with nice, soft, absorbing paper towels, and I fall to my knees and wail. No, it’s not that dramatic, but it is on the inside. The softer, more absorbent the paper towel, the more likely it is to leave behind fuzz, causing smudges and streaking. The cheapo paper towels are great at leaving behind nothing. You can also use newspaper, but who regularly has that on hand?
You can also use microfiber cloths:
Microfiber cloths can be great at cleaning glass, but you must adhere to a couple rules of thumb:
1. Only wash with other microfiber cloths. Microfiber cloths are a magnet for fuzz, so washing them with any other material will render them useless as they will leave behind fuzzy streaks.
2. Wash only with water and no detergent. You can add a little vinegar if it needs something stronger.
If you are wanting to clean tv, gadget, or computer screens, the safest thing to use is isopropyl alcohol mixed with distilled water. Just a couple drops to remove smudges and wipe with a microfiber cloth.
I clean our bathroom mirrors once a week and wipe down our smudgy, toddler-peanut-butter-kissed doors and windows several times a week. After wiping down the table and kitchen counters, it just takes a 2 second swipe across the glass and then . . . there it is! That streak free shine 😉
