Understanding Dishwasher Film: What Causes It?
Before diving into cleaning methods, it’s essential to understand why dishwasher film appears on your glasses. According to Maytag, “A cupboard full of cloudy glassware can result from two unique causes: hard water buildup and mineral deposits or etching. Hard water deposits are made up of minerals like magnesium and calcium that cling to dishes, leaving behind a milky residue that doesn’t usually wash off in the dishwasher. Etched glasses have small scratches and dings most often brought on by interactions with soft water and can’t be repaired” [(( Maytag ))].
Hard water is a primary culprit, especially in areas with high mineral content. The Spruce adds, “One of the most common causes of cloudy glass is deposits or spots left on the glass by the minerals in hard water. Hard water is rated according to the volume of minerals (usually calcium and lime) suspended in the water and is found across the United States in varying degrees of hardness” [(( The Spruce ))]. Etching, on the other hand, is permanent damage caused by soft water, excessive detergent, or high dishwasher temperatures, leaving tiny scratches that trap light and create a hazy look.
To determine the cause, try this test from wikiHow: “Rub a drop of white vinegar onto the cloudy surface with your finger. If the cloudiness clears or moves around, you’re dealing with a hard water film. If it stays cloudy, the glass is probably scratched” (wikiHow). This distinction is crucial because hard water film can be removed, while etching cannot.

Step-by-Step Methods to Clean Glasses with Dishwasher Film
Here are proven methods to restore your glasses to their original clarity, focusing on removing hard water film since etching is irreversible.
Method 1: Vinegar Soak and Hand Wash
Vinegar’s mild acidity makes it an excellent solution for dissolving mineral deposits. Whirlpool suggests, “Place glasses affected by mineral deposits sideways in the sink or in a deep dishpan, then cover them with vinegar and allow them to soak fully immersed for 15 minutes. Drain the sink or remove glasses from the dishpan, then gently hand wash them using dish soap and warm water. Quickly dry glasses with a microfiber cloth, as air drying could cause water spots to form.”
Steps:
1. Fill a sink or large bowl with distilled white vinegar (cleaning vinegar works too).
2. Submerge the cloudy glasses fully for 15-20 minutes. For stubborn buildup, rotate them if vinegar doesn’t cover them entirely.
3. Remove the glasses and scrub gently with a soft sponge or nylon net and a small amount of dish soap.
4. Rinse thoroughly with warm (not hot) water to avoid damaging delicate glass.
5. Dry immediately with a lint-free microfiber cloth to prevent new spots.
Martha Stewart reinforces this approach: “Take the glasses out of their vinegar bath and use either a nylon net or plastic scrubber to remove the cloudy film. Next, thoroughly rinse the glasses with hot water until crystal clear” [(( Martha Stewart ))]. This method is simple, affordable, and uses items you likely already have at home.
Method 2: Baking Soda Scrub
For tougher film, baking soda’s mild abrasiveness can help. Cleanipedia advises, “Mix equal baking soda, vinegar and hot water. Soak the glassware in the solution for about ten minutes. Rinse and dry the glass as usual. If the stain persists, repeat the steps.”
Steps:
1. Combine 5 tablespoons of baking soda with warm water and a splash of vinegar in a bowl to create a fizzy solution.
2. Soak the glasses for 10-15 minutes.
3. Scrub gently with a damp sponge dipped in more baking soda.
4. Rinse well and dry with a microfiber cloth.
This method also disinfects, as Cleanipedia notes, “Sodium bicarbonate has antibacterial properties. So while you’re making cloudy glasses crystal clear again, you’re also disinfecting them.”
Method 3: Dishwasher with Citric Acid or Additives
If you prefer using your dishwasher, Consumer Reports tested additives to tackle hard water buildup: “We tested Finish Power Up Booster Agent, Glisten Dishwasher Cleaner & Hard Water Spot Remover, and Lemi Shine Original. When we used the same amount of each product—about 50 grams—all three worked splendidly” [(( Consumer Reports ))]. Citric acid crystals are another expert favorite.
Steps:
1. Remove all metal dishes or delicate items from the dishwasher.
2. Add 50 grams of citric acid crystals or a hard water remover to the detergent compartment (not with regular detergent).
3. Set your water heater to 140°F (60°C) for optimal cleaning without risking etching.
4. Run a normal cycle, followed by a rinse cycle with plain water if recommended.
5. Check glasses for clarity and repeat if needed.
Homes & Gardens highlights citric acid’s efficacy: “‘Citric acid is my go-to for cloudy glassware,’ says Carolina Kazimierski, co-owner and president of Sophia’s Cleaning Service. ‘I’ll either dissolve some crystals in water and soak the glass in it before scrubbing, or put the glasses in the dishwasher and add the crystals directly to the detergent spot and run a cycle.’”

Preventing Dishwasher Film on Glasses
Cleaning is only half the battle—prevention keeps your glasses sparkling longer. Here are expert-backed tips:
- Adjust Detergent Use: The Spruce explains, “First, minerals in the water reduce the effectiveness of detergents, so more detergent may be needed to get the dishes clean. Paradoxically, adding too much detergent with hard water only compounds the rinsing problem.” Experiment to find the right amount for your water hardness.
- Use Rinse Aids: Finish recommends, “Add Finish Jet Dry® Hard Water Rinse Aid to your cycle to help ensure that water droplets that form on surfaces are dispersed before they can evaporate and leave behind any limescale residue or spots” [(( Finish ))].
- Hand Wash When Possible: Martha Stewart’s expert Ron Shimek advises, “Hand washing and drying immediately will help keep your glasses from getting cloudy.” Dishwashers amplify hard water issues, so hand washing avoids them entirely.
- Soften Your Water: Maytag notes, “Glasses that are cloudy from mineral deposits may clean up well with an acid-based solution like vinegar, but they’re still prone to becoming foggy as they continue washing in hard water.” A water softener is a long-term fix.

Additional Tips for Glassware Care
- Delicate Glassware: For wine glasses or crystal, Cleanipedia warns, “Tempting as it is, it’s not advised that you put wine glasses in the dishwasher, as the high temperatures can cause the glass to crack and the humidity can cause the glass to cloud.” Hand wash these with mild soap instead.
- Spotting Etching Early: WikiHow suggests, “If you have soft water, use less dishwasher detergent and don’t let the glasses dry under high heat.” Reducing heat and detergent minimizes etching risk.
- Storage: Finish advises, “We know many people store glasses upside down: having the glass rest on its rim avoids dust and other nasties settling in the glass. But having it stand on its base means the part that you drink from isn’t contaminated by the bottom of a cupboard and runs less risk of getting chipped.”

FAQ: Common Questions About Cleaning Glasses with Dishwasher Film
Q: Why do my glasses still look cloudy after cleaning?
A: If vinegar or additives don’t work, your glasses may be etched, not filmed. Martha Stewart explains, “If you angle the glass toward the light, you’ll probably see shades of pink, purple, brown, or blue. At that point, it’s unlikely you can restore the glasses.” Etching is permanent damage.
Q: Can I use toothpaste to clean cloudy glasses?
A: Yes, but sparingly. WikiHow says, “Use basic white toothpaste (i.e., toothpaste that does not contain gels) with a soft-bristle toothbrush to gently spread the toothpaste all over the inside and outside of the glasses.” It’s a mild abrasive for light film, not a cure for etching.
Q: How often should I clean my dishwasher to prevent film?
A: The Spruce recommends, “Clean your dishwasher frequently to prevent mineral build-up that can deposit on glassware.” Aim for a monthly cleaning with a dishwasher cleaner or vinegar.
Q: Is it safe to mix vinegar and baking soda for cleaning?
A: Yes, it’s safe and effective. The reaction creates a fizz that helps lift deposits, as Cleanipedia’s method demonstrates.
Q: Can a water softener eliminate dishwasher film completely?
A: Largely, yes. The Spruce states, “Unfortunately, unless a water softener is used, glass pieces will become cloudy again after each treatment to get it sparkling.” It’s the most reliable long-term solution.
