How to Make Your Own Rinse Aid

🌱 DIY Green Cleaning Recipe
By Analisa from Under Your Sink

 

If you’ve ever pulled a glass out of the dishwasher only to find streaks, spots, or that cloudy film, you’ve probably reached for commercial rinse aids. They promise sparkling results - but at what cost? Hidden chemicals, unnecessary packaging, and yet another bottle under your sink.

The simplest swap you’ll ever make? White Vinegar or a Citric Acid Solution

They are both  naturally acidic, which means they cuts through the alkaline mineral deposits (think calcium and limescale) that leave your glassware looking foggy. It also helps water sheet off surfaces instead of drying in droplets that cause spotting. 

Commercial rinse aids often contain synthetic surfactants, dyes, preservatives, and sometimes fragrances. These end up washed down the drain, adding to the chemical cocktail in our waterways. The irony? You don’t actually need them. A splash of vinegar does the job without the extras.

 A Few Tips for Best Results

  • Use plain white vinegar - not apple cider or balsamic (unless you want your dishwasher smelling like a salad).
  • For a Citric acid solution, just dilute a teaspoon into 100ml of warm water
  • Still seeing cloudy glass? That’s usually hard water buildup - try giving your machine a clean cycle with vinegar as well.

This is the easiest green cleaning swap you can make - no recipe required.

    You can add a few drops of citrus essential oil can give your rinse cycle a fresh scent. Just don’t go overboard, as oil and water don’t mix perfectly and it can build up if you add too much.

Common Questions

Will vinegar ruin the seals in my dishwasher?

The word on the street is it will ruin the seals because it's acidic. If you research the pH of most Rinse Aids they range from 2-6 making them all acidic solutions. Corrosion will occur over time no matter what, that's why we need to clean & maintain the dishwasher but please only do what you are comfortable with.

What exactly does rinse aid do, and why is it helpful?

Rinse aid helps water slide off your dishes instead of drying in droplets. That means fewer water spots, better drying, and shinier results - especially on glassware.

Can I mix homemade rinse aid with commercial products?

Best not to. Mixing can sometimes reduce the effectiveness or cause unexpected reactions. Pick one and stick with it for each cycle.

What if I still see water spots or cloudy glasses?

Try adjusting your rinse aid concentration or reducing the amount of dish powder. Also a good idea to heck your dishwasher’s spray arms and filters for blockages.
