Thick nail polish, be it metallic nail polish or shimmer nail polish, has uneven consistency. Here’s how to thin out nail polish that has gotten thick, clumpy, and impossible to apply. These methods are a great fix for restoring the original consistency of your polish (even glitter or neon nail polish).

Method 1: Try A Nail Lacquer Thinner

Using a professional nail lacquer thinner is the best way to restore your old nail polish. Here’s what you need to do: use an eyedropper to pour 2-3 drops of thinner into the nail polish. Then, screw the cap back on and roll the bottle between the palms of your hands to mix the two together. Test the consistency – if it flows smoothly from the brush, it is ready to use. If it does not, add some more drops of thinner and test it out again.

If your nail polish is a gel formula (the ones that are UV-cured), use a thinner that is specially designed for gel nail polish. You can also use acetone-free and non-toxic thinners that you can find in most beauty stores.

Method 2: Hot Water Fix

If you are out of nail lacquer thinner, here’s how you can thin out nail polish with things you already have at home to do your manicure and pedicure.

Immerse your bottle of dry nail polish in a bowl filled with hot water, and you have your DIY nail polish thinner ready. Leave the bottle in the water for about 3 minutes. Then, gently roll the bottle back and forth between your palms to shake the polish in it. This method also helps loosen the cap of a hard-to-open nail polish bottle.

Note: As the glass bottle can get very hot, handle it with care and caution. If the polish still does not reach the desired consistency, repeat the process for a few more minutes.

Method 3: One Drop Of Pure Acetone

You can also use pure acetone as a last resort if you run out of nail polish thinner. The key is to only use one drop of acetone as any more than that will break down the nail polish and lessen its lifespan.

If you don’t have pure acetone on hand, but have a nail polish remover that contains acetone, you can use it instead. However, just like pure acetone, don’t use too much of it or it will break down the nail polish color.

You can use an eyedropper to dispense the acetone or nail polish remover inside the nail paint bottle precisely, as too much of the solution will only ruin the color and texture.

Method 4: Rubbing Alcohol

Rubbing alcohol is also a great option for thinning clumpy nail polish. Add two drops of rubbing alcohol to the nail polish. Give the bottle a shake to mix the polish and check the consistency. Add another drop if needed and repeat the process.

Worried that your favorite nail color is starting to harden? By following the easy tips given below, you can prevent your nail polish from getting thick and clumpy altogether. Check them out!

How To Keep Your Nail Polish From Turning Goopy

  • Store your nail polish in a cool, dry place that maintains a consistent temperature (like a drawer just for your beauty products).
  • Wipe the neck of your nail polish bottle with a cotton ball soaked in acetone before you screw the cap back on, especially if it’s a quick-dry nail polish. This also makes it easier for you to open the bottle the next time you want to give yourself a mani/pedi.
  • Never keep your polish close to a source of heat or in direct sunlight.
  • Avoid storing your nail polish in the bathroom as the temperature is constantly fluctuating in there, and humidity is your nail polish’s #1 enemy.
  • Store your bottles the right way by keeping them upright. If you store them upside down or on the side (please don’t throw them haphazardly in a drawer), it will cause clumps in the formula and dry at the neck of the bottle.
  • Don’t leave the lid off for longer than necessary. Exposing your nail polish to air is one of the top reasons for the thickening of your polish. It’s best to close the bottle between coats.

Applying nail polish with the fan is advisable to keep it from drying out. You can also cover the lid while using the color.

A new bottle of nail polish is delightful. The only thing that beats it is knowing that an old, dried-up bottle of your favorite nail polish is salvageable. Follow these steps on how to thin out nail polish to make them as good as new for a few more coatings. Why throw out bottles when the content is still usable? However, everything has an expiry date. Nail polishes usually last for at least two years (even the long-wear ones), but their chemical formula starts breaking down a few months before the date. So, if your nail polish starts to clump stubbornly and does not blend well, it is time to toss it out.
