You have finally written down your shopping list and it’s a proud moment. You are about to head out the door and as you reach for your list, a cup, that was once thought empty, has now spilled water all over your grocery list. 

The ink starts to run, and all that time you spent creating the shopping list now seems in vain. Are there waterproof pens to keep this awful event from happening again? 

Pens can be waterproof and water-resistant. There are special pens that have been created to be highly water-resistant to help prevent the ink from running when wet. 

Many of these water-resistant pens do take a while to dry. While waterproof pens may have been around for a while, they recently started gaining popularity in the watercolor world. 

You need a pen that won’t run when the paper gets wet. Waterproof pens can often be found in the crafting section.  

How Do You Revive Ink? 

Almost everyone has reached for a pen only to find out the ink is dried up. You go to write, but no ink is showing up. You can clearly see that the pen still has ink but is refusing to write. 

Here are a few different ways you can revive the ink and have a like-new pen. 


You can remove the ink and blow at one end to push the ink forward to the tip. You can either blow the ink down the tube yourself or even use a can of WD-40 to help push the ink down the tube. 


Often the reason for the pen’s uselessness is due to a dried pen tip. You can remove the dried ink by rubbing the pen on the sole of your shoe, a damp cloth, or even an emery board. 

Once you have scraped away the dry ink, your pen should write well again. 


Another way to remove the dried-out ink is with fire. Take a lighter and get the tip of the pen hot. The fire melts the dried ink right off and loosens the ink in the pen for a better flow as well. 


You can soak the tip of your pen in a cup of hot water or even rubbing alcohol. The warm water will help to remove the dried ink and just like the fire, get the ink warm and moving. 

If after trying these tips your pen still isn’t writing, then you might be able to replace just the ink cartridge in the pen.

What Household Items Can You Use To Make Ink? 

Writing apparatus have been around for centuries. Whether it was a chisel and hammer or ink and paper, writing has always been a part of our history. 

Is there a way to create your own ink at home like the great writers of the past? 

You only need a few items to create your own ink. You can use berries for reddish-tinted ink. For a more natural ink you can use some walnuts. 

To make ink from berries you just need ½ cup of fresh or frozen berries and push them through a strainer to get pulp-free juice. Add ½ teaspoon vinegar, to make sure the color holds, add ½ teaspoon of salt for preservative, and mix well. 

Any type of small glass can be used as your ink well. 

For a more natural colored ink, you can use walnuts. Crush the shells of about 12 walnuts. Put the shells in a saucepan and cover them with water. 

Allow the shells to simmer for about a half-hour. Remove from heat and let the walnuts soak overnight. Strain out the remaining shells to separate them from the ink. Add ¼ teaspoon of vinegar to the ink to help preserve the color. 

If you prefer invisible ink and want to leave clues and messages like in National Treasure, then all you need is lemons. 

Take some lemon juice and use a Q-tip to write. Dip the Q-tip in the lemon juice to write your secret message. 

Once the ink has dried, all you need is heat in order to see your writing. You can also use equal parts baking soda and water to create invisible ink as well. 

In order to reveal your message, brush a bit of grape juice over the ink. 

Why Does My Pen Not Work When There Is Ink In It?

 Pens typically have enough ink in them to write for two miles long. That is a lot of writing; however, most pens do not last nearly that long. 

The reason your pen isn’t working depends on the type of pen you are using. 

Ballpoint Pens

Ballpoint pen ink is thick and oil-based. The ink is known to dry faster than other inks and can become a paste inside the pen. 

Ballpoint pen ink is prone to clumping and you can end up with a few clumps throughout your ink cartridge. 

You can often fix this by scribbling and trying to get the ink flowing. If scribbling doesn’t work, use a blowdryer for a few seconds to warm up the ink and get it flowing. 

Rollerball Pens

While rollerball pens are designed very similarly to ballpoint pens, ink is one of the differences between the pens. Since the ink is water-based, the ink tends to run out much faster. 

Your rollerball pen may have either run out of ink or some of the ink dried over the tip of the pen. 

You can remove the dried ink by scribbling on the sole of your shoe. 

Gel Pens

The gel pen’s ink is a mixture of both oil and water-based ink. The ink leans more toward the water-base and the ink can come in a wide variety of colors. 

Change in temperature is usually the reason for a gel pen’s ink to dry up. You can get the ink flowing again with either warm water or a blowdryer. 

Fountain Pens

Fountain pens are prone to becoming clogged with flecks in the ink. The main reason a fountain pen stops working is either the ink has dried or the nib is clogged. 

You can remove the ink cartridge and run warm water through the pen to remove the dried ink and small flecks. If for some reason running water doesn’t work, you can use a special pen cleaning solution that can remove the small flecks. 

Another thing to consider when a pen has stopped working is the paper. Some papers have a waxy buildup that pens refuse to write on. 

There could also be indents from writing on previous papers that do not allow the pen to write.
