How to Clean a Biro Off a Leather Chair 
If you have a biro stain on your leather chair, there are a number of different ways to remove it. The first step is to use washing-up liquid to rub at the stain from the outside inwards. Repeat this process as often as necessary until the stain has disappeared. Another effective method is to use white vinegar. You can dilute the vinegar with water and apply it to the stain.
White vinegar
A great way to get rid of a biro stain on your leather chair is with a little white vinegar. If you’re not sure how to use the vinegar, you can also use a nail polish remover. Just be sure to dab off any excess ink with a paper towel before applying the cleaning solution. You should always test your cleaning solution on a hidden area first before applying it to your leather chair. If you can, use the underside of a cushion as a test spot to see if the cleaning solution will be effective. This way, you’ll know whether or not the chemicals will ruin your leather.
If you’re using rubbing alcohol to clean a biro stain, you should try a patch test first. If the stain is stubborn, you may need to repeat the process. You can also use a rehydrating conditioner after the rubbing alcohol has worked on the stain.
COLOURLOCK Ballpoint Pen Remover
If you’re looking for a quick and easy way to remove a biro or ballpoint pen mark from your leather chair, then you’ve come to the right place. This product works by softening ink, dissolving the stain, and cleaning the pen tip. It also works on both sides of the ink stain, so you don’t need to use too much pressure to remove the stain.
The biro is an invaluable tool, but it can easily stain your leather chair or leather surface. To avoid damaging the rest of the leather, you should try to remove the stain as soon as possible. When you choose a product to use, make sure to test it first to ensure that it won’t damage the rest of the stain. You can also try using white vinegar or washing up liquid in place of commercial products.
Another effective way of removing the ink from leather is by applying a solution of one part white vinegar and one part water. This solution can be kept in a bowl and applied to the stain with a clean cloth whenever needed. This solution will remove the stain from the leather without any issues. However, you should always test the product on a hidden spot before applying it on the whole of your leather chair.
rubbing alcohol
If you want to clean a biro stain from a leather chair, you can use rubbing alcohol. This substance can be effective at cleaning ink and postmortem fluids, but you have to make sure to wipe it off immediately to avoid damaging the leather. Using a cotton swab or folded white paper towel will help you soak up the alcohol, remove the ink, and dry the leather. Alcohol can eat away at the leather over time.
You can also use washing up liquid or a commercial leather cleaner. These products are more effective than plain alcohol and can help extend the life of your leather chair. Some even come with instructions for how to use them to remove stains. If you’re not confident with your ability to remove biro, it’s a good idea to call a professional to get the stain removed.
Before using any cleaning product, do a spot test on a small hidden part of the chair to make sure it doesn’t damage it. A good place to do this is the underside of a cushion. This way, you can see whether it is safe to use and if it will damage the leather or not.
Saddle soap
Saddle soap is designed to clean leather saddles. It is a blend of gentle soaps and emollients to restore moisture to leather. Regular use will help the leather stay looking good and last for a long time. You can purchase saddle soap online or from a leather care store. Some brands include Carr & Day & Martin.
For a less aggressive way to remove a biro stain, you can use washing-up liquid. Then, gently rub at the stain, starting from the outer edge and moving inwards. Repeat this until the stain is removed. A mixture of water and white vinegar can also work.
Before trying any new cleaning method on a leather chair, you should first do a patch test first. To ensure the product is safe for your furniture, dab a small amount of rubbing alcohol onto the spot. If the stain is stubborn, you might have to repeat the process a couple of times. If you are still not satisfied with the result, you can apply a rehydrating conditioner.
