Ink stains can be challenging to remove from paper, especially if you do not have the option of white correction liquids or erasable ink. These white correction products can also be impractical to use for your stain removal job, especially if your document is Manila or an off-white color. With a few products available for purchase in local retail stores, you can remove your blue ink stain on any type of document.

Step 1.

Purchase hydrochloric acid from the store or online. This product is available in salt or liquid form.

Step 2.

Put on a pair of gloves as a safety precaution, and leave them on during the entire process.

Step 3.

Dilute the hydrochloric acid with water. You can use warm tap water. Dilute the chemical with one part chemical to five parts of water.

Step 4.

Dip a cotton swab in the chemical and water solution. Keep a handful of swabs on hand depending on how large the stain is.

Step 5.

Rub the stain gently with the cotton swab, carefully to avoid damaging the document.

Step 6.

Allow the document to air-dry upon removing the stain.
