Vinyl flooring is durable and easy to clean, but every family has its mishaps; sooner or later you're going to encounter a stubborn stain on your floor. A typical example is ink from a pen. Whether a pen has dropped and leaked or an errant toddler has unleashed his artistic talent in the wrong place, you can rest assured that pen ink won't destroy your vinyl flooring.
Fold a paper towel into quarters.
Pour 1 tsp water and 2 drops dish detergent onto the paper towel.
Rub the area of pen ink briskly, using a back-and-forth motion and refolding the paper towel as the ink is absorbed.
Repeat the process, substituting isopropyl alcohol for dish detergent until all of the stain has disappeared.
Remove all traces by cleaning the area with a vinyl floor cleaner that the flooring manufacturer recommends.
Stubborn stains may require treatment with white spirit.
