Printer ink can permanently stain a carpet, making it look unsightly. However, spilling printer ink on a carpet does not have to be a major disaster. In fact, you can use household chemicals to remove--or at least minimise--the printer ink from the carpet easily.
Blot up as much liquid as you can using one of the towels. Pat the ink stain as you work. You should do this for 1 to 2 minutes.
Dampen another towel with rubbing alcohol. Use just enough to make it wet. Do not soak the towel with it. Blot the stain with the rubbing alcohol-dampened towel for 3 to 4 minutes.
Use hydrogen peroxide if the stain persists. Dampen another towel with enough hydrogen peroxide to moisten the towel. Pat down on the ink stain. This time, leave the towel on the stain overnight to remove the stain.
Ideally, you want to do this as soon as the stain occurs. The faster you respond to a printer ink stain, the more stain will come off the carpet.
Do not put hydrogen peroxide or alcohol directly on the carpet or the stain or you will further damage the carpet. Only use a towel that you have poured the chemicals on with the ink stain.
