Screen printing at home has become increasingly popular for custom T-shirts and fabric projects. The ink used in screen printing falls into two main categories: water-based ink (the most common for home hobby use) and plastisol (a PVC-based ink used in commercial printing). These two types behave very differently on carpet and require different cleaning approaches. Using the wrong method — particularly trying to rinse plastisol with water — wastes valuable time without helping.
Water-based vs plastisol screen printing ink
| Property | Water-based ink | Plastisol ink |
|---|---|---|
| Carrier | Water | PVC resin in plasticiser oil |
| Air dries? | Yes — becomes harder to clean quickly | No — remains workable until heat cured |
| Clean up with | Cold water + dish soap (wet); harder when dry | Mineral spirits or screen printing ink remover |
| Heat cure needed? | Yes (160°C+) | Yes (160°C+) |
| Common home brands | Jacquard, Speedball water-based | Speedball plastisol, Ryonet |
Cleaning water-based screen printing ink
Water-based screen printing ink behaves similarly to thick acrylic paint on carpet. It is water-soluble when wet and becomes progressively harder to remove as it dries. The key is to act immediately.
- Scrape up excess ink with a blunt knife or spoon, working from the outside of the spill inward.
- Blot remaining ink with a dry cloth to absorb as much as possible.
- Apply cold water to the stained area and blot repeatedly. The water-based ink should begin to dilute and lift.
- Apply dish soap solution (1 teaspoon dish soap per cup of cold water) and blot. Work the soap gently into the ink residue.
- Rinse thoroughly with cold water blotting until no more colour transfers and all soap is removed.
- Allow to air-dry. If ink has partially dried before you reached it, apply cold water and allow to soak for 5 minutes to re-hydrate before blotting.
Cleaning plastisol screen printing ink
Plastisol ink does not air dry — it remains as a pliable, oil-based paste until heat cured at around 160°C. This means a plastisol spill on carpet remains workable for much longer than water-based ink. Do not apply water to plastisol — it does not help. Instead, scrape up as much of the paste as possible, then apply mineral spirits (odourless mineral turpentine) or a dedicated screen printing ink remover to a cloth and blot the residue. After lifting the plastisol, apply dish soap solution to remove the mineral spirits from the carpet, then rinse with cold water and blot dry.
Do not use heat to help clean screen printing ink
Both water-based and plastisol screen printing inks cure permanently at high temperatures. A clothes dryer, heat gun, or iron applied to spilled ink will cure it into the carpet permanently. Always use cold water for water-based ink and room-temperature mineral spirits for plastisol.
Dried or heat-cured ink in carpet
Dried water-based screen printing ink can be partially re-hydrated with cold water and treated with dish soap, though it becomes significantly harder to remove as it sets. Plastisol that has been inadvertently heat-cured (for example, if a hot object was placed on the spill) behaves like a flexible plastic film and cannot be dissolved — mechanical removal is the only option. For large or set ink spills, a professional carpet cleaner with appropriate extraction equipment can achieve better results than extended DIY treatment.
Screen printing ink on carpet and not fully lifting?
For set or partially-cured screen printing ink, a local specialist can assess whether professional extraction or treatment is appropriate for your carpet type and ink type.

Frequently asked
How do I know if my screen printing ink is water-based or plastisol?
The easiest check is the cleanup instructions on the product label. Water-based inks state "clean up with water" or "wash with soap and water." Plastisol inks state "clean up with mineral spirits" or "use ink remover." If you no longer have the label, water-based ink is thinner and more fluid, dries to a matte or satin film on fabric, and washes out of screens with water. Plastisol is thick, stays pliable when cool, has a greasy or oily feel, and does not wash out of screens with water alone. Plastisol also does not have an obvious "drying" smell — it just stays wet until heated.
I spilled black screen printing ink on a light cream carpet. It is water-based. Will it come fully out?
Black water-based screen printing ink on light carpet treated immediately has a good chance of near-full removal. The black pigment (typically carbon black) is a very fine particle that can embed in carpet fibre, but with thorough cold water flushing and repeated dish soap blotting, most of it can be removed. Any residual grey tinge after the main cleaning is from fine carbon particles deep in the fibre — a second dish soap treatment round after the carpet has dried and the extent of remaining staining is clear can progressively reduce it. On very light carpet, a small grey tinge may remain if the ink was concentrated or contact time was long.
Plastisol ink from the squeegee dripped onto the carpet hours ago and I just noticed it. Is it still treatable?
Yes — plastisol does not air cure, so even hours-old plastisol on carpet is still in its uncured, workable state. It will feel like a thick, greasy paste in the carpet pile. Scrape up the bulk with a blunt tool first, removing as much volume as possible. Then apply odourless mineral spirits or screen printing ink remover to a cloth and blot from the outside in. The plastisol should dissolve and transfer to the cloth with repeated blotting. Follow with dish soap to remove the mineral spirit residue, then rinse with cold water. Plastisol left on carpet for days or weeks becomes harder to scrape but remains uncured — the same mineral spirits approach still applies.
