To wash sublimation shirts, turn them inside out, machine wash in cold water with a mild detergent, skip bleach and fabric softener, and tumble dry on low or hang to dry. That routine, which sublimation paper sellers and Cricut both publish, protects the polyester and keeps colors bright. On 100% polyester, a sublimated print doesn't crack or peel, so care is mostly about keeping the fabric itself in good shape.
Below are the steps, the reasons behind them, what changes on blends and cotton, and a care card you can copy for customers.
The washing routine, step by step
- Turn the shirt inside out. It reduces friction on the printed side during washing.
- Use cold water. Hot water is harder on polyester and on spray or HTV prints.
- Choose a mild detergent. Avoid bleach and "bleach alternative" detergents.
- Skip fabric softener. Cricut's care instructions for Infusible Ink also rule out dryer sheets.
- Wash with similar colors and lighter garments; avoid heavy, abrasive items like jeans with rivets.
- Dry on low or hang to dry. Line drying is the gentlest.
- Iron inside out on low if you need to, never directly on the design at high heat.
| Do | Don't |
|---|---|
| Wash inside out | Use bleach or bleach-alternative detergents |
| Use cold water | Use hot water |
| Use mild detergent | Use fabric softener or dryer sheets |
| Tumble dry low or line dry | Tumble dry on high heat |
| Iron inside out, low setting | Iron directly on the print at high heat |
| Store folded, away from direct sun | Leave in a hot car or bright window |
Where these rules come from
- Sublimation paper instructions from Dharma Trading tell you to turn the garment inside out, wash in cold water with a mild detergent, and not use bleach or bleach-alternative detergents.
- Cricut's Infusible Ink instructions, a sublimation-based system, say to machine wash inside out in cold water with mild detergent, tumble dry low or line dry, and not use fabric softener, dryer sheets or bleach.
- Printful, a large print-on-demand company, recommends washing printed shirts inside out to prevent friction and abrasion.
The guidance is consistent across sources: cool water, gentle products, low heat.
Why sublimation prints last on polyester
Sublimation dye turns into a gas in the press and bonds inside polyester fibers. Nothing sits on top of the fabric, so there's no film to crack, peel or flake, and the print feels like the shirt. That's why sublimation on 100% polyester is described as permanent.
What wears a sublimated shirt out is mostly what wears any polyester shirt out: abrasion, high heat and sunlight. Pilling, shine from a hot iron and fading in strong sun affect the fabric and the color together.
The washing routine can only protect what the shirt allows, so the blank matters too: the higher the polyester share, the brighter and longer-lasting the print.
How long does sublimation last on shirts?
| Shirt or method | What to expect |
|---|---|
| 100% polyester (or 90–95% with spandex) | Permanent with normal care; the print lasts as long as the fabric |
| 50/50 and other blends | Only the polyester holds dye; the print looks softer and fades more with washing |
| Cotton with a sublimation spray | Depends on the spray; follow its wash instructions and waiting time |
| Sublimation on HTV or sublimation HTV | Depends on the vinyl; HTV care is usually inside out, cool wash, low dry |
| Sawgrass VersiFlex on light cotton | Sawgrass cites up to 30 washes with cold wash and air dry |
| Cricut Infusible Ink on polyester | Cricut says it never flakes, peels, wrinkles or cracks |
If you sell shirts, the blank matters more than the washing routine. Our best shirts for sublimation guide explains which fabrics hold color best.
Polyester blends
On a 50/50 or triblend shirt, only the polyester share takes the dye. The design starts softer and keeps fading a little with each wash as the cotton fibers wear. Wash blends exactly as above, and tell customers to expect a vintage look rather than a bright, fixed print.
Sublimation on cotton (sprays, HTV and other methods)
When sublimation is done on cotton, the dye isn't in polyester fibers; it's held by a coating, spray or vinyl. These need more care:
- Sprays: follow the spray maker. HTVRONT's cotton guide, for example, says to wait 24 hours before the first wash. Expect more fading than on polyester; our sublimation spray for cotton guide covers the options.
- Sublimation on HTV: the vinyl is the weak point. Wash inside out in cool water, and avoid high dryer heat that can lift edges. We compare HTV methods in sublimation vs heat transfer vinyl.
- Infusible Ink and VersiFlex: follow Cricut's and Sawgrass's care instructions above; see sublimation vs Infusible Ink for how the two compare.
Ironing and heat
Polyester doesn't like a hot iron. It can shine, glaze or melt, and heat close to sublimation temperatures can make dye move again, softening fine detail. To iron a sublimated shirt:
- Turn it inside out.
- Use the low or synthetic setting.
- Put a pressing cloth between the iron and the design if you must press the printed side.
- Keep the iron moving.
The same applies to dryers: low heat is fine; high heat over many cycles shortens the life of the fabric.
Stains and spot cleaning
Treat stains as you would on any polyester shirt, with a mild stain remover tested on an inside seam first. Avoid chlorine bleach and harsh solvents on the printed area. Don't scrub the design with a brush; dab and rinse.
Washing other sublimated items
The same rules carry over to other polyester goods:
- Blankets and throws: wash on a gentle cycle in cold water, inside out if they have a printed side, and dry on low. Large items need room in the drum to avoid abrasion.
- Pillow covers and tote bags: remove inserts, turn inside out where possible, and wash cold. Air drying keeps the shape.
- Hats with sublimated fronts: spot clean or hand wash; a machine can crush foam fronts and brims.
- Mugs, tumblers and glass: these are coated hard goods, not fabric. Follow the blank maker's care; many sellers recommend hand-washing to keep the coating and print looking new.
A care card you can give customers
If you sell sublimated shirts, a short care card cuts complaints. Here's a version you can adapt:
Caring for your sublimated shirt Wash inside out in cold water with mild detergent. No bleach, fabric softener or dryer sheets. Tumble dry low or hang to dry. Iron inside out on low. Do not iron directly on the design.
For shirts printed on cotton with a spray or HTV, add the spray or vinyl maker's waiting time and care notes.
Common mistakes
- Washing right-side out with heavy items. Friction pills polyester and dulls the print area.
- Using hot water and high dryer heat. Hard on polyester and on any spray or HTV.
- Fabric softener on performance polyester. Cricut's Infusible Ink care rules it out, and it can leave residue on technical fabrics.
- Ironing directly on the design. Heat can shine the fabric and soften the print.
- Blaming washing for a weak print. If colors faded after one wash, the cause is usually the blend, too little press time or temperature, or a spray, not the washing machine. Our guide to how to sublimate a shirt covers pressing settings.
FAQ
How do you wash sublimation shirts?
Turn the shirt inside out and machine wash in cold water with a mild detergent. Skip bleach, bleach-alternative detergents, fabric softener and dryer sheets. Tumble dry on low or hang to dry. That's the routine sublimation paper sellers and Cricut give for sublimated and Infusible Ink garments.
How long does sublimation last on shirts?
On 100% polyester, sublimation is permanent: the dye is inside the fibers, so it doesn't crack or peel and lasts as long as the shirt with normal care. On polyester-cotton blends, only the polyester holds the dye, so the print fades more with washing. On cotton treated with sprays or sublimated on HTV, durability depends on that product.
Can you put sublimation shirts in the dryer?
Yes, on low heat. Cricut's care instructions for Infusible Ink, which is sublimation-based, say to tumble dry low or line dry. High dryer heat is harder on polyester and on prints made with sprays or HTV, so line drying is the safest choice.
Can you iron a sublimation shirt?
Yes, carefully. Iron the shirt inside out on the low synthetic setting, or use a pressing cloth, and don't park a hot iron on the design. Heat near sublimation temperatures can make dye move again, and polyester can shine or melt under a hot iron.
How long should you wait to wash a sublimation shirt?
On 100% polyester, the dye is set once the shirt cools, so you can wash it the same day. For sublimation on cotton with a spray, follow the spray maker; HTVRONT's cotton guide says to wait 24 hours before washing.
The bottom line
Cold water, inside out, no bleach or softener, and low or no dryer heat: that's all a sublimated polyester shirt needs. Put the effort into choosing high-polyester blanks and pressing them correctly, and the print will last as long as the shirt.
