How to wash a printed t-shirt — keep your DTG & DTF print sharp for 60+ washes
Printed cotton lasts surprisingly long when you treat it right. The single biggest killer of any print is mechanical abrasion from another piece of clothing in the same wash — not the temperature, not the detergent. Below are the rules our production team gives the studio's own staff for the apparel they wear daily.
The 30-second answer: wash inside-out at 30 °C with similar colours, no fabric softener, no bleach, tumble-dry on low or hang-dry, iron on the reverse only. That's it. Skip the rest of this page if you're in a hurry.

Our 60-wash longevity claim — what it actually means
Every batch we print is dropped into a domestic Bosch washing machine in our QC area for a 5-cycle simulated-life test (30 °C, mid-cycle, mixed cotton load). Inks must show no visible cracking, fading or loss of opacity after 5 cycles. We extrapolate to 60+ real-world washes assuming care-guide compliance — it's a real test, not marketing.
If your print cracks or peels within 60 washes and you've followed this page, send a photo to info@shirtaki.io — we reprint and ship free. Reprint policy →
Why DTG & DTF prints behave differently from screen-printed merch
Most cheap merch tees are plastisol screen-printed — a thick PVC ink layer sits on top of the cotton like a sticker. It feels rubbery, blocks the cotton from breathing, and cracks when over-stretched. We don't print like that.
We use two modern techniques:
- DTG (Direct-to-Garment). Water-based pigment is absorbed into the cotton fibres, like an inkjet onto fabric. The print becomes part of the shirt — soft hand-feel, full-colour photographic detail. Used on Custom Front Print, Custom Front + Back, all kids tees and the Dolce Banana Shirt.
- DTF (Direct-to-Film). Pigment is printed onto a film, then heat-pressed onto the garment with a flexible polymer adhesive. Sharper edges and stronger opacity on dark fabrics — we use it on hoodies, the Acid-Washed Heavy Oversize Tee and Oversize Tee Heavy when the design demands it.
Both are extremely durable when treated correctly. Both fail prematurely under one specific abuse: high-heat tumble-drying immediately after a hot wash. The fibres lose moisture too quickly, the ink-fibre bond contracts unevenly and microcracks form. Avoid that one habit and your print will outlast the cotton.
The five rules — long version
- Always wash inside-out. 80 % of cracking and fading is caused by abrasion against zippers, denim seams and rough synthetics. Inverting the garment puts the printed surface against the soft inside of itself.
- Cold to lukewarm — 30 °C max. Modern detergents are formulated to clean fully at 20–30 °C. Hot water (60 °C+) breaks down the cotton-pigment bond on DTG and softens DTF adhesives. There's no reason to wash printed cotton hot.
- Liquid detergent, mild dose, no bleach, no softener. Powder detergent leaves micro-abrasive residue on the print. Optical brighteners attack pigment dyes. Fabric softener coats fibres with silicone, dulling both the print and the cotton's hand-feel.
- Tumble-dry on low — or hang-dry. High heat is the single most common cause of premature print failure. If you must use a dryer, set it to delicate/low and pull garments while still slightly damp. Air-dry is best for 240–400 GSM heavy garments.
- Iron on the reverse, never on the print. If you absolutely must touch the front, place a clean cotton cloth between iron and print, no steam, low heat (max 110 °C / 1-dot setting).
What NOT to do — the killer list
- No dry-cleaning. Perchloroethylene and other solvents dissolve the polymer binders in DTF and strip pigment from DTG. Always machine-wash.
- No bleach. Including oxygen / oxy bleach. Even pre-soaking ruins the print colours within minutes.
- No tumble-dry on high. 60 °C+ dryer cycles are the #1 cause of warranty claims we see.
- No fabric softener. Coats the fibres, reduces print adhesion over time, traces left in fleece are nearly impossible to rinse out.
- No leaving wet, balled-up, in the machine. Pigment can lift slightly when wet; the print smudges if pressed against itself for hours.
- No washing brand-new dark print with brand-new white denim. Use common sense — first-wash dye bleed is real on any new garment.
- No starch sprays directly on the print. Starch dries hard and cracks the print on the next wear.
The first-wash protocol — do this once, get years of print life
Every cotton garment shrinks slightly on its first wash. Doing the first wash properly stabilises the fabric, sets the print and minimises future shrinkage:
- Wait at least 24 hours after delivery before washing. The DTF cure continues for ~24h post-pressing — washing immediately reduces longevity.
- Wash alone or with similar new colours. First-wash dye bleed happens on any cotton garment, not a print defect.
- Inside out, 30 °C, gentle/synthetic cycle, half the usual detergent dose.
- No softener, no bleach, no scent boosters.
- Hang-dry flat or on a wooden hanger. Skip the tumble-dryer entirely on the first cycle.
- Optionally: low-temperature iron on the reverse after fully dry. This stabilises the cotton and locks in the print's hand-feel.
Care matrix per fabric weight
Different garments tolerate different conditions. Here's exactly what each fabric we stock can handle:
| Fabric | Used on | Max wash | Dryer | Iron | First-wash shrink |
|---|---|---|---|---|---|
| 180 GSM lightweight cotton | Essential Tee, Dolce Banana, Hugge Tee | 30 °C, gentle | Low or air-dry | Reverse, 1-dot, no steam | 1–2 % |
| 200 GSM midweight cotton | Custom Front-Print, Front + Back, kids tees | 30 °C, gentle | Low | Reverse, 2-dot | <3 % |
| 240 GSM heavy / oversize cotton | Acid-Washed Oversize, Oversize Tee Heavy | 30 °C, gentle | Hang-dry preferred | Reverse, 2-dot, no steam on print | 2–4 % length |
| 280 GSM long-sleeve / sweat | Heavy Blend Crewneck | 30 °C, gentle | Hang-dry only | Reverse, 2-dot | 3–4 % |
| 400 GSM brushed-back hoodie fleece | Custom Hoodie, Hoodie F + B | 30 °C, gentle | Hang-dry mandatory | Reverse only, 2-dot, no print contact | 3–5 % |
| Quick-dry polyester (swim) | Swim shorts | 30 °C, rinse first if salt/chlorine | Air-dry only | Not required | 0 % |
Salt & chlorine on swim shorts: always rinse in fresh water within 24h of swimming. Salt crystals are abrasive; chlorine is a mild oxidiser that fades printed colours over months of pool use.
Stain removal without destroying the print
- Treat fast. Within 30 minutes, blot (don't rub) with cold water from the inside of the garment, pushing the stain back out the way it came in.
- Oil & food. A drop of clear dishwashing liquid worked into the fabric with fingers, left for 10 min, then cold-rinsed. Do not use stain bars containing bleach or oxy.
- Coffee, wine, tea. Cold soda water poured from the inside, then 30 °C wash. Avoid hot water — it sets tannins permanently into cotton.
- Sweat/yellowing on white tees. Pre-soak in cold water + 1 tbsp white vinegar for 30 min, never bleach. The print is fine; the cotton brightens.
- Ink, paint, lipstick. Don't try home remedies — they often make it worse. Cold-wash twice; if it remains, it's not coming out.
- Whatever you do — never apply heat (iron, dryer, hairdryer) to a stain before washing it out. Heat permanently bonds organic stains to cotton.
Ironing & steaming
- Always iron inside-out. The reverse of the garment is ironed; the print is never touched directly.
- Temperature: 1-dot (110 °C) for 180 GSM, 2-dot (150 °C) for 200–400 GSM cotton. Never 3-dot.
- No steam directly through the print. Steam loosens DTF adhesives if pulsed onto a small area.
- Steamer instead of iron: hold 10 cm away from the garment, never press. Works perfectly on hoodies and oversize tees.
- Pressing cloth: if you must press the front (e.g. removing a deep crease), place a clean white cotton cloth between iron and print. No exceptions.
Long-term storage & folding
- Fold, don't hang. Hangers stretch the shoulder of midweight cotton over months. Fold flat in a drawer or shelf.
- Print-side in. When folding, keep the print on the inside of the fold so it isn't pressed against another garment's hardware.
- Avoid plastic bags. Cotton needs to breathe. Long-term storage in airtight plastic can yellow whites and cause musty smells.
- Hoodies on broad wooden hangers. Acceptable for short-term wardrobe storage thanks to the heavy fleece. Use a 5+ cm shoulder to spread the weight.
- Cool, dry, dark. UV light fades pigment over months. Never store printed cotton on a sunny shelf.
Troubleshooting
- Print feels stiff after first wash. Normal — water reactivates the binder briefly. Soft-hand returns by wash 2.
- Tiny white dots on the print. Detergent residue. Re-wash with half the detergent, no softener.
- Print edges look slightly cracked. Almost always heat damage from a hot dryer. We reprint if within 60 washes & care-compliant.
- Garment smells of detergent after drying. You're using too much or skipping the rinse cycle. Run an extra rinse, halve the dose.
- Colour faded on one side. Storage UV exposure. Move to a dark wardrobe.
- Hoodie cuffs/hem stretched out. Tumble-dry on low for 5 min to re-tension the rib knit.
Care FAQ
Can I machine-wash a printed Shirtaki garment?
Yes — every product we sell is machine-washable at 30 °C on a gentle cycle, inside-out. Hand-washing is fine but not required.
Why 30 °C and not 40 or 60?
30 °C kills body-soil and most bacteria with modern enzymatic detergents while preserving the cotton-pigment bond. 40 °C is acceptable but shortens life by ~15 %. 60 °C+ visibly degrades any printed garment within 10–15 cycles.
Can I tumble-dry a printed t-shirt or hoodie?
Tees: yes on low (delicate/synthetic setting, <50 °C). Hoodies and 280–400 GSM heavy garments: hang-dry only — high heat causes hoodie cuffs to twist and the print's polymer adhesive to age prematurely.
Can I iron over the print?
No, never directly. Always iron the reverse side at 2-dot (≤150 °C) without steam. If the front needs ironing, use a clean cotton pressing cloth between iron and print.
Will the print fade over time?
If care-guide-compliant, expect virtually no fading for the first 60–80 washes, gradual softening of contrast after that, and a vintage-look fade after 150+ washes. The cotton itself usually fails before the print does.
My print cracked — is it covered?
Yes, if within 60 washes and you've followed this care guide we reprint and ship free. Send a photo to info@shirtaki.io. See returns & reprints.
Is it safe to use a steamer on the print?
Yes — held 10 cm away, no contact. Steaming is preferable to ironing for hoodies and oversize tees.
Can I bleach or oxy-soak whites?
No. Both bleach and oxygen bleach destroy DTG and DTF inks. Use cold water + a tablespoon of white vinegar for natural brightening.
Does fabric softener really matter?
Yes — silicone-based softeners coat the fibres, reducing print adhesion long-term and dulling cotton's natural feel. They also cause fleece on hoodies to mat. Skip them entirely for printed apparel.
How do I wash a printed kids' tee?
Same rules — 30 °C, inside-out, no softener. Kids tees are 200 GSM ringspun cotton; allow ~4 % first-wash shrinkage. Pre-soak grass and food stains cold immediately.
Can I wash printed swim shorts in the same load as a tee?
Yes, but rinse the swim shorts in cold fresh water first to remove salt or chlorine. Polyester and printed cotton wash compatibly at 30 °C gentle.
My white tee turned slightly yellow at the armpits — print's still fine. What now?
That's antiperspirant + cotton oxidation, not a print issue. Pre-soak in cold water + 1 tbsp white vinegar for 30 min, then normal 30 °C wash. Do not bleach.
