1. Use detergent for colored laundry and use the correct dosage
We recommend using detergent for colored laundry for your white shirts, even though it may sound illogical.
This is because there are often different types of bleach in White detergent, which can react with the finish the shirt has received to be as white as snow. In the worst case, the shirt can turn yellow.
Avoid various aggressive stain removers. Overdosing does not make clothes cleaner. It increases the enzyme content and can over time contribute to reducing the shirt's lifespan, and in the worst case, also discolor the clothes.
2. Skip the fabric softeners and wash at low spin speeds
We recommend washing at low spin speeds (400-600 rpm) as this gives the most wrinkle-free result.
Fabric softeners do not make clothes cleaner and have no measurable effect on softness. Fabric softeners also contain chemicals that burden the environment when they end up in wastewater (source: Environmental Protection Agency).
Additionally, we have found that certain white textiles, depending on the finish, can react differently to fabric softeners by becoming discolored.
3. Hang your wet shirts on hangers after washing
To achieve the most wrinkle-free result, the most important thing is to wash at low spin speeds and even more importantly, to hang the shirt on a hanger immediately after washing. This way, you get incredibly close to wrinkle-free.
We develop our fabric in collaboration with our Swiss fabric partner, specifically to create as wrinkle-free a shirt as possible. A 100% cotton shirt cannot be 100% wrinkle-free. Yet. But we are working on making shirts as wrinkle-free as possible, without the use of harmful chemicals and synthetic materials, mind you.
And if an accident happens...
If your shirt has still become a bit yellowish, you can find a guide on how to get it white again. In our experience, soda is most effective, while citric acid works best for small accidents.
