Orange stains on white textiles, causes and rescue
Short answer: Orange stains on white textiles are usually rust coming from water, metal or the washing machine. They are easiest to remove while fresh, and you should not dry the item until the stain is gone, because heat can make it set in the fibres.
Why the fabric turns orange
Rust forms when iron reacts with water and oxygen, and small particles can settle in the fibres and leave an orange or brownish stain. On white textiles it shows very clearly, and it can hit both clothes and bedding without you having done anything wrong in the wash.
Typical sources around the home
The most common sources are pipes with rusty water, metal parts such as zips, hooks and bra wires, and a worn drum in the washing machine. It affects clothes and bamboo bedding alike, so start by finding the cause before you wash again, or the stains will simply come back.
Act quickly, before it dries
A fresh stain is much easier to remove than one that has dried in and been through several washes. Rinse the spot in cold water so that as much as possible loosens, and do not put the item in the dryer or on a radiator until you have seen that the stain is completely gone.
What you should avoid
Do not use chlorine bleach on rust stains, because it can make them set or look darker. Also avoid rubbing hard, since that wears the fibres, and do not wash hot until you have tried a mild method first and seen how the fabric reacts.
Gentle methods to try
On white textiles a rust remover made for fabric, or a mild acid such as citric acid, can often help if you follow the instructions and rinse thoroughly afterwards. Always test on a hidden spot first, read the care label and remember that acid is not suitable for every fabric or colour.
When the fabric is bamboo viscose
Viscose from bamboo can be more delicate when wet, so be gentle and avoid long soaks in strong products. Start with the mildest method, check the label and only move on to something stronger if the stain does not give way, and do it step by step.
How to stop it happening again
Let the water run until it is clear before you start the wash, and check pockets and metal parts on the clothes. Close zips and hooks, and if the machine drum is rusty or damaged it should be looked at, so that it does not ruin more clothes than necessary.
Looking after light clothes afterwards
Wash whites on their own with a mild detergent, so that stains do not hide in mixed loads. If you want something new in light colours anyway, you can look at Bamboo Basics and a bamboo dressing gown for men and take care of them from the first wash.
Frequently asked questions
What are orange stains on white textiles?
They are usually rust from water pipes, metal parts or a worn washing machine drum, which settles in the fibres and shows as an orange or brownish stain, especially on white clothes.
Can I use chlorine on rust stains?
It is not recommended, since chlorine can make rust stains set and turn darker. Use a rust remover made for fabric according to its instructions instead, and always test on a hidden spot first.
Should I dry the item before the stain is gone?
No, heat from a dryer or radiator can fix the stain, so check while the item is still wet that it is completely gone, and repeat the treatment if needed.
