Ketchup on Wool
Ketchup combines tomato pigments with sugar and vinegar. The longer it sits, the more it stains.
checklistTreatment Steps
Critical Warning
Never use hot water or agitation on wool — both cause irreversible felting and shrinkage. Use cool water and the gentlest possible motion. Avoid regular detergents, bleach, and enzyme cleaners — they break down wool's protein structure. Never tumble dry.
helpFrequently Asked Questions
How quickly should I treat a ketchup stain on wool?
expand_more
Ketchup combines tomato pigments with sugar and vinegar. The longer it sits, the more it stains. As a rule, fresh stains lift much more easily than dried ones — try to treat within the first hour for the best results.
Will hot water set ketchup stains on wool?
expand_more
Yes — hot water can lock tannin stains like ketchup into the fibres. Cool water is much safer until the colour is fully lifted.
Can I machine-wash wool after treating a ketchup stain?
expand_more
Yes — once the stain is fully lifted, machine wash according to the care label. Never run wool through the dryer if the stain is still visible: heat will set it permanently. Air dry and inspect the area first.
What if the ketchup stain comes back after drying?
expand_more
Stains that reappear are usually residue or oil that wicked back up as the fabric dried. Repeat the treatment from step one, and avoid heat-drying until the stain is completely gone. Multiple gentle passes work better than one aggressive treatment.
Can I use bleach to remove ketchup from wool?
expand_more
Only if the care label specifically allows it — and never on coloured wool. Bleach can weaken fibres and create permanent white patches. Oxygen bleach (non-chlorine) is a gentler option when bleaching is needed.
