Ketchup on Wood
Ketchup combines tomato pigments with sugar and vinegar. The longer it sits, the more it stains.

Critical Warning
Water is the enemy of wood — excess moisture causes warping, swelling, and permanent staining of the grain. Work quickly and dry immediately. Never use bleach, ammonia, or abrasive cleaners on wood — they strip the finish and damage the grain.
helpFrequently Asked Questions
How quickly should I treat a ketchup stain on wood?
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 wood?
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 wood after treating a ketchup stain?
expand_more
Yes — once the stain is fully lifted, machine wash according to the care label. Never run wood 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 wood?
expand_more
Only if the care label specifically allows it — and never on coloured wood. Bleach can weaken fibres and create permanent white patches. Oxygen bleach (non-chlorine) is a gentler option when bleaching is needed.
