How to remove a mayonnaise stain:
Greasy classic? No chance with this tutorial

A story from life

"I indulged in a sandwich at a party. Before I knew it, mayonnaise had slipped down the sleeve of my new blouse. I wiped it off with a paper napkin and threw it in the washing machine. And the mistake - there was a greasy grey stain after washing. Only a combination of soda, lemon and blotting paper did the trick."

- Lucka, EcoHaus customer

Why mayonnaise is one of the tough stains

Mayonnaise is a greasy emulsion made up of eggs, oil, mustard and acids (vinegar/lemon). That means: ✅ fat, ✅ protein, ✅ dyes, ✅ acids - four different ingredients that need more than just water and detergent. If the mayonnaise is washed off right away without pre-treatment, the fat can get deep into the fibers and leave a gray or yellow trace.

How to stain mayonnaise step by step

What helps:

• Cold water
• Baking soda
• Citric acid or lemon juice
• White vinegar 10%
• EcoHaus Washing Papers
• Sodium percarbonate - ideal for white or light fabrics

Procedure:

1. Gently scrape off the mayonnaise residue with a spoon - do not rub into the fabric.
2. Rinse the stain with cold water on the reverse side.
3. Apply a paste of baking soda and lemon juice (or citric acid and water).
   Why it works: The baking soda draws out the fat and protein, the acid breaks down the remaining emulsion.
4. Leave on for at least 15 minutes, gently blend.
5. Wash with EcoHaus washing papers - at 30-40°C.
6. For light-coloured laundry, add sodium percarbonate.
   Why it works: Active oxygen removes pigment and brightens the fibre.

What to watch out for

• Don't use hot water. The grease will be "baked" into the fibers by the heat.
• Do not wash without pre-treatment. The stain will remain and oxidize to grey.
• Do not try aggressive bleaches. Chemical deterioration of the fabric may occur, but not removal of the grease.

➙ Tip from Grandma Petra

For mayonnaise, my grandmother always said, "Fat first, then wash." Apply the paste of soda and lemon as soon as possible, even more than once. Usually one cycle of washing with percarbonate is all it takes to save the laundry.

➙ Tip from Vlaďka - the cleaning lady

Mayonnaise stain? A mild solution of vinegar and soda is best, leave for 10 minutes, then wash and rinse. If it doesn't work the first time, add percarbonate and put in the sun.
