Here’s how to wash them properly, especially when using a product like “wetening” (which might be a typo or a specific term not commonly recognized; I assume you mean.

1. Sort the Clothes: Separate dark-colored clothes from lighter ones to prevent color bleeding. Washing darks with darks minimizes the risk of dye transfer.

2. Pre-Treat Stains: If there are stains on the clothes, treat them before washing. Follow the care label’s instructions or use a stain remover appropriate for dark fabrics.
3. choose Cold Water: When washing dark clothes, opt for cold water. Hot water can cause color fading, especially in dark fabrics.
4. Use a Mild Detergent:Use a gentle detergent designed for dark or colored fabrics. Harsh detergents can strip the color and affect the fabric’s integrity.
5. Add Wetening/Detergent: Add the appropriate amount of wetening/detergent to the washing machine. Follow the product’s instructions for the right dosage.
6. Load the Machine: Don’t overcrowd the washing machine. Leave enough space for the clothes to move freely and get thoroughly cleaned.
7. Choose the Right Cycle:Use a gentle or delicate cycle to minimize friction and stress on the fabrics.
8. Avoid Overusing Detergent:Using too much detergent can leave residues on dark clothes, affecting their appearance. Follow the recommended dosage on the detergent’s packaging.
9. Skip Fabric Softener:Fabric softeners can affect the color and texture of dark fabrics. It’s best to skip using fabric softener when washing dark clothes.
10. Fasten Zippers and Buttons:Zip up zippers and fasten buttons to prevent them from snagging on other clothes.
