Washing Tips to Keep Dark Clothes From Fading

Even the best detergent for black clothes won’t save your t-shirts if you’re not washing them properly. Here’s how to make your dark t-shirts last longer:

Turn Clothes Inside Out – This protects the visible fabric surface from friction and lint during washing.

Use Cold Water – Heat can break down dyes and fade color faster. Always use cold water when washing dark clothes.

Choose the Right Wash Settings – Go for a gentle or delicate cycle. Avoid heavy-duty cycles that are too rough on fabric.

Wash with Like Colors – Don’t mix darks with lights. Washing black clothes with other dark items reduces lint transfer and dye bleeding.

Air Dry When Possible – Heat from the dryer fades color quickly. If you can, hang your dark t-shirts to dry or use a low-heat setting.

If you’re buying wholesale blank t-shirts or stocking up on affordable t-shirts in dark colors, proper care is even more important. Bulk-purchased shirts often use reactive dyes that can fade faster with poor washing habits. Using the best detergent for black clothes and following our care tips helps you get more wear—and more value—from every shirt.
