Can I use hot water to remove set-in grease from cotton?

No, avoid hot water before treatment. Heat can set the grease further into the fibers. Use warm or cold water for rinsing and washing.

How long should I let baking soda sit on a grease stain?

Let the baking soda and dish soap sit for 15-30 minutes. For very set-in stains, you can leave it for up to an hour to allow the mixture to break down the grease.

What if the grease stain doesn't come out after washing?

If the stain remains after washing, do not dry the apron. Repeat the treatment process before washing again. If it persists after two or three attempts, it may be permanent.

Part 1: Material and risk

Set-in grease on a cotton apron is a common kitchen problem. Whether it's from cooking oil splatters or a buttery mishap, the stain can look dark and oily. But you don't have to toss the apron. With dish soap and baking soda, you can lift the grease without damaging the cotton. This guide walks you through the steps for set-in stains, with cotton-specific precautions.

Why Set-In Grease Is Stubborn

Grease is oily, and oil repels water. When it dries into cotton fibers, it can be hard to remove with regular detergent alone. The key is to break down the oil with a degreasing agent, then absorb it with a powder like baking soda. Acting quickly is best, but even set-in stains can be treated successfully.
