But with the right approach and a little patience, you can often lift the stain without damaging the delicate wool.
This guide focuses on set-in grease on a wool blazer. We'll cover what to do first, step-by-step removal methods, what to avoid, and how to tell if the stain is coming out or if you should stop.

Why Wool Needs Special Care
Wool is a natural protein fiber that is more delicate than cotton or polyester. It can shrink, felt, or become misshapen if exposed to heat, harsh agitation, or strong chemicals. That's why you need to use gentle methods and avoid hot water, vigorous scrubbing, and bleach.
What to Do First
If the grease stain is already set in, don't rub it. Rubbing can push the grease deeper into the fibers and spread the stain. Instead, start by gently scraping off any excess grease with a dull knife or the edge of a spoon. Then, place the blazer on a flat surface and sprinkle a generous amount of baking soda over the stain. Let it sit for at least 30 minutes to absorb some of the oil.
