If you can't get all the paint out then that's a good time to think about replacing it.
If you are looking for more details, kindly visit our website.
The problems you might get are some paint flecks from the old paint coming off onto the newly painted surface - which will ruin the finish, or some of the old colour leaking into the new.
I wouldn't worry about the colour of the roller material itself and it is a good sign that you can still get a nap on the roller.

Because of the structure of the fabric, our 10mm Dacron rollers perform best with acrylic paints and are not suitable for oil-based paints.
If you’re priming your brand-new plasterboard walls or repainting either darker or lighter, our Dacron is the best pick to achieve optimal coverage and a professional-looking finish. Learn more about Dacron vs. microfibre here.
Our Dacron paint roller sleeve will give you superb coverage while our Microfibre paint roller sleeve will leave a smooth finish.
