Wash paint rollers before use to remove loose fibres and residue
It is important to wash your paint rollers before use to ensure that there is no loose fibre residue on your roller. This will also help you achieve a flawless finish.
Firstly, hold the roller upright over the paint can and use a metal scraper to remove excess paint. Be careful not to use too much force, as you may damage the roller. If you are taking a break and the job isn't finished, you can skip the cleaning process for now. Simply wrap your roller in plastic wrap and put it in the refrigerator.
If you are using water-based paint, rinse the roller sleeve in cold water first, removing as much of the remaining paint as possible. Then, add a few drops of washing-up liquid and massage the roller sleeve to work the paint out. Rinse the roller in clean water and repeat the process until no more paint comes out.
If you are using oil-based paint, you will need to use a solvent such as mineral spirits or a specialist brush cleaner to clean the roller. Place the roller cover in a small container of paint thinner and use a putty knife or the curved edge of a 5-in-1 tool to scrape off any excess paint.
Once you have removed the paint, rinse the roller thoroughly with warm water and shake off any excess moisture. Stand the roller cover on its end to dry. You can also use a spinner to dry the roller in a 5-gallon bucket. If it will be a long time before you reuse your roller, wrap the roller sleeve in cling film or a plastic bag to prevent dust or dirt from getting into the fibres.

Rinse with cold water first to remove excess paint
Rinsing a roller with cold water is an important first step to remove excess paint. This step is vital as it preps the roller for even coverage and a flawless finish. It is also a good way to remove any loose fibres or other residues.
To do this, you can use a putty knife or a 5-in-1 tool to scrape off the excess paint. Then, place the roller under a tap or fill a spray bottle with water and spin the roller, spraying it until it is noticeably wet. If you are using a garden hose, leave the roller on the frame and spray the roller to make the water spin the roller rapidly.
Once you have rinsed the roller with cold water, you can then use warm water and a small amount of dish soap to clean the roller further.
If you are using oil-based paint, you will need to use a solvent such as mineral spirits to remove the excess paint.

Use warm water and dish soap for the next stage of cleaning
Properly cleaning and storing your paint roller will ensure that it lasts longer and delivers smooth, streak-free results. It is also more economical to reuse your roller than to discard it after each use.
After scraping off any excess paint with a putty knife, the next step is to rinse the roller with warm water and a small amount of dish soap. Kevin O'Donnell, a Crown technical demonstrator, recommends first rinsing the roller with cold water to remove as much remaining paint as possible. He cautions against using hot water too soon, as this can cause certain paints to congeal or dry within the sleeve, making cleaning more difficult.
Once you have rinsed off the excess paint with cold water, you can then move on to cleaning the roller with warm water and dish soap. Fill a bucket with warm water and add a few drops of dishwashing liquid. You can then use your hands to work the soapy water through the fibres of the roller. This should take around five to ten minutes.
After you have finished cleaning the roller with warm water and dish soap, gently squeeze out any excess moisture. Set the roller upright on its end or hang it on a pants hanger to air dry. Avoid placing the roller on its side to dry, as this will flatten the fibres.

Clean the roller frame and paint tray, too
It is important to clean your roller frame and paint tray at the end of each painting session. The clean-up is much easier and more successful when the paint is still wet. Wear rubber gloves to protect your hands and pull the roller from its frame. Place the roller in a bucket of warm water with a few drops of dishwashing liquid. Use your hands to massage the paint out of the roller fibres, ensuring you clean every surface. Then, use a stream of fresh water or a new bucket of water to rinse the roller. This may take several minutes. Shake off any excess water and leave it to air dry—but never place the roller on its side, as this will flatten the fibres.
To clean the roller frame and paint tray, place some warm water and a few drops of dishwashing liquid in a bucket. Use an old rag or a stiff-bristled brush to remove the paint from the roller frame and handle. If you are cleaning a paint tray, you may need to use a stiff-bristled brush or pour a small amount of mineral spirits into the paint tray to remove dried paint. Set the frame aside to air-dry.
If you are taking a short break during a painting session, place the roller in a large plastic bag and tie the bag shut around the handle. Slip the paint tray into a separate bag and tie it shut as well. This will prevent the paint from drying until you can get back to work.

Allow the roller to air dry upright or on a hanger
After cleaning your paint roller, it is important to let it dry properly. Leaving your roller to air dry upright on its end or on a hanger will ensure that the fibres retain their shape. Allowing the roller to dry on its side will cause the fibres to flatten, which will negatively impact your painting.
If you are taking a break from painting and will be returning to the same paint pot, you can wrap your roller in cling film or aluminium foil to prevent the paint from drying out. This will save you time and paint. However, if you have finished painting for the day, you should clean your roller thoroughly and let it air dry.
If you are using oil-based paint, you will need to clean your roller with a solvent such as mineral spirits or a specialist brush cleaner. This will ensure that the paint is fully removed from the roller. Once you have cleaned the roller with the solvent, you will need to rinse it with warm water and dish soap to remove any remaining solvent.
For water-based paints, rinsing the roller with cold water first will help to remove most of the paint. Then, you can use warm water and a small amount of dish soap to clean the roller fully. It is important to remove as much excess paint as possible before using warm water, as hot water can cause certain paints to congeal and dry within the roller, making it more difficult to clean.
Once you have cleaned your roller and removed all the paint, you can let it air dry upright or on a hanger. This will ensure that the roller is ready for your next painting project.
