The Ultimate Guide to Cleaning and Maintaining Polyurethane Surfaces

Polyurethane is a type of polymer that is commonly used to coat surfaces in order to protect them from wear and tear. It is often applied to wood, metal, and concrete surfaces to provide a durable and long-lasting finish. While polyurethane is a great option for protecting your surfaces, it can be a bit of a challenge to clean.

In this guide, we’ll cover everything you need to know about cleaning polyurethane surfaces, including the best methods and products to use.

What can I use to clean polyurethane?

First things first, it’s important to understand that different types of polyurethane require different methods of cleaning. There are two main types of polyurethane: oil-based and water-based. Oil-based polyurethane is the older of the two, and it is made from a combination of oil and polyurethane resins. On the other hand, water-based polyurethane is made from a combination of water and polyurethane resins. Both types of polyurethane are durable and long-lasting, but they do require different cleaning methods.

Cleaning Oil-Based Polyurethane

Oil-based polyurethane is known for its warm, amber color and its ability to highlight the natural grain of wood. It is a popular choice for furniture and flooring, but it can be a bit more challenging to clean than water-based polyurethane. Here are some tips for cleaning oil-based polyurethane:

1. Use a mild detergent and water: Start by mixing a small amount of mild detergent with warm water in a bucket. Dip a soft cloth or sponge into the solution and gently scrub the surface. Be sure to wring out the cloth or sponge before wiping the surface to avoid excess water.
2. Avoid abrasive cleaners: Abrasive cleaners can scratch the surface of the polyurethane and dull its shine. Instead, opt for a mild detergent or a specialized cleaner made specifically for oil-based polyurethane.
3. Wipe dry: Once you’ve finished scrubbing the surface, be sure to wipe it dry with a clean, dry cloth. This will help prevent water spots and streaks from forming.
4. Use a furniture polish: To give your oil-based polyurethane a nice shine, consider using a furniture polish. Simply apply a small amount of polish to a soft cloth and wipe it over the surface in a circular motion. This will help restore the shine and protect the surface from dirt and grime.

Cleaning Water-Based Polyurethane

Water-based polyurethane is a newer type of polyurethane that has gained popularity in recent years due to its quick drying time and low toxicity. It is a clear finish that is often used on wood flooring, cabinetry, and furniture. Here are some tips for cleaning water-based polyurethane:

1. Use a mild detergent and water: Just like with oil-based polyurethane, you’ll want to start by mixing a small amount of mild detergent with warm water in a bucket. Dip a soft cloth or sponge into the solution and gently scrub the surface. Be sure to wring out the cloth or sponge before wiping the surface to avoid excess water.
2. Avoid abrasive cleaners: Abrasive cleaners can scratch the surface of the polyurethane and dull its shine. Instead, opt for a mild detergent or a specialized cleaner made specifically for water-based polyurethane.
3. Wipe dry: Once you have finished scrubbing the surface, be sure to wipe it dry with a clean, dry cloth. This will help prevent water spots and streaks from forming.
4. Use a furniture polish: To give your water-based polyurethane a nice shine, consider using a furniture polish. Simply apply a small amount of polish to a soft cloth and wipe it over the surface in a circular motion. This will help restore the shine and protect the surface from dirt and grime.
5. Avoid using wax: While wax may be effective at protecting and shining other types of surfaces, it is not recommended for use on water-based polyurethane. The wax can create a barrier that prevents the polyurethane from adhering properly, causing it to peel or flake over time.

Removing Stains from Polyurethane Surfaces

Accidents happen, and you’ll inevitably encounter stains on your polyurethane surfaces at some point. The key to removing stains is to act quickly and use the right products. Here are some tips for removing common types of stains from polyurethane surfaces:

Grease and oil stains:

For grease and oil stains, start by blotting the stain with a clean, dry cloth to absorb as much of the grease or oil as possible. Then, apply a small amount of dish soap to the stain and gently scrub it with a soft cloth or sponge. Rinse the surface with warm water and wipe it dry.

Ink stains:

Ink stains can be tricky to remove, but it’s not impossible. Start by blotting the stain with a clean, dry cloth to absorb as much of the ink as possible. Then, try using a small amount of rubbing alcohol or hair spray (either one should work) on a cotton swab to scrub the stain gently. Rinse the surface with warm water and wipe it dry.

Red wine stains:

Red wine stains can be a nightmare to remove, but there are a few steps you can take to minimize the damage. First, blot the stain with a clean, dry cloth to absorb as much of the wine as possible. Then, mix equal parts white vinegar and water in a small bowl and apply it to the stain with a soft cloth or sponge. Gently scrub the stain, rinse the surface with warm water, and wipe it dry.

Blood stains:

Blood stains can be difficult to remove, but it’s important to act quickly before the stain has a chance to set. Start by blotting the stain with a clean, dry cloth to absorb as much of the blood as possible. Then, mix equal parts water and hydrogen peroxide in a small bowl and apply it to the stain with a soft cloth or sponge. Gently scrub the stain, rinse the surface with warm water, and wipe it dry.

Water stains:

These are the most common dirt particles that harm your polyurethane wood surface. It could be an eyesore that will make you second guess whether the wood piece has a stain.

To safely remove a water stain;

• Use baking soda. Mix one tablespoon of baking soda with one tablespoon of water to form a paste.
• Gently rub the water stain until it is removed using a clean cloth or rag. Do not rub roughly to avoid making a permanent mark on the surface.
• Use vinegar. To remove a water stain, add olive oil to a small portion of vinegar. 
• After mixing the oil and vinegar, apply a clean cloth to the stain. Use a small circular motion to wipe the stain until it is gone.
• Use petroleum jelly. Before going to bed, take a small amount of petroleum jelly and place it on the water ring on the wood. Allow it to sit overnight and wipe clean in the morning to get a refreshed spot on the wood surface, making it appear new.
• Non-gel toothpaste. Take a small amount of non-gel toothpaste and apply it to a clean cloth. Gently wipe the watermark using a circular motion until it’s gone.

Tips for Maintaining Polyurethane Surfaces

Cleaning and maintaining your polyurethane surfaces is essential to keeping them looking their best. Here are a few tips to help you maintain your polyurethane surfaces:

• Dust regularly: Dust and dirt can build up on your polyurethane surfaces over time, causing them to look dull and lifeless. To prevent this, be sure to dust your surfaces regularly using a soft cloth or a feather duster.

• Use coasters and placemats: To prevent water rings and stains from forming on your polyurethane surfaces, be sure to use coasters and placemats whenever possible. This will help protect the surface from spills and other accidental damage.

• Avoid placing hot items directly on the surface: Polyurethane is resistant to heat but is not completely immune to it. Avoid placing hot items directly on the surface to prevent damage to your polyurethane surfaces. This includes things like pots and pans, coffee mugs, and other hot objects.
• Protect the surface from moisture: Water can be damaging to polyurethane surfaces, especially if it is left to sit for an extended period of time. To prevent moisture damage, be sure to wipe up any spills as soon as they occur and avoid leaving damp items on the surface.
• Use protective pads: If you have furniture with polyurethane surfaces, consider using protective pads to prevent scratches and dents. These pads are typically made from felt or rubber and can be placed on the bottom of furniture legs to prevent them from coming into contact with the floor.
