It’s easy to forget to wear protective clothing, especially if you’re used to handling DIY projects like applying polyurethane finishes. However, did you know that prolonged exposure to these harsh chemicals can harm human skin?
To prevent such accidents, our woodworking experts detailed how to get polyurethane off your hands and other tips about the removal process.
Polyurethane and its Properties
Polyurethane bonds well with other materials because it’s categorized as a synthetic resin. You may not know, but it’s a chemical derived from petroleum. So even though it’s a popular wood finish product, you can also use it in insulation and sealing tasks.
When shopping for these wood finishes, you’ll encounter two variations: oil-based and water-based polyurethane products. These options have different components and textures, so don’t expect the same procedure when removing polyurethane from your hands.
Assess the Type of Poly That Sticks on Your Hands
It’s easy to differentiate oil-based poly from water-based polyurethane. All you need to do is feel the texture of the polyurethane stuck in your hands.
If the sticky substance gives you a strong and greasy feeling, there’s a high chance that it’s an oil-based polyurethane finish. It’s often composed of harsh chemicals that stain with a brown or amber hue.
Meanwhile, water-based polyurethane has a lighter consistency than oil-based alternatives. Because of this, it’s easier to remove and prevent polyurethane from sticking.
Removing Water-Based Poly
Step #1: Wash Poly Off Your Hands
Before anything else, wash your hands with liquid dish soap and water. By doing this, you’ll be able to remove dome residues of dried polyurethane.
Step #2: Rub Your Hands and Rinse Them Off Thoroughly
As you apply the dishwashing soap and warm water, don’t forget to rub your hands together thoroughly. You can also try gently rubbing the sticky spots to wash polyurethane off your hands faster.
If you still can’t remove polyurethane stains with this method, our resident woodworkers recommend soaking your hands in the water and dish soap solution for a few minutes. It should soften the dried polyurethane and allow easier removal.
Hand sanitizers can also be an alternative to dish soap, but will denatured alcohol remove polyurethane? The short answer is yes. You can also count on a fingernail polish remover to wash polyurethane from your hands.
After removing the polyurethane finish from the affected area, grab a soft towel and dry your hand.
Step #3: Apply a Lotion Moisturizer
All these methods can help to get polyurethane off your hands, but excessive rubbing could dry your skin. Unfortunately, rubbing alcohol  in dry areas can disrupt skin barriers. Because of this, we suggest using hand lotion after the process.
Removing Oil-Based Poly
Step #1: Apply Mineral Spirits on Your Hands
Oil-based or not, the question of will mineral spirits can remove polyurethane finishes always results in a resounding yes. Besides mineral spirits, you must have soap, warm water, vegetable oil (or baby oil), and moisturizing lotion at your disposal.
When applying mineral spirits to remove oil-based polyurethane from your hands, you must ensure that you’re in a well-ventilated area. The more sticky the spot is, the more mineral spirits you should wash your hands with.
Be extra cautious in applying mineral spirits because these chemicals are often harsh on the skin. You can use a shop rag to control the application. Nevertheless, it’ll soften and lift polyurethane.
While mineral spirits tend to remove oil-based polyurethane stains from your hands, you can opt for alternatives like a soy-based polyurethane stripper or paint thinner. Rubbing alcohol or a nail polish remover should also help with sticky polyurethane.
Step #2: Clean Your Hands
After that, you need to remove the mineral spirits from your skin as they are known to be acidic. If you can, rinse it off with lava soap or dishwashing liquid.
Removing polyurethane isn’t as easy as you think because it can still leave your hand sticky after pouring all that mineral spirits. If you still feel that texture, you can repeat applying mineral spirits and washing it off with warm water until the stickiness is gone.
Step #3: Apply Lotion Moisturizer
All the excessive washing will leave your hand dry, so applying a moisturizing lotion can be crucial to this process. Don’t just grab any hand lotion on the shelves and ensure that the product fits your skin condition.
