Can You Use WD-40 On Squeaky Wood? The Complete Guide

WD-40 is a popular household lubricant known for its versatility in fixing squeaks, stuck parts, and other minor mechanical issues. But can you use it on squeaky wood floors and furniture?

WD-40 can be used on squeaky wood if the noise is caused by friction between boards or parts. However, it provides only a temporary fix since the lubricant wears off over time. WD-40 also poses some risks like flammability and slipping.

Wood can start squeaking for various reasons like natural contraction and expansion of boards, loose joints, gaps between floorboards, and friction between components. WD-40 is effective at reducing squeaks caused by friction but doesn’t address other underlying issues.

This article provides a detailed overview of using WD-40 on squeaky wood. We’ll cover:

  • Common causes of squeaky wood and floors
  • How WD-40 works to reduce squeaks
  • Pros and cons of using WD-40 on wood
  • Step-by-step directions to apply it correctly
  • Safer alternatives for a more permanent solution
  • When to call a professional instead

What Causes Wood Floors and Furniture to Squeak?

Wood naturally contracts and expands with changes in temperature and humidity. Over time, this dynamic movement can cause boards and joints to rub against each other, resulting in squeaking and creaking noises.

The most common causes of squeaky wood are:

  • Gaps between floorboards – Contraction opens up spaces between floorboards that rub together when stepped on. This allows the boards to flex and squeak.
  • Loose joints – Connections between boards can come loose over years of use. Any back-and-forth movement at the joint will cause squeaking.
  • Warped boards – Improper installation or water damage can warp boards out of alignment. The uneven surfaces rubbing together make noise.
  • Joist separation – Space between the joist (supporting wood beams) and subfloor allows the floor to flex and squeak when walked on.
  • Friction – Direct contact between components like tongue-and-groove boards or chair joints creates friction and squeaking.

WD-40 can only resolve squeaks caused by friction. It lubricates the contact points between boards and parts so they glide smoothly instead of grinding. WD-40 does not address structural issues like floor gaps, loose joints, or warped boards.

How Does WD-40 Work to Reduce Wood Squeaks?

WD-40 is a light oil-based lubricant. It temporarily coats surfaces to reduce friction and increase slickness. The product seeps into tiny crevices to lubricate parts that directly rub together and cause squeaking.

Some key qualities that allow WD-40 to reduce wood squeaks include:

  • Low viscosity – The thin consistency enables WD-40 to penetrate tight spaces between boards and joints.
  • Slippery feel – Its oily composition lubricates wood-on-wood contact points so they slide smoothly.
  • Temporary coating – A light application creates a slick barrier between surfaces without leaving an oily mess.
  • Quick drying – The carrier solvents evaporate to leave behind the lubricating oils.

The lubricating effect minimizes grinding friction that creates squeaking. But it only works on accessible contact points and does not solve underlying structural issues.

Pros and Cons of Using WD-40 on Squeaky Wood

Here are some benefits as well as risks to consider when using WD-40 to stop wood squeaking:


  • Widely available – As a common household item, WD-40 can be picked up at any hardware store or ordered online.
  • Easy to apply – You simply spray it directly onto the affected area and penetrating action does the rest.
  • Cheap solution – At $5 to $10 per can, WD-40 provides an affordable quick fix.
  • Non-damaging – When used properly, it will not harm or stain most wood finishes.


  • WD-40 is not a permanent solution – It may need reapplied multiple times as the lubricating effect can wear off over time. The squeaks are likely to return after a while.
  • It doesn’t address underlying causes – WD-40 only reduces friction, it doesn’t fix issues like loose floorboards, uneven subfloors, etc. The root problems causing the squeaking are still present.
  • Possible messiness – WD-40 can drip between floorboards and leave a slippery residue if too much is applied. It should be used sparingly.
  • Not ideal for finished wood – The chemicals in WD-40 could potentially harm some wood finishes. Test on an inconspicuous area first. Oil-based WD-40 may discolor raw wood or break down shellac finishes.
  • Only treats symptom – Does not address the root structural problems causing noise.
  • Flammable – Contains petroleum distillates that are extremely flammable, especially before carrier solvents evaporate.
  • Slippery – Excess spray can create a temporarily slippery surface, increasing fall risk.

For these reasons, WD-40 is best suited for quickly silencing minor isolated squeaks caused by friction. It does not provide a complete solution for chronic wood squeaking issues.

How to Apply WD-40 to Squeaky Wood Floors and Furniture

If you choose to use WD-40 on a squeaky wood surface, follow these steps:

Prep Work

  • Clear the area of people, pets, furniture, and other obstructions. Provide adequate ventilation.
  • Remove any dust, dirt, or grime to allow WD-40 to reach the wood surface.
  • Test product on an inconspicuous spot first to check for any discoloration or damage to the wood.


  • Shake the WD-40 can vigorously for 30 seconds before use.
  • Insert the red straw into the nozzle and bend it to reach tight areas.
  • Hold the straw 1-2 inches from the affected area and spray short bursts into crevices. Avoid overspray.
  • Let WD-40 penetrate for 2-3 minutes. Reapply if the squeak persists.
  • Wipe away all excess liquid using a clean dry cloth. Buff dry.
  • Allow the area to ventilate and fully dry for at least 1-2 hours before use.

Be conservative with application to avoid a slippery, oily mess. Reapply every few months or as needed when squeaks return. Promptly clean up any drips or spills.

Safer WD-40 Alternatives for Squeaky Wood

While WD-40 can provide a quick fix for isolated wood squeaks, its flammable and temporary properties make it less than ideal. Some safer alternatives include:

  • Talcum powder – The powder seeps into cracks to lubricate wood-on-wood contact.
  • Bar soap – Rubbing a bar of soap on the affected area lubricates effectively without the mess.
  • Cooking oil – A small amount of vegetable, olive, or coconut oil applied with a cloth works well.
  • Paraffin wax – Melted paraffin wax sets into a slippery solid lubricant between boards.
  • Graphite powder – The ultra-slick carbon powder sprinkled on crevices smoothens wood friction.
  • Silicone spray – Specialized silicone lubricants work well and contain less volatile solvents.
  • Adhesive felt pads – Applied to furniture feet, they prevent friction that causes squeaking.

These alternatives offer more permanent and less risky lubrication than WD-40 for squeaky wood.

Effective Solution To Fix Squeaky Floor

While WD-40 lubricates to reduce friction between floorboards, it doesn’t address any of these root causes. That’s why the squeak relief it provides is only temporary. Permanently stopping squeaks requires fixing the underlying problems.

Here are the most effective solutions for each issue:

  • Reattach loose boards – Drive in new nails or screws to pull gapping floorboards tightly back together.
  • Fill shrinkage gaps – Inject wood filler into gaps between boards to prevent rubbing and noise.
  • Add braces – Structural bracing underneath helps stabilize weak areas prone to flexing.
  • Improve subfloor – Fix moisture issues, replace warped panels, or add stiffeners to create a more solid base.
  • Adjust floor layout – Strategically rearrange heavy objects to better distribute weight across floor joists.
  • Humidity control – Maintaining 40-45% humidity helps minimize seasonal wood expansion/contraction.

Permanently stopping squeaks requires a custom approach based on inspecting and identifying their specific cause in each case. WD-40 lubricates temporarily but a lasting solution involves resolving the source of the problem through skilled repair techniques.

When to Call a Professional for Squeaky Wood Floors

If you have extensive squeaking across large areas or excessive noise when walking, the underlying cause is likely a structural issue. In such cases, DIY lubricants provide only a temporary band-aid solution.

Signs that professionals should address the squeaky wood floor include:

  • Squeaking noises across most of the floor.
  • Very loud squeaks or creaking noises when walked on.
  • Uneven surfaces or noticeable sagging.
  • Cracks or gaps wider than a dime between boards.
  • Doors or windows that stick from building settling.

A contractor can identify and fix the real problem instead of just silencing the symptoms. Typical structural solutions include:

  • Refastening loose floorboards with deck screws
  • Replacing damaged or warped subfloor sections
  • Filling gaps with wood filler then refinishing
  • Gluing down tongues and grooves with construction adhesive
  • Installing rigid blocking between floor joists
  • Leveling uneven spots with shims

Get an inspection and professional repair estimate if DIY squeak fixes don’t work. This will prevent further deterioration and avoid bigger headaches down the road.

Does WD-40 Work on Squeaky Hardwood, Engineered or Laminate Floors?

You can use WD-40 on solid hardwood, engineered wood, and laminate floors to help quiet squeaks temporarily. However, each flooring type has some unique considerations:

Solid Hardwood Floors

  • Use caution on finished surfaces – Test WD-40 in an inconspicuous spot first to avoid damaging the finish.
  • Effective for unfinished surfaces – WD-40 penetrates into bare wood well for direct lubrication.
  • Won’t address wood shrinkage – The main cause of squeaks in solid hardwood over time as boards shrink.

Engineered Wood Floors

  • Safer for factory finishes – More compatible with engineered wood’s aluminum oxide finish.
  • Penetrates plywood core – The spray can reach the inner plywood layers prone to subtle expansion/contraction.
  • Minimizes wood movement – Engineered wood is more dimensionally stable than solid wood.

Laminate Floors

  • Avoid seams – Don’t spray WD-40 directly into seams between laminate boards to prevent swelling damage.
  • Spray under baseboards – Apply along the perimeter beneath trim to lubricate the floor’s edge.
  • Loose panels are main cause – Fix any locking mechanisms that have come undone between laminate planks.

WD-40 can provide temporary squeak relief for all three types of wood flooring. But the effectiveness and risks vary somewhat for each material based on their construction. Proper precautions should be taken.

Squeaky Floor Home Remedies and Folklore: Do They Actually Work?

There are a variety of home remedies for fixing squeaky floors that have become popular over the years. But do these folklore fixes actually work? Here’s an assessment:

Sprinkle Baby Powder

  • The claim – The powder will dry out damp boards and lubricate joints.
  • The reality – It provides very minor and temporary improvement in sound. Moisture is rarely the cause.

Use Bar Soap

  • The claim – Rubbing a bar of soap on the floor lubricates and quiets squeaks.
  • The reality – Like graphite powder, it helps briefly but doesn’t address root causes. The lubrication wears off quickly.

Remove Carpet Tacks

  • The claim – Left behind carpet tacks pop and snap under pressure, causing noises mistaken for squeaks.
  • The reality – While a sensible precaution, tacks rarely make sounds identical to structural floor squeaks.

Turn Screws into Squeaky Floor

  • The claim – This will draw boards tighter together and stop squeaking.
  • The reality – Ineffective since random screws do not pull in gaps at the source, and may even create new ones.

These and other home remedies can provide very minor, temporary improvements in floor sounds. But they should not be expected to come close to fully resolving true structural squeaks caused by issues like loose boards, unlevel subfloors, etc. They are more folklore than fact.


WD-40 can offer short-term relief for squeaky wood floors by lubricating surfaces. But it doesn’t fix underlying problems causing noises so squeaks inevitably return over time.

Permanent solutions require professional floor repairs tailored to the specific cause in each unique case. For the greatest success eliminating squeaks long-term, it’s best to have the floor assessed by a qualified contractor.

  • Apply sparingly only to squeaky spots and wipe away excess for best results.
  • Factors like wood shrinkage, poor installation, structural settling cause floor squeaks.
  • Permanent squeak-proofing involves repairs like reattaching loose boards, adding braces, and humidity control.
  • Alternatives like powders and glue provide minor, temporary relief similar to WD-40.
  • Use caution when applying to finished surfaces and seams between floorboards.
  • Home remedies may help a little but don’t resolve the root causes of floor squeaking
