We use several personal grooming products such as soap, body wash, and shampoo in our bathroom daily. And these products form grime on the shower door over time. 

However, regular maintenance is necessary to ensure your shower door retains its shine. But you must use the right cleaner to get the job done with ease.  

The thing is each type of dirt requires a specific cleaner but universal cleaning options are available. WD-40 is an excellent versatile cleaning option for shower doors. But how to use it appropriately has been the challenge for many. 

We’ll explain how to use WD-40 to clean shower doors. Read to learn more!

How To Clean Shower Doors With WD-40

Follow the steps below to clean shower doors with WD-40.

  • Spray a generous coat of WD-40 on the shower door and wait for 15 minutes.
  • Rub the shower door with a clean fabric. Microfiber cloths are the best materials for this purpose, but any clean cloth will suffice. 
  • Repeat the process if the dirt remains until it goes off.
  • Use a sponge or a plastic sponge for stubborn stains.

Caution: Some WD-40 may spill to the shower floor during cleaning. After cleaning the shower floor, wipe them off to avoid slipping and hurting yourself.

What Is WD-40

WD-40 is a unique lubricant containing anti-corrosion, water displacement, penetration, and fifth removal agents. WD stands for water displacement. 

WD-40 is a multi-purpose product with a handy aerosol spray container with versatile applications. 

Applications Of WD-40

WD-40 has many uses, including the following.

  • WD-40 removes filth, tar, grease, gum, scuff marks, adhesives, and water deposits.
  • WD-40 can also remove corrosion from tools, weapons, mechanical equipment, and sporting equipment. 
  • WD-40 lubricates and protects hinges, wheels, rollers, chains, and gears, among other things, from corrosion. 
  • WD-40 also restores equipment in addition to cleaning anti-corrosion functions. It can restore spark plugs, engines, and power tools.

Composition Of WD-40

WD-40’s formulation has been a closely guarded secret for many years. The formulators did not patent the product to avoid divulging its composition.

However, the results of a recent gas spectrometry test conducted on a WD-40 sample revealed the chemical composition of the famous cleaning and lubrication agent.

The test revealed that WD-40 contains mineral oils, hydrocarbons, and carbon dioxide. Mineral oils such as vaseline, baby oil, and the goop inside lava lamps are present in WD-40. 

WD-40 is also rich in alkanes such as cyclohexane, nonane, decane, tetradecane, and dimethyl naphthalene.

Alkanes are water-repellent because their hydrogen atoms do not have a charge and cannot attach to the hydrogen or oxygen in the water. This explains the water displacement (WD) property of WD-40.

The cyclo prefix indicates a ring structure rather than a chain. Cycloalkanes have a higher melting point due to their ring structure.

Decane helps WD-40 stay liquid at very low temperatures. Decane does not freeze until it reaches a temperature of roughly -21 degrees Fahrenheit.

Safe Use Of WD-40

WD-40 is a lubricant with many useful applications. However, usage requires caution. Take the following precautions when using WD-40.

  • Avoid eye contact when spraying. Contact with the eyes may cause irritation. Tearing and redness are possible side effects.
  • Keep your hands away from your skin for as long as possible. Long-term and repetitive contact can cause minor irritation and defatting, as well as dermatitis. Wash with soap and water after use.
  • Only use it in a well-ventilated area and wear a nose mask. High amounts can induce nasal and respiratory irritation, headaches, dizziness, and nausea.
  • Unplug all electrical tools, motors, and appliances nearby before spraying. Electricity can bore a hole in the can and ignite the contents into flames.
  • Keep the can away from battery terminals, electrical connections on motors, and other appliances to avoid fire accidents.
