Pressure Washer or Garden Hose

Pressure Washers have a higher water pressure than garden hoses, which makes them better at removing tough dirt, grime, and stains. They can also be used to clean surfaces that are difficult to reach with a garden hose, such as the underside of a car or the roof of a house. However, pressure washers can be more dangerous than garden hoses, as they can easily damage delicate surfaces if used improperly.

Garden Hoses are less powerful than pressure washers, but they are also less dangerous. They are a good choice for everyday cleaning tasks, such as washing the car or watering the lawn. Garden hoses are also more affordable than pressure washers.

Which one is right for you? If you need to clean tough dirt, grime, or stains, a pressure washer is the better option. However, if you are just looking for a tool to do everyday cleaning tasks, a garden hose is a good choice.

Auto Body Solvent

Auto body solvent is a type of solvent that is used to clean and prepare automotive surfaces for painting or other finishing treatments. It is a powerful solvent that can remove a variety of contaminants, including grease, tar, oil, and wax. Auto body solvent is also effective at removing paint overspray, rust, and other blemishes.

Auto body solvent is available in a variety of forms, including aerosol cans, bottles, and drums. It is important to choose the right type of solvent for the job. For example, aerosol cans are convenient for spot cleaning, while bottles and drums are better for larger areas.

When using auto body solvent, it is important to take safety precautions. Always wear gloves and eye protection when handling solvent. It is also important to work in a well-ventilated area. Solvent fumes can be harmful if inhaled.



WD-40 is a brand of penetrating oil and water-displacement spray. It was developed in 1953 by Norm Larsen, founder of the Rocket Chemical Company, in San Diego, California. WD-40 stands for Water Displacement, 40th formula.

  • Lubricating squeaky hinges, locks, and other moving parts
  • Removing rust and corrosion
  • Protecting metal surfaces from rust and corrosion
  • Cleaning and degreasing surfaces
  • Removing adhesive residue
  • Loosening stuck bolts and screws

WD-40 is a safe product to use around the home, but it is important to follow the directions on the label. WD-40 should not be used on electrical equipment or in open flames.
