Getting Started with Equipment

When you’re starting out, it’s not always necessary to invest heavily in equipment. Barry shares his experience:

  • Rent Before You Buy: Renting equipment can be a cost-effective way to get started. Look for local rental services to source a pressure washer trailer. This approach allows you to fulfill contracts without the upfront cost of purchasing equipment.
  • Save and Reinvest: Use the profits from your jobs to gradually buy your own equipment. Within a few months, you can potentially own a new pressure washer trailer without going into debt.
  • Start Small: Even with lower-end equipment like a 3.5-gallon-per-minute cold water washer, you can begin servicing gas stations and upgrade as your business grows.

Essential Chemicals for Gas Station Cleaning

Using the right chemicals is crucial for effective cleaning. Barry recommends:

  • Sodium Hydroxide: This versatile chemical is excellent for breaking down grease and oil. Barry’s go-to mixture includes sodium hydroxide and blue Dawn detergent.
  • Mixing Instructions: Always mix sodium hydroxide with cold water, adding the water first to avoid heat reactions. Use about a cup (16 ounces) of sodium hydroxide per gallon of water, and always mix in an open area with proper safety gear.
  • Safety Precautions: Wear protective gear such as a full-face plastic mask, long-sleeve gloves, and a mask to avoid exposure to fumes and splashes. Safety is paramount when handling strong chemicals.

Pro Tips for Successful Pressure Washing

Barry offers additional advice to ensure success in the pressure washing industry:

  • Hot Water Systems: For thorough cleaning of grease, food, and beverage stains, especially in high-traffic areas like gas stations, hot water systems are highly effective.
  • Chemical Knowledge: Understanding the chemicals you’re using is crucial. Avoid mixing incompatible chemicals to prevent dangerous reactions. Seek advice from local chemical suppliers or pressure washer stores.
