BUS WASHING: What operators need to know BUSRide called on leading bus wash OEMs for best practices, pitfalls to avoid and critical points to fit the most effective, cost efficient system to the company and fleet.

Why is a bus wash system important to the company?

Nothing makes a better first impression on the paying customers than the arrival of a clean, shiny bus or motorcoach.

A clean bus is statistically safer and easier to maintain, and the vehicle stands a better chance of a longer operating cycle.

Thorough bus washing on a regular basis protects all exterior surfaces from the elements and corrosive contaminants. In the advent of bus-wrap advertising and upscale graphic design, extra care to the exterior surfaces of buses and coaches has become a greater concern.

The capability of cleaning the undercarriage is particularly important in regions where harsh winters require corrosive salts and chlorides to clear slippery roads. These chemicals wreak havoc on exposed steel bus frames.

Scheduled washes using the correct system are essential to reducing damage and structural repairs. Taking control of bus washing controls the company’s image and can be the least expensive way to meet quality assurance and quality control.

What are the types of bus wash systems?

As bus companies and transit agencies vary greatly, each wash system is highly customized to meet specific needs according to fleet size and vehicle makeup. The necessary components may include more than one brush or mitter system, and range from one to multiple high-pressure stations with pre-soap, high-pressure rinse, spot free rinse or wax capability. Some will institute blowers to hasten the drying time as the bus exits the wash bay.

Gantry systems wash buses in a stationary position, as brushes, mops and touchless sprayers on tracks, move over the vehicle and down the side, front to back.

Drive-through systems remain stationary as the driver moves the vehicle through the brushes, sprayers, product dispensers and dryers.

Tower or walkaround systems are cost-effective solutions for small fleets, easily moved by hand around the vehicle as the rotating brush sprays, scrubs and rotates. With their low price point and versatility, a company of any size can use these systems — as the main wash source for small fleets or for larger fleets to use a tool for odd size washing, or backup should the permanent automatic system break down.

Undercarriage wash systems are of interest to operators doing business in harsh, corrosive-prone winter environments.

Standalone undercarriage systems combine chloride neutralizing with corrosion inhibition and protection.

Measured against corrosion repair costs, this specialized system offers exceptional ROI. What determines the system bus and coach operators should consider?

Where large transit bus and coach fleets may require 30 washes an hour and up to hundreds per day, automated drive-through and gantry systems are the answer. The greatest demand is for wash systems that can handle five to 40 buses per shift.

For the company that must move several hundred buses through the system at night, or before the drivers leave their shift, the drive-through is the most popular solution.

The rollover gantry removes the driver from the equation and typically takes no more than 5 to 8 minutes per wash cycle. Gantry systems tend to work most effectively when service schedules are not as tight and the desire is for a higher level of wash quality.

Bus yards and garage facilities vary in size and layout from one operation to the next, each with separate specifications

for the optimum wash equipment. Autonomous single-brush bus washers are especially applicable for challenged space and budget situations.

What do operators need to know about bus wash systems they may not already know?

A bus wash system is not a do-it-yourself project kit.

Selecting and configuring the most appropriate system involves the operator working closely with the wash system OEM to determine the most effective solution for the fleet in the space available.

The system must fit and function properly, allowing adequate access to electric utilities, water supply and proper sewer drainage.

During design and installation, operators need to be aware of the capacity and restrictions of all utilities, and ensure the parameters and specifications match those the OEM recommends.

The wash bay footprint must allow the correct placement of all the controls and leave adequate room for vehicles to enter and exit safely.

Benchmarking is helpful. Few operators know their cost per wash, which considers the estimated life cycle of the system, annual maintenance costs and costs of wash products, as well as required time and labor. The advantage of this metric is knowing precisely what the company spends on this function.

Understanding the exact cost affords an opportunity to make the wash process more cost efficient.

the independent variable. Impatient drivers can move the bus through the cycle too fast for a complete and thorough wash, often resulting in damage to the bus and the wash equipment.

Some drive-through systems incorporate speed control sensing devices that track the bus through the wash at specified intervals.

What role does technology play in bus wash systems?

Until recently, bus wash systems were a mechanical function. The influx of electronic sensing and monitoring technology has advanced the wash process, and the benefits and savings are apparent.

Bus wash OEMs continue to implement technologies that refine the process, improve quality and lower costs by conserving water, products and electricity. Technology has brought metered soap systems, improved mitter systems, water softening and mineral removal.

How important is the choice of chemicals and wash products?

The correct mix of chemicals has as much an impact on the quality of the wash as the equipment itself.

Aside from utility costs over time, the bus wash chemicals and cleaning products constitute the biggest expense. However, a modern bus wash system can save as much as 25 percent in chemical usage compared to older systems, simply because the new wash systems are more effective at metering usage to consistent levels.

What are the greatest concerns in the operation of the wash system?

In a drive-through system that is most effective when the bus is moving approximately 1.5 feet per second, the bus driver is

What are the water drainage requirements?

The most important question in the long-term use of a bus wash system is whether to incorporate a reclaimed water system

What are the environmental concerns in a bus wash operation?

For the most part, today’s wash chemicals are much friendlier to the environment, removed simply enough through normal sewer drain systems. For all intents and purposes, hazardous waste removal systems are unnecessary for modern wash systems.

Where there is no federal protocol, with each municipality, county or state establishing its own level of wastewater tolerances, this is somewhat a controversial red herring.

Nonetheless, the industry has complied with better technology and decreased use of acid products, which most operators no longer even consider an option.

— easily the best choice for reducing water usage. Depending on the complexity of the system and the overall configuration, the typical recycling system can recapture on average up to 80 percent of the water used for each wash. A system with advanced technology can control water usage even more.

Except for the soap, totally loop-closed reclamation systems filter everything out effectively for washing only. Rinses require only a minimum amount of necessary freshwater.

While this is premium from a conservation standpoint, the costs are much higher

WASH DYNAMICS

What are the recommended maintenance requirements?

Operators often overlook or underestimate their maintenance needs, as well as their available manpower to operate and maintain the bus wash system. Preventative maintenance naturally ensures longevity and better use over the system’s life cycle. The OEM recommendation is to adhere to the recommended maintenance schedule and assign a technician to specifically monitor the wash system and keep it in working order. The job requires someone with mechanical aptitude, because of the multiple hydraulic, electric, water and air pressure systems, as well as automated, computerized control systems at work in the wash bay.

In the area of bus washing, what pitfalls should an operator work to avoid?

Do not view the wash system as a magical solution for a fleet of any size with every type of bus. Every available system comes with advantages as well as limitations. Know what to expect and do not ask more from the system than can it accommodate with normal use.

Polyurea coating Could it save your wash bay?

By Mark Ellis and Justin Tripp The use of polyurea coatings in maintenance facilities has been increasing in popularity for the past decade, although their use in automotive and facility applications has been around for nearly 30 years. Traditionally, polyurea coatings have been used to line the inside of truck beds to protect the underlying metal from weather and other corrosive elements, and to provide for easier clean up. This principle also applies when polyurea coatings are used on wash bay floors and walls in maintenance facilities. Not only does the coating protect the underlying floors and walls, but it also allows for ease of cleaning these surfaces.

What is polyurea?

Polyurea is a chemical mixture of an isocyanate compound and a resin blend. When these two chemicals are mixed and introduced to compressed air, they form a hardened rubberlike compound that, when applied correctly and dried, forms a completely sealed coating that is impervious and easy to clean.

How is it applied?

The most common way to apply a polyurea coating to a surface is by spraying it with special equipment. The preferred method to quickly cover large areas like wash bays is by using a machine that draws the chemicals from two separate drums into a paintlike sprayer. Since the chemicals come from bulk supply drums, it expedites the coating process. Also, this application machine has a control panel that adjusts the speed of the chemical mix along with how much air is being released. This helps deliver the coating in a consistent even layer.

What are the benefits?

Paint, epoxy and other coatings are the traditional ways to protect surfaces in harsh wash and maintenance facility areas. However, when these coatings are used in a wash bay or a maintenance pit where they are exposed to grease, dirt and moisture, they begin to lose their protective qualities.

Paint begins to fade and flake away over time and with repetitive exposure to a pressure washer. Paint also scratches and releases very easily, exposing the underlying surface to moisture and contaminants.

Polyurea coatings, unlike traditional paints and coatings, hold up against abrasion, corrosion, pressure washing and temperature changes. In addition to protecting the surface, polyurea also strengthens the structure because it is a solid coating across the entire area without gaps or end points. The material is somewhat flexible and allows for expansion and contraction with weather changes, and it completely seals

Polyurea coatings hold up against abrasion, corrosion, pressure washing and temperature changes.

so no moisture will penetrate through to the surface that is being protected. Polyurea coatings also protect against many chemicals that can pass through paint. As for cleaning, grease and dirt are easily washed away with a pressure washer, leaving the coating completely intact. As is popular with paint, polyurea coating can be dyed to match the preferred wall and floor color scheme in a facility.

What is the downside?

While there are many upsides to using polyurea coatings on wash bay surfaces, it is not the cheapest option. On average, 1/8inch polyurea coating in basic black costs about $2.50 per square foot for the material, not including the application labor. Thicker application coating and custom colors will increase the price.

Applying the coating is also not as easy as rolling paint on the walls. There are necessary personal safety equipment requirements including using a full breathing mask and a protective jump suit to be worn during application. Overspray on surrounding surfaces can also be a problem, so surrounding areas that are not being coated must be completely covered and sealed with plastic to protect them from overspray.

Overall, polyurea coatings are a good investment for your wash bays and other harsh maintenance environments because of the long lasting protection they give to the building surfaces and structure and the ease of cleaning. Polyurea coatings also are impervious to moisture and most chemical damage and can withstand both physical and environmental trauma. In addition, the ability to customize the color adds a professional touch that will last the life of the facility with limited upkeep or maintenance.

Mark Ellis, central region manager, and Justin Tripp, facility designer for Maintenance Design Group have worked with transit agencies throughout the U.S. to plan and design their bus maintenance facilities.
