StainOut 71-502 Big Mouth 5 Qt Injection Sprayer + Shazaam Kryptonium Cleaner Bundle 20240224
Professional rear-fill injection sprayer plus 1 gallon of Shazaam Kryptonium cleaner. This Steam-Brite package combines the heavy-duty StainOut Systems 71-502 Big Mouth Injection Sprayer with 1 gallon of Shazaam SBM230 Kryptonium High-pH Degreaser.
The StainOut 71-502 is built around a thick-wall rotomolded 5-quart bottle rather than the thin blow-molded bottles commonly found on lower-cost injection sprayers. For professional cleaners who use their equipment every day, that difference can dramatically improve durability and long-term value.

Why Buy a Rotomolded Injection Sprayer?
Not all injection sprayer bottles are built the same. Many inexpensive injection sprayers use thin-wall blow-molded bottles. These bottles cost less to manufacture but are more susceptible to cracking, splitting, and fatigue from everyday commercial use.
Professional cleaners commonly find that inexpensive blow-molded sprayer bottles may require replacement after relatively short periods of daily service. In many applications, approximately a year of hard commercial use can be enough to expose weaknesses around the neck, bottom, fittings, or other high-stress areas.
The StainOut 71-502 instead uses a heavy-duty rotomolded polyethylene bottle. Rotomolding produces substantially thicker walls and a much more rigid, impact-resistant container.
Many professional users find that the thick-wall rotomolded bottle lasts for many years and can effectively last the working lifetime of the sprayer. In normal professional service, the bottle may never need to be replaced.
Rotomolded Bottle Advantages
- Much thicker walls than typical blow-molded bottles
- Excellent impact resistance
- Better resistance to cracking around fittings and the bottle neck
- Designed to withstand daily van and truckmount use
- More resistant to drops, vibration, and rough handling
- Wide, stable base helps prevent tipping
- Long service life can reduce future replacement costs
- For many users, the bottle may last the lifetime of the sprayer
Buy the sprayer for long-term service instead of repeatedly replacing inexpensive bottles. For a professional cleaner, the initial purchase price is only one part of the true cost of ownership.
The History Behind This Injection Sprayer
The design behind this professional inline injection sprayer has roots going back to 1981.
Steam-Brite founder Donald Cook developed the original injection sprayer concept in 1981 as a faster and more practical method for professional carpet cleaners to apply prespray chemicals. Instead of repeatedly pumping and refilling conventional pump-up sprayers, pressurized cleaning solution could be used to automatically draw and mix concentrated chemical while spraying.
The concept continued to evolve over the following decades and eventually became a familiar tool throughout the professional carpet cleaning industry.
Many experienced cleaners will also recognize the design from the Mytee injection sprayers sold for many years. After Mytee changed ownership, the next generation of the LaBarbera family established StainOut Systems and continued offering this familiar professional injection sprayer design under the StainOut name.
The current StainOut 71-502 Big Mouth Injection Sprayer carries that design forward with modern features including a heavy-duty rotomolded bottle, large rear fill opening, stainless-steel components, Viton seals, improved filtration, and high-pressure capability.
Steam-Brite therefore offers more than simply another injection sprayer. We have decades of real-world experience with this equipment and can provide practical maintenance, troubleshooting, replacement parts, and operating advice.
Why Professionals Choose the StainOut 71-502
- 5-quart chemical capacity
- Heavy-duty rotomolded bottle
- Large rear Big Mouth fill port
- 30 to 1000 PSI operating range
- Works with many professional truckmounts and portable extractors
- Stainless-steel components
- Viton chemical-resistant seals
- Anti-drip spray jet
- 8006 brass TeeJet spray tip
- Brass and stainless suction strainer
- 7-inch comfort foam grip
- 2-inch bottle retaining strap
- Translucent bottle makes chemical level easy to monitor
- Wide base helps resist tipping in vans and on the jobsite
Big Mouth Rear Fill Design
One of the most useful features of the StainOut 71-502 is the large rear fill opening.
Instead of removing the complete sprayer assembly every time additional chemical is needed, the operator can open the rear fill port and quickly add solution while leaving the gun and injector assembly in place.
The large opening also makes the bottle easier to rinse, clean, and maintain between jobs.
How an Inline Injection Sprayer Works
The StainOut 71-502 connects to the high-pressure solution hose of a compatible professional carpet extractor or truckmount.
As pressurized water passes through the injector, concentrated cleaning chemical is drawn from the 5-quart bottle and automatically mixed into the flowing water before being sprayed onto the surface.
This allows a professional cleaner to apply large quantities of prespray without repeatedly stopping to pump a conventional hand sprayer.
Approximate Injection Ratios
| Configuration |
Approximate Injection Ratio |
| Yellow metering tip at approximately 250 PSI and higher |
Approximately 1:8 |
| No metering tip |
Approximately 1:4 |
| Approximately 250 PSI and lower without metering tip |
Approximately 1:4 |
Injection ratios are approximate. Actual dilution can vary depending on water pressure, temperature, chemical viscosity, metering tip, hose configuration, injector condition, and other operating variables.
Shazaam Kryptonium Cleaner Included

Watch: Injection Sprayer Maintenance & Repair
One advantage of purchasing professional serviceable equipment is that routine maintenance can keep it working for many years. In this Steam-Brite training video, Donald Cook demonstrates injection sprayer maintenance and troubleshooting techniques based on decades of experience with this equipment.
The video can help with:
- Routine injection sprayer maintenance
- Cleaning clogged components
- Inspecting the injector and solution pickup system
- Cleaning strainers and spray components
- Troubleshooting a sprayer that stops drawing chemical
- Extending the service life of seals, fittings, and internal parts
Steam-Brite Maintenance Tip: Flush the injection sprayer with clean water after using presprays, degreasers, or specialty chemicals. Routine flushing helps prevent dried chemical buildup, clogged injectors, restricted strainers, and unnecessary seal wear.
