A buyer who has decided that cleaning commercial sink exteriors needs machine help usually sends a short request: “we need a steam machine for sinks.” That sentence is not enough for a manufacturer to quote the right equipment. Before the first RFQ goes out, write a brief that answers four questions: where the sinks are, what the surface is, what the soil is, and what the site can supply.
Start with the room, not the machine
The location decides the form factor. A floor-standing sink in a central kitchen, a row of hand-washing sinks in a canteen servery, and stainless steel sink units next to a production line each put the equipment in a different class. In the brief, state whether the cleaning happens in a wet room with a floor drain, a dry area where water run-off is a problem, or a space that staff must keep open during the shift. Steam-based cleaning uses far less water than a hose, which matters when there is no drain nearby, but the room still has to tolerate moisture and heat.
Also record how far the operator walks. Fixed machines stay in one place and need plumbing and power at that point. Mobile and hand-pushed units move between sinks, so the brief should list aisle widths, door thresholds, steps, and whether the floor is non-slip once wet. A machine that cannot reach the sink is useless regardless of its output.
Describe the sink: material, construction, and attachments
Write down what the exteriors are made of and how they are built. Stainless steel sinks dominate food and institutional settings, and the grade and finish affect how visible grease and water marks are after cleaning. Note whether the exterior is a flat panel, a boxed cabinet, or an open frame with legs, because open frames have more edges, brackets and weld seams that collect deposits. List the parts buyers always forget in the brief: tap bodies, splashbacks, undershelf brackets, drain surrounds, the gap between the sink and the wall, and any pipework running under the sink.
Give the working height and whether the base is reachable. A sink on legs with a sealed base panel needs a different nozzle and lance set than a wall-hung unit where the floor under it is clear. If the site has sinks of different heights, say so, since it affects how the operator holds the wand for a full shift.
Name the soil, not just the task
“Dirty” is not a specification. Say what is actually on the exterior: cooking oil and grease that has polymerised into a sticky film, sugar syrup from beverage preparation, starch, protein residue, dust from storage, or scale from hard water around tap fittings. Grease that has been heated and re-heated behaves completely differently from fresh splashes, and it usually needs higher temperature rather than more pressure. Scale and mineral deposits need their own treatment plan, so flag them in the brief and ask the supplier how they should be handled.
If the sinks sit in a food area, say whether surfaces must be brought to a hygienic standard after cleaning, and whether the site runs its own verification such as visual inspection, swab checks, or an outside hygiene audit. That tells the manufacturer whether the job is cleaning alone or cleaning plus disinfection, which changes the equipment and the workflow.
State the utilities and access the site can actually provide
This is the section most briefs leave blank, and it is where quotations go wrong. For each candidate location, list the available electrical supply, including voltage and whether the circuit is shared with cooking or refrigeration equipment. Note whether hot water is available at the sink, and how far the machine has to be from a water source. For battery-powered or mobile units, record where they can be charged and by whom, since charging space in a busy kitchen is rarely free.
Add the practical constraints: noise limits if cleaning happens while the room is in use, working hours the cleaning window falls in, and whether the equipment must be out of sight between uses. State who will operate the machine and how many shifts, because a unit specified for one trained technician is a different machine from one used by rotating kitchen staff.
Equipment questions to put in the RFQ
With the site data in hand, ask the supplier targeted questions rather than comparing brochures. Can the machine switch between dry steam for light surface work and wetter steam for heavier deposits? What is the water tank capacity between refills, and is the tank material suitable for the site’s water? Is the machine built for daily commercial use, and what protection is fitted against leakage, short circuit, high temperature and water shortage? What accessories come with it, and which nozzle or brush is intended for flat panels versus seams and edges?
Ask how the unit is serviced, which parts wear out, and how quickly replacements ship. Then ask the supplier to state clearly which sink surfaces and soil types their equipment is intended for. A manufacturer who answers that question precisely is worth more than one with a longer product list.
How PowerDe fits into this process
Shenzhen PowerDe Automation Precision Equipment Co., Ltd. builds commercial steam cleaning equipment in several configurations: fixed machines such as the PowerDe HW02, hand-pushed units, and driving-style mobile machines. The fixed models connect to a site supply and suit a defined cleaning point; the hand-pushed and mobile units are intended for operators covering several locations. Published parameter sheets for these models describe tank capacity, heating power and steam settings, along with the dry-steam and wet-steam modes that let one operator move between light and heavy work.
Send the finished brief to PowerDe with the site drawings or photographs attached, and ask the team to match the machine and accessories to the room and the soil. Where a standard model does not fit, PowerDe offers customized steam cleaning equipment, so the brief is also the basis for a built-to-order solution.
A short checklist to attach to the brief
- Number and type of sinks, and whether they are free-standing, wall-hung or built into a counter
- Exterior construction: flat panel, cabinet, open frame, plus pipework, brackets and drain surrounds
- Soil type, with the worst case described in plain words (burnt-on grease, syrup, scale)
- Room conditions: floor drain or no drain, ventilation, noise limits, cleaning window
- Available power supply and hot water; charging location for mobile units
- Travel route between sinks: distances, thresholds, steps, floor surface when wet
- Hygiene standard required and how the site verifies it
- Who operates the machine, on how many shifts, and what training the site can support
A brief built on this list lets a supplier respond with a specific model, the right accessories and a realistic service plan. It also protects the buyer: everyone is quoting the same job.
