Which cleaning product belongs on which surface, and why? This guide explains how detergents work, how to care for common hard surfaces in a hotel, and where descalers fit in, so housekeeping trainees and supervisors can choose and use chemicals safely.
How detergents clean
A detergent is a cleaning agent that, used with water, loosens dirt and holds it in suspension so it can be rinsed away instead of settling back on the surface. A good detergent has three basic abilities:
- Wetting power: it lowers the surface tension of water so the water spreads over the surface and reaches the dirt.
- Emulsifying power: it breaks grease into tiny droplets so it can be lifted.
- Suspending power: it keeps the lifted dirt floating in the solution so it is not re-deposited.
These abilities come from surfactants. Each surfactant molecule has a water-loving head and a grease-loving tail. The tails attach to grease and oil, the heads stay in the water, and the dirt is carried away with the rinse.
What is inside a detergent
- Active ingredient: the surfactant. In soaps it comes from natural fats and oils; in synthetic detergents it is made from petrochemicals.
- Builders: compounds that do not clean by themselves but make the detergent work better, for example by softening water.
- Additives: items such as bleaching agents, brighteners, enzymes, perfume and dyes.
Types of detergents used in housekeeping
Soaps (soapy detergents)
Made by treating fats or oils with an alkali, a process called saponification. Soaps are cheap and gentle, but they work well only in soft water. In hard water they form a scum that is difficult to rinse. Toilet soaps, soap powders and soap flakes all belong here.
Synthetic detergents
These contain no soap and are not affected by hard water. By chemical nature they can be anionic, non-ionic, cationic or amphoteric. Common housekeeping forms include:
- Liquid synthetic detergents: light-duty, for hard surfaces and lightly soiled fabrics.
- Powdered synthetic detergents: heavy-duty, for heavily soiled laundry.
- Solvent-based detergents: for heavy grease in kitchens and on machinery, and for stripping some floor polishes.
- Biological detergents: contain enzymes that break down organic stains such as food and blood; they work best at moderate wash temperatures, not at boiling.
- Disinfectant detergents: usually based on quaternary ammonium compounds (“quats”); they clean and reduce germs in one step.
Strongly alkaline cleaners remove grease well but can harm skin and some finishes, so they need gloves and thorough rinsing.
Caring for hard surfaces in a hotel
Hotels have many hard surfaces: metals, glass, stone, ceramic tiles, wood, laminates and plastics. Each reacts differently to chemicals and to water, and damage is often permanent. Always identify the surface first, then choose the product.
| Surface | Care points |
|---|---|
| Marble and limestone | Sensitive to acids, which etch the surface. Use a neutral cleaner and avoid acidic descalers and toilet cleaners. |
| Granite and ceramic tiles | Neutral detergent and a clean mop. Rinse well to avoid a dull film. |
| Glass and mirrors | Glass cleaner with a lint-free cloth or squeegee. Avoid abrasives that scratch. |
| Stainless steel | Mild detergent, wipe along the grain, dry to avoid marks. Do not use scouring pads that scratch. |
| Brass and copper | Tarnish with time; use a suitable metal polish. See How to Clean and Maintain Brass and Copper. |
| Wood and laminate | Damp (not wet) cleaning, since excess water can swell or lift the surface. See The Right Way to Clean Laminate Flooring. |
| Plastics, leather and rubber | Mild detergent only; harsh solvents can crack or discolour them. |
Staff training matters here. A trainee who knows why marble and acid do not mix saves the hotel an expensive repair.
Descalers: removing limescale
Hard water leaves limescale (calcium and magnesium deposits) on kettles, taps, shower heads and toilets. Descalers are acid-based products that dissolve these deposits. The old TASKI R-series colour-coded range used in many hotels shows how this works in practice: R8 is a ready-to-use acid descaler for kettles, and R6 and R9 are for toilets and sanitary fittings. The manufacturer's guidance for kettle descaling is to fill and boil the kettle, let it cool slightly, add the product, leave it to work, rinse thoroughly with fresh water, and boil and discard one kettle of fresh water before use. Always follow the current product label and Safety Data Sheet. See also TASKI R6 and TASKI R9.
Safe chemical handling checklist
- Read the label and Safety Data Sheet before first use.
- Dilute exactly as the manufacturer says, using measured dispensers.
- Wear gloves, and eye protection for strong products.
- Never mix chemicals. Mixing a bleach-based product with an acid cleaner can release toxic gas.
- Keep products in their original, labelled containers.
- Rinse the surface and equipment well after use.
- Store in a dry, ventilated area, away from food.
- Wipe up spills immediately to prevent slips.
Choosing the right product: a quick method
- Identify the surface.
- Identify the soil: dust, grease, protein, limescale or stain.
- Pick the mildest product that works.
- Test on a hidden spot.
- Use the correct dilution and contact time, then rinse.

Frequently asked questions
What is the difference between soap and a synthetic detergent?
Soap is made from natural fats and oils and forms scum in hard water. A synthetic detergent is made from other raw materials and keeps working in hard water.
Why is hard water a problem in housekeeping?
It reduces the cleaning power of soap, leaves scale on fittings and appliances, and can leave films on surfaces.
Can I use the same cleaner on every surface?
No. Acidic products can damage marble, strong alkalis can harm some finishes, and abrasives scratch glass and steel. Match the product to the surface.
Why should chemicals never be mixed?
Some combinations produce harmful fumes or violent reactions. Use one product at a time and rinse between products.
How do I start a career in housekeeping?
Begin as a room attendant or trainee, learn products and procedures, and grow towards supervisor and executive housekeeper roles.
