Choosing a carpet or upholstery cleaner

Match the method to the textile

Ask the contractor to check the care label and manufacturer requirements before proposing a method. CRI lists certified products, equipment and providers; Shaw gives product-specific care directions. Neither makes every method suitable for every carpet or establishes a universal method ranking.

Do not accept least-water or fastest-drying as a universal rule. Ask: compared with what, for which textile and on what evidence? The references used here provide no measured ranking of all methods.

Gather any manufacturer name, product details, purchase paperwork and upholstery care labels. If information is missing, say so rather than guessing, and ask how uncertainty affects the proposed work. For fabric codes, see caring for upholstered furniture.

Make the scope comparable

Ask for the agreed answers in writing. These are suggested purchasing questions, not a statement that all businesses use the same pricing system or provide the same assurances.

Use the same questions for every proposal. A missing answer is an open item, not proof of poor work: ask for clarification and keep the reply. To compare quantities and totals, see cleaning quotes and package scopes.

• Which rooms, stairs, furniture items and rugs are included?
• Which treatments or furniture moves would be extra, and when would you approve them?
• Which products and methods are proposed for the actual fibre and backing?
• What drying conditions, access and aftercare are required?
• How will an existing problem or accidental damage be recorded and handled?

Read product information

Ask to see the label and relevant safety information for a proposed treatment. CDC advises using products suitable for the surface, following instructions, providing ventilation and not mixing chemicals.

A term such as natural or green should not replace those checks. Do not treat a safety-data sheet alone as proof that a product is compatible with a particular textile.

Ask whether the label covers the proposed surface, how instructions and ventilation will be followed, and whether any products would be combined. Do not mix chemicals.

A safety sheet is not evidence of textile compatibility. Ask separately whether the textile manufacturer permits the proposed product. No product is endorsed here. For the distinction between the aims, see cleaning versus disinfecting.

A written contractor-question sheet

Copy one sheet per contractor. Record answers, date and whether they were written or spoken; leave unanswered items visibly open. This is a suggested purchasing record, not an industry standard.

• Header: business name, contact person, date of the conversation, and whether answers were given in writing.
• Identification: How will you identify the carpet or upholstery material, and what will you do if a care label is missing?
• Identification: Which manufacturer care instructions or warranty conditions did you check, and can you show me the passage?
• Method: Which method do you propose for each area (rooms, stairs, rugs, upholstery), and why that method for that material?
• Method: If you describe a method as using the least water or drying fastest, what is that compared with, and does it apply to my material?
• Method: Is any pre-treatment, spot treatment or deodorising step planned, and is it included or extra?
• Products: Can I see the label and relevant safety information for each product you propose to use?
• Products: Will any products be combined, and what ventilation will the room need?
• Scope: Which rooms, stairs, rugs and furniture items are included, and which are not?
• Scope: Which furniture will be moved, by whom, and what stays in place?
• Scope: What would count as an extra, and when would you ask me to approve it before doing it?
• Drying and access: What drying conditions, access, parking, and water and electricity use do you need, and what should I clear beforehand?
• Drying and access: What aftercare do you ask me to follow, and where is it written down?
• Existing problems: How will existing marks, wear, odours or past water damage be recorded before work starts?
• If an area does not respond: Will you stop and call me, try something else only with my approval, or leave the area as it is?
• Accidental damage: How is it reported and handled, and where is that written?
• Records: Will you give me a note of the areas cleaned, the method used and the products applied?

A worked comparison of material, method and scope

This fictional case illustrates reading proposals. The household, contractors and their statements are invented, not measured results or a ranking of methods.

Suppose a household wants a living-room carpet, a staircase and one upholstered armchair cleaned. The chair has a legible care label, but nobody can find the carpet's manufacturer or product name. Three contractors answer the sheet above.

Contractor 1 names a method and says it uses the least water and dries fastest. It gives a single total for living room, stairs and chair. Asked how the carpet is identified, it replies that its standard solution is used on all carpets. No product label or safety information is offered.

Contractor 2 names a different method and calls it gentler. Its quote is itemised by area, and moving furniture is listed as an extra. It offers to send product information later but does not say what happens if a mark fails to respond.

Contractor 3 names a method but says it will confirm it only after seeing the chair's care label and whatever the household can find about the carpet. Its written reply itemises the scope, states that any spot treatment beyond the marks listed would be quoted and approved before it is applied, and lists drying and access needs. It has not yet given a total.

Contractors 1 and 2 make comparative claims without a stated basis and leave carpet identification unclear. Contractor 3 gives more scope information but proves no cleaning result and has not quoted a total. Ask 1 for identification and product-label answers, 2 for identification and the non-response procedure, and 3 for a same-scope total. Also fill the remaining blank product, suitability and aftercare answers before choosing. More complete paperwork is not proof that a method cleans better.

When an area does not respond

Agree before work starts who may stop, whether additional treatment needs your approval and how the outcome will be recorded. These are suggested questions, not terms this site supplies for a contractor.

Record existing condition by location, date and plain description; do not diagnose an unverified cause. If photographs are used, agree how they are handled. Related reading includes the spot and stain chart, stain protection and trial cleans and demonstrations.

Accidental damage should be handled by a written route as well: whom to tell, how it is recorded and what remedy, if any, the business describes. This guide cannot say what a particular business will offer, and it is not legal advice. If something goes wrong, the notes you made before and after are the useful part.

Certifications, reviews and claims

If certification is claimed, ask which program and whether it covers a product, equipment or the provider, then check the claimed scope with the program. CRI lists these different categories; this guide has not checked any individual listing.

Reviews, testimonials and natural or green wording do not establish whether the proposed treatment suits your textile. Keep the material and scope questions separate; see reading cleaner reviews and testimonials.

None of this is a case against a particular kind of provider. The aim is to ask every provider the same questions and to prefer answers you can keep on paper.
