Trial cleans and demonstrations: what to agree and record

Agree the terms before work starts

Ask whether the trial is free or charged, how large an area it covers and whether you are under any obligation afterwards. Ask whether there is any charge if you decide not to proceed.

Ask which method and product will be used, and ask to see the product label before it is applied.

These are questions about the trial itself, and they are worth settling before anyone opens a bottle or moves furniture. An informal offer of a trial can mean quite different things, for example a short demonstration on a small patch, the first part of a paid job, or a sales visit that also produces a quote. Writing the answers down, even as a short message confirming what was said, gives both sides the same description of what the trial is and what it is not.

Choose the test area with care

Check that the textile manufacturer permits the proposed method on that carpet or rug. CRI advises pretesting an appropriate cleaner and following its directions; Shaw gives product-specific care directions for its carpets.

A result on one area does not show that the same method suits a wool or silk rug, a valuable item, upholstery or a different carpet in another room. Each material needs its own check.

Record the condition before and after

A simple record makes the trial useful for comparison. Without one, the comparison depends on your recollection of how the patch looked beforehand.

• Photograph the area from the same position and in similar light before and after.
• Note existing marks, wear, colour differences and odour before any work begins.
• Write down which product and method were used, and how much moisture the area was left with.
• Ask for drying and return-to-use instructions for the area.
• Judge the result after the area has dried according to those instructions, rather than immediately.

Before the contractor arrives

A few preparations make the trial easier to interpret. Check the textile manufacturer's permission and the actual product label before the trial; the preparation suggestions below help keep that information together.

• Find the manufacturer's care leaflet, label or purchase paperwork for the carpet or rug and note the material. If it cannot be identified, record it as unknown and say so to the contractor.
• Ask the contractor to name the method proposed for that material and the basis on which it is permitted. A vague answer is itself useful information.
• Describe the trial area in plain words, such as 'the section of carpet between the sofa and the window', so both sides mean the same patch.
• Decide who will take photographs, and from where, before work starts.
• Ask for the estimate to be sent separately after the trial, rather than discussed and accepted at the visit.

A before-and-after observation sheet

The sheet below turns the record-keeping advice into fields you can copy into a notebook or a message to yourself. It records what was agreed and what you saw; it does not score the contractor.

• Date, time and who attended; the item or room.
• Agreed scope: the trial area in plain words, what is excluded, whether the trial is free or charged, and any obligation afterwards.
• Material: as identified from manufacturer documents or a label, or 'unknown'.
• Product and method: the product name as printed on the label, the method as the contractor described it, and whether the label was seen before application.
• Lighting and position: where the photographer stood, camera height, which windows and lights were on, and the time of day, repeated for the 'after' photograph.
• Before: photographs taken, existing marks, wear, colour differences and odour.
• Moisture: how damp the area was left.
• Drying and return-to-use instructions: copied as given, with who gave them.
• Judgement time: when the area had dried according to those instructions, and the second photograph taken then.
• Observations after drying: what changed, what did not, any new concern.
• Not shown by this trial: a standing line recording that this is one patch on one day.
• Estimate: received separately in writing, yes or no, and the date.

A hypothetical completed sheet

The entries below are invented. They do not describe a real demonstration, a real contractor or a real result, and they are not evidence that any method works. They exist only to show what completed fields could look like.

Date and attendees: a weekday morning; the householder and one technician. Item: a living-room carpet, one patch between the sofa and the window. Agreed scope: that patch only, confirmed in a short message beforehand; free; no obligation afterwards; no charge if the householder decides not to proceed; the wider job is not included. Material: copied from the manufacturer's care leaflet.

Product and method: product name copied from the label, which was shown before application; method noted in the technician's own words. Lighting and position: photographed from the doorway at standing height, curtains open, ceiling light on, same settings afterwards. Before: one faint mark near the edge of the patch, slightly lighter colour toward the window, no noticeable odour.

Moisture: damp to the touch at the end of the work. Drying and return-to-use instructions: copied exactly from the technician's written note. Judgement time: after the area has dried in accordance with the relevant instructions, not merely when an estimated drying period has elapsed. Observations: the faint mark looks lighter in the second photograph; the colour variation near the window looks unchanged; the edge of the carpet was not part of the patch. Estimate: to be sent separately, not discussed at the visit, decision deferred until it has been compared.

Notice what the invented sheet does not conclude. It does not say the whole room would turn out the same, that stairs and edges would be treated consistently, that other marks would respond, that the result would look the same later, or that the method would suit another material or a later treatment. The standing line at the bottom of the sheet is there to stop a good-looking patch from being read as more than it is.

What a demonstration cannot show

A trial area shows one patch on one day. It cannot show how consistently a whole room, stairs and edges will be treated, how different marks elsewhere will respond or how the result will look later.

Treat a good trial as one piece of information, not as a guarantee of the full job.

The same limit applies to materials and to anything you might add later. A patch on one carpet says little about a wool or silk rug, upholstery or a carpet in another room, and it says nothing about how a method sits alongside a later treatment. That is a separate topic; the guide on questions to ask before a stain-protection treatment is worth reading before agreeing to one.

What the estimate must still say

Ask for a written, itemised estimate separate from the trial, covering rooms, stairs, furniture, add-ons, drying, how an area that does not respond will be handled and how accidental damage will be dealt with. The guide to comparing cleaning quotes and package scopes shows how to itemise it.

If you feel pressed to decide on the spot, it is reasonable to take the estimate away and compare it with others first.

Any product used should be suitable for the surface and applied according to its label with ventilation, as CDC advises, and products should never be mixed.

Deciding after the trial

Once the area has dried and the second photograph is taken, the sheet has done its job: it gives you a record to set beside the estimate. A useful test is to ask whether the estimate would read the same if the trial had never happened. If it leans on the trial ('as you saw today'), ask for the specifics to be written into the document.

You then have a handful of reasonable options: proceed on the written estimate; proceed with a changed scope; ask for a second trial on a different patch or material; or decline. Check what was agreed about charges before choosing the last option. If you want a second view on the contractor, reading reviews and testimonials explains what such accounts can and cannot tell you, and the guide to choosing a carpet or upholstery cleaner covers the wider decision. If a particular mark is the reason for the trial, the carpet spot and stain chart is a related reference.
