The WoolSafe Approved mark on a bottle means that exact product has been independently tested and found safe to use on wool. It says nothing about the company that sells it or the person using it, and it only covers that one formulation, not every product the brand makes. So the useful habit is simple: look for the mark on the specific bottle, then use it at the dilution the label gives.
This guide explains what the mark tests, the related marks you will see beside it, which professional products carried it when we wrote this, and how to use an approved product without undoing the point of buying one.
What the mark tests
A product is not approved for cleaning well. It is approved for what it does to wool, which is a harder test to pass. The assessment looks at:
- The pH of the product as you use it, diluted, rather than the concentrate in the bottle. Wool is only comfortable close to neutral, and alkaline products open its scales and loosen its dyes. Our guide to pH in carpet cleaning explains why one number decides so much.
- Colourfastness, whether the dyes stay put.
- Fibre strength and feel, whether the wool is weakened or roughened.
- Residue, whether it rinses out and whether what remains attracts soil, which is the reason a carpet can look worse a month after cleaning than before.
The marks you will see
- WoolSafe Approved: tested for use on wool. The mark that matters most for a wool carpet or rug.
- CleanSeal Approved: tested for use on synthetic fibres such as nylon, polyester and polypropylene. See what CleanSeal is.
- Green WoolSafe and EnviroSeal: the product has also met environmental requirements, on top of performance and safety.
Many professional products carry both WoolSafe and CleanSeal, which is what you want in a house with a wool rug on a synthetic carpet: one product that is safe on the first and performs on the second.
Professional products on the approved list
For stain removal and general care we recommend the Prochem range, and for encapsulation we recommend Environ HP and Kärcher’s RM range. When we checked the WoolSafe Organisation’s list of approved professional products in September 2026, it included these, each listed with both the WoolSafe and CleanSeal marks:
- Prochem pre-treatments: B107 Prespray Gold and E717 Natural Carpet Prespray.
- Prochem extraction solutions: S780 Fibersafe Gold, S781 Liquid Woolsafe, B106 Extraclean and E772 Natural Carpet Cleaner.
- Prochem rinses and post-treatments:B109 Fibre & Fabric Rinse and B112 Neutra-Soft.
- Prochem low moisture: C803 / C812 Fiberdri and S745 Procaps.
- Kärcher CarpetPro (RM range): RM 768 iCapsol for low moisture and encapsulation cleaning, RM 764 and RM 760 for extraction, and RM 763 Conditioner.
Two cautions. The list changes, so check the mark on the bottle you are actually buying rather than trusting this article, and do not assume a product is approved because others from the same brand are. Prochem in particular is a full professional range covering the whole pH scale, and plenty of its products are made for jobs that have nothing to do with wool. Choose from the approved ones for a wool piece.
Where to buy them in South Africa
These are trade products, sold through professional cleaning suppliers rather than supermarkets. At the time of writing, the WoolSafe Organisation’s list of approved consumer products did not flag any as available in South Africa, so a supermarket carpet cleaner here is very unlikely to carry the mark. Buying from a trade supplier is a small extra effort and worth it, because the trade products state their pH, come with proper dilution ratios and publish safety data sheets, which is exactly what a consumer bottle tends to leave out.
Why professional products come as concentrates
Most approved professional products are sold concentrated, to be diluted with water before use. That can feel like a nuisance, but it is the point. The approval is tested at the dilution printed on the label, and the label gives a different ratio for different jobs, a stronger mix for a heavily soiled spot and a weaker one for general cleaning. A ready-to-use consumer bottle hides that choice from you and rarely states the pH at all. Measure the concentrate rather than pouring by eye, mix only what you need for the job, and label any bottle you mix into, so a wool-safe solution is never confused with something else under the sink.
How to use an approved product properly
- Dilute exactly as the label says. Approval is tested at the stated dilution. Stronger is not safer, and on wool it can undo the whole point.
- Test first. Try it on a hidden corner and check each colour with a white cloth before using it on the rug.
- Blot, never scrub. Scrubbing wool while it is wet is what causes felting.
- Rinse and dry quickly. A little clean water, blotted out, then airflow.
- Know the fibres it cannot save. Approval for wool is not approval for viscose, which is damaged by water itself, whatever product is in it. See why viscose must never be wet cleaned.

Why ordinary products go wrong on wool
The reason the mark exists is that many products sold for carpet were designed with synthetics in mind, where the chemistry has a lot of room for error. On wool, four ingredients cause most of the trouble:
- High alkalinity, common in general-purpose shampoos and degreasers. It opens the wool’s scales, dulls the pile and loosens dyes.
- Oxygen bleach, the active part of most “oxy” spot removers. It lightens wool dye permanently and leaves a pale patch with a clean edge.
- Protein-digesting enzymes, excellent on synthetic carpet for food and pet stains, but wool is a protein, so the enzyme works on the fibre as well as the stain.
- Optical brighteners, which make a pile look whiter for a while and cannot be removed from a natural fibre afterwards.
An approved product has been tested against exactly these problems, which is why it is the simplest protection a wool rug owner has. Our list of products that damage carpet and rugs goes further.
A small kit for a wool rug at home
You do not need much to deal with the everyday spill, and having it ready matters more than having a lot of it:
- A stack of plain white cloths or paper towel, so you can see what is lifting.
- One WoolSafe Approved spotter, diluted as the label says and kept in a labelled bottle.
- A spray bottle of clean, cool water for rinsing.
- A fan, or a window you can open, to dry the spot quickly.
Blot the spill first, treat it with the spotter, blot again, mist with clean water and blot once more, then dry it with airflow. If the mark has not moved after one careful attempt, stop there. A second or third product on the same spot is how a small stain becomes a permanent one.
What we use
As a WoolSafe & CleanSeal Approved Service Provider, we have committed in writing to using approved products on every wool and wool-rich carpet or rug we clean, and approved products when we clean synthetics. That commitment is part of what our registration covers, and it is checked every year when it is renewed.
Common questions
What does WoolSafe Approved mean on a cleaning product?
It means that specific product has been independently tested for use on wool: its pH as used, its effect on colourfastness and fibre strength, whether it rinses out cleanly, and whether its residue attracts soil. It certifies the product, not the company selling or using it, and it applies to that formulation only, not to everything the brand makes.
Which carpet cleaning products are WoolSafe approved?
The WoolSafe Organisation publishes the current list. In September 2026 it included professional products such as Prochem’s B107 Prespray Gold, S780 Fibersafe Gold, S781 Liquid Woolsafe and B109 Fibre & Fabric Rinse, and Kärcher’s CarpetPro RM 768 iCapsol and RM 764. The list changes, so always check for the mark on the specific bottle.
Can I buy WoolSafe approved products in South Africa?
Yes, through professional cleaning suppliers rather than supermarkets. The approved products are mainly trade ranges, and at the time of writing the approved consumer products list did not flag any as available in South Africa. Trade products also state their pH and dilution and publish safety data sheets, which is worth the extra effort on a wool rug.
Is a WoolSafe approved product safe on every rug?
No. It is tested for wool. It still needs to be used at the right dilution and tested on each colour first, and it does not make water safe for a viscose or art silk rug, which is damaged by moisture itself and has to be dry cleaned.
