Which is easier to clean-Wool or Synthetic?

I’m oftened asked which fibre to go for when purchasing a new carpet.
Having been cleaning carpets for over 30 years, I think it would be fair to say that I must have cleaned just about every carpet fibre out there. Putting aside vegetable fibres like linen, sisal and coir which need a specialist approach you are left with wool and the synthetic fibres. The two favourite synthetic fibres used in carpet manufacture are Nylon and polypropylene  with polypropylene now the most popular UK fibre used in house carpets.
Polypropylene is often promoted as easy-clean and stain proof. So how does wool compare with it?
That can be answered by understanding the differences between stain removal and maintenance and looking at each carpet fibre’s appearance over its lifecycle.
I think the most important issue for carpet owners is how their investment will respond to what modern living can throw at it.
Will it keep its appearance, or will it deteriorate prematurely?
This appearance is made up of a number of things, including loss of texture, thickness, colour and spots that won’t come out anymore.
All carpets have their strong and weak points.
Polypropylene carpets are pushed forward because of their stain resistance. They are almost impossible to stain with water-based materials because polypropylene does not absorb much water, however they don’t resist oily stains very well.
They also lack the resilience of wool and flatten relatively quickly. Although synthetic fibres start life with a shiny lustre, this soon dulls. This is because of the sandy and gritty components in soil, that come into the home on the soles of shoes, scratching the fibre. Imagine dragging sand paper over a plastic surface and you’ll get the idea.
On the other hand, wool carpets are well-known for their long lasting appearance, this is based on their excellent ability to bounce back, a great response to both dry and wet cleaning, good resistance to soiling and retention of colour. Staining, can be a problem, but only if left to soak into the fibres. If spillages are promptly attended to then there is rarely a problem. Wool carpets justifiably have a great reputation for longevity that other carpets lack.
Synthetic fibres, will initially respond well to cleaning but over time they don’t clean so easily. This is because the fibres get damaged, with little cracks and fissures developing in each fibre, trapping dirt and spills which become almost impossible to get out again. These carpets don’t age with the same charm as wool.
Correctly cleaned, wool carpets can be easily maintained to their highest level of appearance and that’s why, despite costing slightly more, they are still chosen where appearance is of the greatest importance
