Old spots are virtually impossible to remove - seek assistance from cleaning firm.
Every wool fibre naturally has its own thin, protective layer. This allows wool to repel dirt and gives you the opportunity to act when anything is spilled on the carpet. Naturally, all spots should be treated as soon as possible. Below are some useful tips.
Always remove the spot immediately.
Scrape off as much of the spilled moisture or substance with a spoon or a knife where possible, working from the edge towards the centre of the spot.
Clean the spot with a cloth or absorbing paper. Do not rub or scrub, just dab!
Do not make the spot too wet.
When using a detergent, always remove it from the pile using water (when using detergents or a solvent, always try it out in an inconspicuous place first).
Dry the carpet thoroughly after removing the spot, using a hairdryer.
