Upholstery shampoo?

[beadyboo]

I have a couple of these armchairs from ikea. They are starting to look a bit grubby on the armrests and edge of seat cushion.
The cleaning instructions say use upholstery shampoo, but also do not wash. The fabric isn't removable.
Can anyone recommend a product and method of cleaning, or is my only option to get the professionals in? Thanks.

Original Stardrops in a bit of warm water. Dunk a cloth in it - an old cotton or linen tea towel is perfect - wring it out until barely damp then use a circular motion to clean the chair. Stop regularly and rinse and wring the cloth out.

I did this with a grubby sofa and it gave it a new lease of life.

Stardrops are also great for carpet cleaning.
