Upholstery fabric

Carpet advice does not transfer to it. The manufacturer's rules start with what NOT to vacuum with, and water is on the prohibited list rather than the method list.

What not to do

Water is unsafe on Upholstery fabric

Unsafe

Do not do this. The risk is established, and it is described below.

For panel and workspace cloth specifically. Not every sofa fabric — but the assumption that water is always the gentle option fails here.

Precautions

  • Test on an inconspicuous area first
  • Check the manufacturer's instructions

For the WS code, the most permissive of the three that allow liquid at all. If steam is not recommended where both water and solvent are allowed, it is not a default for upholstery.

Machine washing should be avoided for Upholstery fabric

Best avoided

The available guidance advises against this.

Aimed at the thing people actually do: unzip the cushion cover and put it through the wash. Every code that permits liquid at all says not to.

In detail

Upholstery looks like carpet on a vertical surface and is not treated like it. The manufacturer's normal-cleaning instruction is to vacuum with an UPHOLSTERY ATTACHMENT and explicitly not to brush the fabric or use an attachment with a ROTARY BRUSH, because brushing may permanently damage the nap or change the character of the fabric — the same prohibition the leather trade gives, for the same reason, on a different material. For panel and workspace fabrics the restrictions go further than anything in the carpet guidance: do not apply water or any liquid solution, because wetting the fabric may result in permanent damage, and do not use steam. Where more is needed the route is dry cleaning or a solvent spot cleaner, and on a wool blend a dry-cleaning solution on a damp cloth is directed for BOTH water-based and oil-based stains. One spot-cleaning instruction inverts the usual advice and is worth carrying: soak the stain up immediately, and do not let it dry completely or it may set. With most spills on most surfaces drying is the safe default; on this fabric it is the thing to avoid.

What works

    Vacuum cleaner is safe on, in specific conditions, Upholstery fabric

    Safe only in specific conditions

    This is only appropriate within specific limits. Outside those limits, no claim is made.

    Only within these limits:

    • Upholstery attachment only — NOT an attachment with a rotary brush
    • Do not brush the fabric
    • Do not apply water or any liquid solution to panel and workspace fabrics; wetting may cause permanent damage
    • Do not use steam

    Where more than vacuuming is needed the route is dry cleaning or spot cleaning with a solvent cleaner, not water.

    Precautions

    • Test on an inconspicuous area first

    Upholstery attachment is safe on, in specific conditions, Upholstery fabric

    Safe only in specific conditions

    This is only appropriate within specific limits. Outside those limits, no claim is made.

    Only within these limits:

    • Frequent vacuuming, or light brushing with a NON-METALLIC soft-bristle brush
    • No rotary-brush attachment — brushing can permanently change the nap
    • This is the routine under every code, including X, where nothing wet is allowed at all

    The only instruction the upholstery standard gives without exception across all four cleaning codes, which makes it the one thing that is right before the code is known.

    Dry soil removal is safe on, in specific conditions, Upholstery fabric

    Safe only in specific conditions

    This is only appropriate within specific limits. Outside those limits, no claim is made.

    Only within these limits:

    • Vacuum frequently, or brush lightly with a NON-METALLIC soft-bristle brush
    • No rotary or beater-bar attachment — brushing can permanently change the nap
    • This is the routine under every cleaning code, including X, where nothing wet is permitted at all

    The only instruction the upholstery standard gives without exception across all four codes, which makes it the one step that is right before the code has been read.

    Blotting is safe on, in specific conditions, Upholstery fabric

    Safe only in specific conditions

    This is only appropriate within specific limits. Outside those limits, no claim is made.

    Only within these limits:

    • Blot immediately — do not rub, and do not scrub
    • Apply any solution to the CLOTH, never to the fabric
    • Work from the edge of the mark inwards, so the mark does not spread
    • Do not over wet; on an S-coded fabric do not use water at all

    The upholstery standard's own instruction goes further than most readers expect: after blotting the spill, clean the ENTIRE PANEL seam to seam rather than the spot, or the result is a clean patch on a dirty arm.

    Precautions

    • Test on an inconspicuous area first
