General rules for fabric blind

Treat it dry for as long as possible, and use as little moisture as you can when you cannot.

Roller blinds in particular should be spot cleaned with a barely damp cloth and dried immediately, because the coating that keeps them flat is water sensitive. Roman blinds are lined and behave more like curtains.

Vertical blind slats can usually be unhooked and laid flat, which makes them far easier to treat than anything fixed.

Check the label

Roller blind fabric is usually stiffened with a resin or PVC coating so that it hangs flat and rolls straight. Wetting it dissolves or softens that stiffener, and the blind then ripples and stops rolling evenly. That is the specific risk here and it is not reversible.

Stains on fabric blind

A blind is fabric engineered to stay flat, and the engineering is what suffers.

Roller blinds are stiffened

The fabric is treated with a resin or PVC coating so it rolls straight. Water softens that coating, and the fabric dries wavy and no longer tracks properly on the roller. There is no repair.

Roman blinds are lined

So they behave like curtains: layers with different shrinkage, best spot cleaned in place.

Vertical slats come off

Unhooking the affected slats and laying them flat to treat them is easily the best option when it is available, and it lets you work on both sides.

Blackout coatings crack

A blackout blind has an opaque backing that cracks if it is folded or scrubbed, letting pinholes of light through afterwards.

  1. Why you cannot dry clean made to measure curtains, Britannia Rose manufacturer

    UK curtain maker's guidance that made to measure curtains combine face fabric, lining and often interlining with different compositions, that dry cleaning solvents can clean the layers unevenly and that even a small percentage of shrinkage significantly alters the drop, that pleats and stiffening can sag or harden, and that the recommended alternatives are vacuuming, spot cleaning with a diluted mild detergent tested first, and professional steam cleaning in situ.

    UK curtain and blind retailer guidance that its curtain fabrics are dry clean only, that machine washing risks the curtain and the lining shrinking at different rates and puckering, that up to 3 percent shrinkage can occur even in a first professional clean, that a small mark is spot cleaned by dabbing with warm water on a clean cloth and then diluted white vinegar tested on a hidden area first, and that water and steam are kept off the face of velvet curtains.

  3. Carpet tile maintenance guidelines, Interface manufacturer

    Carpet tile manufacturer's maintenance guidance: blot a spill with a clean white cloth working from the edge towards the centre, never rub a wet spill, keep a spotting solution between pH 4.5 and 8.5, avoid aggressive solvent based cleaners and optical brighteners, use as little water as possible because over wetting causes rapid resoiling and fibre damage, and replace a ruined tile from shelf stock.
