Understand the risk of colour change
Some bleach products can remove carpet dye or affect fibres, backing and adhesives. A patch test cannot guarantee that a product will not change the colour elsewhere or later. Do not follow advice to feather bleach across a carpet to hide a transition.
Check both the carpet and product instructions
Read the carpet/rug care label and the exact cleaner label. Use a product only if its label and the carpet maker both permit the intended surface and task. Do not guess a dilution, use another brand’s recipe or mix bleach with another cleaning chemical.
Choose a compatible carpet product for removable soil
If the issue is ordinary soil rather than colour loss, use a product specifically permitted for the carpet and follow its complete directions. Check machine instructions if using equipment. A stain or faded mark may be material damage rather than removable soil.
If bleach has already contacted the carpet
Stop before adding another chemical or trying to neutralize it. Note the product name, amount and time, and check its label and carpet-care guidance. Contact the carpet maker or a qualified carpet-care provider if colour or texture has changed.
