The pH of a cleaning solution is a measure of its acidity or basicity, with a pH of 7 being neutral. Wool, like most natural fibers, is sensitive to pH and can be damaged by solutions that are too acidic or alkaline.
For wool fibers, it is generally recommended to use a cleaning solution with a pH between 6 and 8. This range is considered to be mildly acidic to neutral, and it is gentle enough to not cause damage to the wool fibers.
There are a number of cleaning solutions that are specifically formulated for use on wool fibers, and these solutions typically have a pH within the recommended range. Some examples include wool-specific detergents, wool-specific shampoos, and wool-specific spot cleaners.
It's important to follow the manufacturer's instructions when using any cleaning solution on wool fibers, and to test a small, inconspicuous area first to make sure the solution does not cause any damage. If you are unsure about the pH of a particular cleaning solution, you can test it with a pH strip or a pH meter to determine its acidity or basicity.
In general, it is always best to use the mildest cleaning solution that is effective for the specific stain or soil you are trying to remove. This will help to minimize the risk of damage to the wool fibers and prolong the life of your wool carpet or upholstery.
