Which would damage the wool fibres more high temp, high ph or aggressive aggatation
It's ok to say high heat would damage the fibres but if you use low heat but Have to compensate by scrubbing it harder would that cause more damage? Or use a stronger cleaning chemical, does that cause more damage than heat?
And........ If you are having to consider these alternatives is it too late, the carpet has already been damaged by allowing the carpet to get too soiled so we are not cleaning the carpet but trying to rescue it
