How steamships managed coal soot on their sails

Did coal smoke foul the sails of ships that combined steam and sail?

Yes, but sails were furled when steaming so smoke could escape, and crews could clean the soot afterward.

Funnel smoke deposited soot on the rig of ships that combined steam and sail. When steaming, the sails were normally furled so exhaust could rise without a full spread of canvas in its path. The cloth could still become dirty, but routine cleaning dealt with the residue. Hybrid operation created extra maintenance without making the sailing rig unusable.
