How do I clean tear stains without irritating the skin?

Tear stains build up gradually, so trying to remove weeks of staining in one aggressive session tends to irritate the already sensitive skin underneath without actually achieving a better result than consistent daily cleaning would have. A light daily wipe prevents the stain from ever setting in as deeply.

Dab rather than rub, using a soft cloth or cotton pad dampened with warm water, working from the inner corner outward. Pat the area dry afterward with a clean section of cloth, since leaving the fur consistently damp can itself contribute to skin irritation underneath the staining.

Keeping the fur trimmed short under the eyes reduces the surface area holding moisture against the skin, and switching to filtered water for drinking, since minerals in some tap water are thought to worsen staining in sensitive dogs, are both reasonable additions to a gentle daily cleaning routine.

Even with perfectly gentle daily cleaning, existing staining already set into the fur will not disappear overnight, since it fades only as new, clean fur grows in to replace it, a process that typically takes several weeks depending on how fast your dog's coat grows in that area, so patience matters as much as technique.

Switching your dog to a stainless steel or ceramic water bowl, if not already using one, alongside your cleaning routine, removes another potential source of bacteria that some owners find contributes to staining around the whole face area.
