Why does all-purpose cleaner need different dilutions for different jobs?

Concentration controls how aggressive an all-purpose cleaner is. A strong dilution may be suitable for heavily soiled tires or engine bays, while interior plastics and leather need a much weaker one. Using too strong a mix can discolor, dry out or leave residue on delicate surfaces, and using too weak a mix wastes time. Follow the label's dilution table and measure rather than guessing.
