This can result from inadequate water filling the tub, partially clogge spray arms, water that isn't hot enough, old detergent or etching.

Etching is the progreesive wear on glasses from the abrasive in detergents. Etching is in the glass and cannot be removed.

The other possibilities can be caused by a faulty water valve, spray arms that won't spin or have material inside, a malfunctioning water heating cycle or old/low quality detergent - respectively.
