In that case, it might be corrosion or coffee stain. Try soak it with Caffiza solution and if still got stains, it’s corrosion. Actually coffee is slightly acid.

Bleach? Not great for metal.
Don’t you have Puly or cafiza ?

Oxidization in aluminium. Cafiza will probably turn the whole portafilter matte gray. Best way to clean is by using the coarse side of dish sponge and sand away the stains.
