How To Clean A Canister Filter Insides?

I recently bought a canister filter from someone and they used it in a brackish tank. when I got the filter home it has caked on brown stuff inside it

the model is sunsun HW 303b.

I want to use it in a freshwater tank but i'm worried about residue that might mess with something.

is there a way to clean the insides by the the impeller and uv bulb without taking it apart? (I know how to take the top off and clean pads but i'm worried if I start undoing screws I might never get it back together)

we have the hw304b. I suggest you rinse all the media in a bucket of tank water or conditioned tap water. brackish means not much salt but depending on what you want to stock your freshwater tank with some species can't tolerate any salt.

If you just wash it out, it be fine. The salt will re-dissolve in the water when you wash it out.... remember that its best to also wash the media as well, to remove any chances of introducing harmful bacteria and illness.....!

ok I was noticing that the chamber that flows around the impeller and uv light has gunk in it, any idea how to get those places?

also what about the hoses? I plan to wash the filters but i'm trying to get all the old tank residue out (its like brown slimey and caked on in some places)

scrub with a toothbrush and a mixture of warm water and white vinegar, that's on the plastic parts only. The rest of the stuff should clean up with warm water and some elbow grease.
