Noob dérailleur help please.

Hey guys! I ride mountain bike trails in Miami. I rode both days this weekend. I have noticed a bit of noise when I crank at cleaning time. Seems one of the derailleur spindles is a bit rough also. I'm not sure if that's fixable. Also the new chain I had installed at my local bike shop is very noisy when I crank. Full of dirt/debris. Is this normal? Can I fix these issues myself? What cleaning products do you recommend?

Thank you for any help you can give!

I've used a spray cleaner and tooth brush to try and get at most of it, but the problem seems to be deeper. Possibly take apart and clean?

What bike and what components? A good bike properly maintained should handle this kind of treatment. A department store bike won't work well even if ridden under completely clean conditions.

OK, it's a good bike, not a Walmart special. Are you riding in sand or sandy conditions? If the problem is in the rear derailleur, first check that nothing is bent or mis-aligned and that the shifting is good. It may be as simple as a cable tension adjustment. If the alignment is good, the pulleys come out relatively easy for disassembly and cleaning.

They fill holes there with sugar sand. So yeah, my entire bottom of the bike is brown and white dust. I know for a fact that the middle spindle is rough. Also the chain sounds horrible. The crank itself is fine. I just don't want to take everything apart. And it was perfectly tuned about a month ago. I have ridden 10 times since then.

It may be time to decide . buy tools take the DIY approach,
or drop it of at a shop, and save your time for other uses..

chains now have Quick links, so they will come apart and go back together.

taking it off and cleaning by soaking in a can of solvent
like paint thinner or kerosene will remove the oil the grit sticks to.
then you put it back on and re lubricate.

Park tools has a special pliers designed to make taking
apart removable quick link chains easier.

Blowing off the now clean after second Rinse, solvent
with an air compressor is a luxury.

Some have quick links, many do not, including mine.

you mentioned a "new chain", IME when a new chain is installed on a used set of cogs and chainrings, it's pretty sure to make more noise than the previous chain. and will likely do so for a while. the jockey wheels may also be in on the conspiracy.

The new chain I purchased does in fact have the removable link. I would like to do this myself, considering I ride these conditions twice a week now. So maintenance could get a little pricey if it's in the shop every other week. Is there any way to fully take apart the center spindle in the x5 derailleur? I would love to remove whatever is causing it to stick. By the way, thank you guys for the advice!
