I have a small full bathroom that doesn't vent out. About a year ago I updated the vanity, medicine cabinet and lighting. The fixture I chose was a bar with 4 lights but it has no done well with the moisture. The fixture looks rusty. What is the best way to clean this up and stop it from happening in the future. If I need to change the light what is a good high humidity fixture.
I think you ansewered part of your own question. Big mistake to not have a vant and use it everytime the shower is used.
It's even code now to have one.
As far as the fixture goes you get what you pay for.
In most cases it's just not worth the time and money to try and refinish a cheap one.
also, cheap fixtures will not have much paint/plating on them, and in the moisture will go to heck very quickly. as you found out.
sig: if this is a new economy, how come they still want my old-fashioned money?
As others suggested.
No excuse not to.
There has to be a route from the ceiling to the outdoors somewhere. When the vent is added, and routed to the outdoors, consider adding a 15-30 minute timer instead of just an on/off switch. Then your bath can vent out the moisture for long enough to actually do the job, and no one has to remember to shut it off.
Then just about any type of light fixture is going to hold up for many years, without finish degrading.
