Use a Vacuum.

Yes, it is possible to clean one throughly and not have to replace it. Give it a try, as you have nothing to loose.
I had a similar situation with my 2000 Accord. The brake, battery, and door lights all came on and stayed on. I did a little research online and then called my dealer's service department to verify. There are two possibilities; the alternator or the battery. I could be as simple as needing to clean your battery terminal posts. I popped my hood and found a lovely shade of blue-green coating my connection. I cleaned it off and the lights went out. I probably need a new battery soon, but my lights went off!
No, you do not have to use them. It is not mandatory. However you will find they do help keep the sides of your car clean.
Sell it!
Right ontop of the starer. you can remove and clean but you probably are going to have to remove intake manifold and clean all the carbon. check engine on my 2000 Honda accord v6 came on. codes read not enough air flow, change egr valve. removed and it really wasnt dirty. Honda tech adviced to clean intake manifold. problem fixed.
To check the transmission fluid on the 1995 Honda Accord, just let the vehicle idle for a few moments on level ground. Then remove the dipstick and wipe it clean. Insert the dipstick and remove it again. This will be the fluid level.
You do not need the key in the ignition to make lights work. They are "hot" all the time. The reason you Sid marker lights are coming on at the same time is because you have a bad ground in one of your brake lights. It's allowing electricity to jump from the brake lights to the tail light circuit. Take the brake lights apart, clean up all the rust and make sure they "ground" to bare metal. Problem cured.
Go Down to your local part store and by the best fuel injector cleaner for your car.

just bleed your brakes through each wheel cylinder until the fluid runs clean
