Assuming you are not shooting ammo with corrosive primers, a rifle should be cleaned prior to prolonged storage, or when accuracy or reliability drops off. Most modern rifles are cleaned too much, which can wear the rifling. A .22 rimfire probably needs cleaning after 1000 rounds. A centerfire rifle, 500 rounds.
"Take the suit in the car and have it cleaned." - is understandable. But, "take the suit from (or out of) the car and have it cleaned" is better.
To correct the unclear reference, you must reword the sentence. The sentence isn't clear that the pronoun 'it' refers to the suit or the car. Reworded: Take the suit to be cleaned when you take out the car. Put the suit in the car and take the car to be cleaned.
Yes, you can take an empty oil can on an airplane. The oil can must be cleaned and can not have any residue in the can. The residue can be cleaned by using hot soapy water.
Pet rats don't have to be cleaned. They are fanatic groomers, and take care of it themselves. -Rat girl <3
Not until you take your head out.
Start by unloading the rifle, and operate the action several times to be sure it is empty. Point rifle in a safe direction, release safety, pull trigger to drop the striker. Unfasten the takedown screw on the underside of the stock, and remove action from the stock. Unscrew the receiver plug at the rear of the action (careful- under some spring pressure). Pull bolt handle back, sliding action spring and bolt out. Draw bolt handle straight out to the side, and draw bolt out of the action. STOP. Do NOT attempt to disassemble the trigger group. No, really- DON'T. It can be cleaned with spray gun cleaner. Barrel can be cleaned, and bolt and inside receiver can be cleaned. Contact Remington for an owner's manual for your rifle.

The faulty reference in the sentence can be corrected by clarifying what "it" refers to. A suitable rewrite would be: "Take the suit from the car and have the suit cleaned." This eliminates ambiguity and makes it clear that "the suit" is the item to be cleaned.

If there is no maker's name on the rifle, it is likely a (former) military rifle. Without a full description of the rifle, and ALL markings on the rifle, there is no way that we can answer your question. Your best bet would be to take to rifle to a local gun dealer. Sorry-
