How can I remove a toy car from my toilet pipes?

I have a 2 year-old locksmith who is completely fascinated by the workings of our toilet. This is the fourth time he has done this and we can't keep the kid behind a locked, childproofed door.Maintenance refused to help this time. I've snaked 3 pair of panties, half our toiletries, and 2 toy cars (approx. 3"x 2") My assumption is this is what is behind the problem. They are plastic, so I'm hoping a solvent may be used without harming the plumbing please help!|||I feel for you, mobby dick ended up in ours. Finally my husband gave up after days of everything you did and more. He ended up taking the toilet out and he still gets angry when he thinks of it. We found mobby stuck in there after taking it out into the yard and pulling it out with a home made tool he made to pull it out.My husband is a fabricator. Anyway, something just will not come out and there doesn't seem to be anything that will break it down. So you may want to think about pulling it out , but make sure you have a wax seal to replace the one you will break taking it out. Good luck.|||Solvents should not be put in the commode or any septic system, nor should any drain cleaner be put in a commode. The drain cleaner can actually crack the commode due to the heat produced. The toy is probably stuck in the bend (trap) of the commode. Even if you remove the commode to look for the toy sometimes they can't be seen to be removed. Sounds like some discipline is in order as these mishaps can get expensive.|||Robert, If the toy actually got flushed down the toilet and it's not stuck in the toilet itself, there is nothing you are going to be able to do unless, it ends up causing a blockage in the sewer line in which case, the line will have to be snaked. Good luck
