The upstairs toilet in our house has a gender-specific problem: the seat won't stay up without being held up. This is because the lid of the cistern sticks out a bit too much, so that the seat's centre of gravity is slightly on the wrong side of the hinge. I already replaced the seat when we moved in, it didn't make any difference: basically, the holes in the toilet where you attach the seat are a bit too far back.
I'm not going to try to fix this (very annoying, only for me) problem by replacing the toilet, or just the cistern. But, what would work, if it's possible, is to make the seat a bit more stiff, ie resistant to movement. It's only just on the wrong side of the vertical, so that if the hinge was a bit stiffer, i believe it would stay up by itself, without being resistant to movement in general (obviously it still needs to be lowerable so gluing it in a fixed position isn't an option).
There's no way to adjust the hinge, ie no screws to tighten, and it can't be taken apart without breaking it. So what i'm after is some sort of "anti lubricant" that i can put into the hinge. The hinge (on each side) consists of metal (or perhaps chrome-plated plastic) cylinders, which butt up against each other, similar to in this photo:
If i do put an "anti-lubricant" in there, it's going to have to be something that will be able to get into the tiny space between the rotating parts of the hinge.
Does anyone know of such a substance? Or have any other solutions? thanks, Max
EDIT: I have a 1 year old running around, so any solutions need to be child-friendly: that means that if the solution uses magnets, for example, the magnets need to be very hard to swallow.
EDIT2: i wanted to put a photo up of my solution, which was suggested by @handyman in the correct answer below:
Before on the right, and after on the left. Basically i unscrewed the seat and lid, loosened the discs that hold the hinges and rotated each one 180 degrees. Fortunately i was able to rotate the vertical posts that hold the actual hinges as well, to keep the hinges pointing in the same direction as they were originally, but just an inch or so further forward, which made the crucial difference.
