Inspired by this problem.
If I somehow succeed in removing the rusted bolts and replace them with new ones, how can I prevent the new bolts from rusting and getting stuck too? (Other than removing the tank every x months/years just to clean the bolts.)
E.g. in the bike repair videos they always grease the bolts before reinserting them, I was asking myself if this would work for the toilet tank as well. Since I did not find any mention of this anywhere, I imagine this would be a bad idea (maybe because the grease would allow the water to leak around the bolts?), but I would be interested in your opinions, or maybe if someone has tried it, what were the experiences.
