    How would you remove seriously rusted toilet cistern bolts? (under cistern) they are beyond help from a spray, the rust has grown. I thought small angle grinder or multi tool.

    you will need to capture the top or bottom of the naughty bolts otherwise they will spin and just be troublesome.its often easier to capture the lower ones with grips as they have wingey nuts

    Be very careful, I use a grinder, by the time you have got 1/4 to 1/2 way through , the heat generated usually lets you screw the wing nut off .

    Each to their own sometimes based on the amount of room you have.

    Just done one! Could only just get a hacksaw blade in, no way on gods earth a grinder or multi tool. At least with hacksaw you are unlikely to damage cistern/pan- be careful with grinder!

    Sounds like you went between cistern & pan rather than attacking the nuts underneath.

    Club hammer...destroy the fecking thing.

    Mini-recipricating saw with longish blade, perfect for that sort of thing.

    Hacksaw blade wrapped in a rag, a pair of gloves and something comfortable to kneel on.
    And patience.

    Pair of decent pliers or grips and as Simon says snap them off.
