Removal of boot rubber!

[Pheasant Plucker]

Anyone got any ideas about how to remove burnt on boot rubber from an exhaust?

Tried white spirit, meths and petrol (on the bike!) but to no avail.

Tried warming it up again but it's burnt on good.

I know I shouldn't have such big feet!

oven cleaner on warm pipe. Mr Muscle! Spray it on, leave it an hour or two, wipe off....

On my stainless pipes i have wrapped some soft rag around a block of wood, i then use a very fine cleaner like solvol autosol.
It works perfectly on my stainless ones but you will need to take care on chrome
