Swill with clean water then reapply with boiling water and caustic

the hotter the better it will melt it 2 bits

did one 4 Dordy and it had a real thick old renthal snapped off in it and 4 days was gone

Just keep tipping out the solution and renewing it thats the trick and red hot

Pm me if u want help
