Given an ideal on a variety with toroidal singularities, we produce a modification , functorial for toroidal morphisms, making the ideal monomial on a toroidal stack . We do this by adapting the methods of [Wło05], discarding steps which become redundant.

We deduce functorial resolution of singularities for varieties with logarithmic structures. This is the first step in our program to apply logarithmic desingularization to a morphism , aiming to prove functorial semistable reduction theorems.
