- providing tableware;
- and
- contacting the tableware with a composition comprising a zwitterionic sulfonated silane;
- wherein the zwitterionic sulfonated silane has the following formula (Formula II):
- (R1O)p—Si(Q2)q-W—N+(R2)(R3)—(CH2)m—SO3− (II)
- wherein:
- each R1 is independently a hydrogen, methyl group, or ethyl group;
- each Q2 is independently selected from hydroxyl, alkyl groups containing from 1 to 4 carbon atoms and alkoxy groups containing from 1 to 4 carbon atoms;
- each R2 and R3 is independently a saturated or unsaturated, straight chain, branched, or cyclic organic group, which may be joined together, optionally with atoms of the group W, to form a ring;
- W is an organic linking group;
- p is an integer of 1 to 3;
- m is an integer from 1 to 4;
- q is 0 or 1;
- and
- p+q=3.
