In addition, a higher proportion would lower the pH of the pretreatment agent too strongly into the acidic range, which could lead to damage to the treated surface. A proportion of 0.01% by weight or more, and more preferably 0.1% by weight, is necessary to obtain an effect.

It has been shown that an increase in MOF does not lead to a greater reduction of malodors. However, a proportion of 0.001% by weight is necessary to obtain an effect. Particularly good effects are achieved when MOF in a proportion of 0.01 wt .-% or more and in particular of at least 0.25 wt .-% are included.
