Well, that is probably a trade secret.....but here are a few ideas.....

Explanation:

As far as I know, toilet and bathroom cleaners contain bleach, #Na^(+)""^(-)OCl#, hydrochloric acid, and maybe some some form of scent to make it smell nice.....

When we use cleaners in the bathroom, there is often a residue of calcium carbonate, and the hydrochloric acid acts to give water soluble salts that may be washed off....

#CaCO_3(s) + 2HCl(aq) rarr CaCl_2(aq) + CO_2(g) + H_2O(l)#

And hypochlorite is reduced to chloride ion.....

#ClO^(-) +2H^(+) +2e^(-) rarr1/2Cl_2 +H_2O#

And (I presume) chlorine is a germicide......
