Defunkify a Boy Bathroom! 1.) Make a paste with baking soda and freshly squeezed lemon juice (a natural disinfectant.) I used one lemon, it was plenty. 2.) Apply the paste liberally to all the places around the toilet that get a lot of over-spray, especially the base of the toilet. 3.) Let it sit for 15 minutes. 4.) Then spray it with white vinegar and wipe it down with a damp rag.
