@Anasmerixindia58 Usually toilet cleaners are very acid, so they can remove scale and have antimicrobial activity. If you increase pH to 7 pH, you’ll only have a mere surface cleaner (only with high sequestering-buffering power), and as
@PhilGeis mentioned, you’ll need a preservative. Now, at very low pH, SLES will hydrolyze (not sure about the acid stability of MES, but I know AOS are commonly use in acid formulations).
