How can I make over a shower?

cleaning dawn dish soap, baking soda mix into paste scrub with new stiff toilet bowl brush( easier to reach across tub) rinse with hot water then add vinegar scrub again let solution sit on any mineral deposits,soapy scummy areas,pink bacterial build-up, mold,mildew then scrub some more rinse with boiling water or as hot as possible-the boiling water also clears drains--make sure you plug drain while cleaning so your cleaning solution stays in tub/shower/sinks until you are ready to rinse everything then for crystal clear glass straight rubbing /isopropyl alcohol and clean wash cloth( no fabric softener on it and no paper towels both cause streaking and smearing)--just pour alcohol on cloth and wipe glass,mirrors,auto glass;do inside one direction-horizontal and other side -vertically this way you can tell easier which is not clean;if you wipe the shower area at least every couple of days with dawn dish soap hot water & wash cloth the scum/body oils won't build up so much where you need to deep clean it.also after showering when it is loosened up from moisture makes it easier
