I have had good luck with the spray tile/bathroom cleaners sold at the grocery stores. They do need to be used frequently/daily to be effective.

Stop using bar soap and use the liquid bath gel. It is the powder in bar soap that leaves the scum.

After cleaning shower doors and walls, use GLOSS-Gel (get at Home Depot) on the walls and doors.

Once a week after shower use a nylon bath scrubbie on the walls while rinsing. The little bit of residue will rinse off easy, no hard scrubbing. Shower will last months before a heavy duty cleaning is needed.

Put in a hand held shower head, then use it to rinse the walls and doors each time shower is used.

Squeege shower every time.

Open shower door and let a fan blow in it for an hour.

Shower keeping is a breeze by doing the above, not that much trouble either.

It is moisture in bathroom that causes mildew and the fan will help dry it out faster preventing mildew.

A person who worked for a cleaning company suggested car wax/boat wax and waxed the tile. Has anyone else used car/boat wax?

i did I learned that when i worked for Amway,after you clean tub good,dry use car wax,lasts a long time,I also wax my stove,I have an aga,black,looks great helps protect it from splills easier to clean up messses and shine!

Finazzle soap scum remover is the best. They sell it at Ace Hardware.

I swear by Shower Power. Spray it on, soap scum rinses off. Used to get it at Kmart..have not bought any in a while because I stocked up when KMart was closing down. It comes in a blue opaque spray bottle.
