Answer 2

If it's REALLY mildew, a mix of water and 25% bleach will kill it. Since you've tried that, it's probably not mildew.

My suggestion is to pull out the top layer of grout and re-grout the tile. It's pretty inexpensive and easy, and is a good idea to do every few years anyways.

Ask in the tile department at Home Depot or Lowes and they'll show you the right stuff. Should cost about $10 for the grout, $10 for a grout float, and $2 for a good sponge. It took me 2 hours to do 2 showers.

Try Lysol Mildew cleaner- it is like Tilex but better- Mold and mildew are very hard to get control of but once you do, stay on it so it doesn't come back- Be sure to work in a well ventilated area. The main ingredient is chlorine or something that smells like bleach. Also, try Mr. Clean sponges. I hear they do a good job.

Living in Florida, this is an ongoing battle. I even took my pressure cleaner into the shower and gave it a good once over- it worked but what a mess.

Answer 4

Try instant Mildew remover by Rubbermaid.You can get it at Walmart.It works for me when nothing else will.Its not with regular cleaning products,its with the Rubbermaid stuff.

Answer 5

are you sure it's in the grout and not in the caulk? if it's in the caulk, you are fighting a loosing battle... just pull up the caulk and put down new,... if it's in the grout, then buy mean green bleach cleaner it'll work.
