Best way to clean a old gross bathroom and toilet?

I have just found the best cleaning idea here on home talk 1 cup of white vinegar 1 cup of hydrogen peroxide mix well..... now for most cleaning jobs even marks on carpet squirt a little dishwashing liquid then add mixture and using toilet brush then flush done this will also clean everywhere in bathroom

Also for stubborn stains in toilet bowl a couple of sterodent denture tablets left in bottom of bowl over night

pour white vinegar and baking soda in the toilet tank and bowl ,let sit until it dissolves the stains, for grout make a mixture of baking soda and hydrogen peroxide and scrub ,for water marks, baking soda and white vinegar into a paste

Try Clorox squirt on blue toilet bowl cleanser. No scrubbing. Just let it set. Flush. Looks like new. The other I just discovered is Mr. Clean sponges. They work great on Microwave ovens too. Little scrubbing.

Use a little bleach. Let it sit for a few minutes and scrub with brush!
