How do you clean a bathtub using citric acid and hot water? I saw it on this site, but cannot find it now. I can't remember if there was more ...... soap, maybe?

    I think it is just baking soda in with the water and acid. Then follow up with a mild soap and water.

    I mix equal mounts of vinegar and cheap bottled lemon juice ($ store), and then add a few squirts of dishwashing liquid, and a bit of water in the neck of a spray bottle. I have been using this for over 6 months and I will never buy bathroom or kitchen spray again. It is also good for repelling ants.

    The ONLY thing that has worked for me, to clean those "plastic" shower stalls and tubs is DAP or is it DEP (?) Citrus Cleaner (from Home Depot). Steps: (1) Using a medium scrub brush, and full strength Citrus Cleaner, thoroughly scrub down scummy areas -- let sit for 15 mins. (2) Add more Citrus Cleaner, on top of the old, and repeat step #1, but rinse off, right after this second application & scrubbing. (3)Very, using a household detergent/laundry detergent/similar soapy liquid, wash off the residue of the oily Citrus Cleaner, so no one falls in your freshly cleaned tub/shower. (4) If you are an A-type, you need to dry it with a bath towel, so that you can admire your new-looking tub/shower. This is a time-consuming job, but worth it. We don't do it often, but when we can't stand the look any longer, it's time to get out the Citrus Cleaner.
