How do I get rust out of a porcelain bathtub?

Hello, I use the works toilet bowl cleaner. You don't even have to scrub or anything. Make sure you get the regular one and not the one that basic. I made that mistake once. Just squirt it on and let it sit a couple of minutes and then rinse away.

I meant to say the one that says basic on it.

Do not use toilet bowl cleaner in the tub. The tub coating is different than a toilet bowl finish. It will etch the porcelain in the tub over time.

Squirt Dawn dish soap over the stain. It HAS to be Dawn. The generic brands wont work as well. Just straight from the bottle. Squirt! Then let it sit for a few hours. Then go back and doused the tub with vinegar and scrubbed with a sponge. Ithen spray it again with vinegar and let that soak. Lastly, scrub with the magic eraser. Depending on how bad your rust spots are, you may have to repeat a few times!

Hello there. Cindy here. Make a paste with baking soda and water. Spread this paste on the rust stain. Let it set overnight. The next morning, gently scrub the paste away using a microfiber cloth. Rinse any paste left over from the tub. If the stain is really bad, you may have to repeat. I hope this helps you. Best wishes and good luck.
