How to clean bathtub?

I use scouring powder, like Comet or Ajax and a brush or sponge. Once it has been cleaned, you can use Scrubbing Bubbles spray once a week and just wipe it down to get the same results. Good luck!

What is on the bathtub?

Easy Off No Fume Oven Cleaner in the BLUE can. Spray it on, let it foam and sit for a while. Rinse away.

First try white vinegar and baking soda mixed into a paste ,apply and leave on over night,next see if any of what you call gunk came off,Use a mr clean magic eraser, at that point see what is still there and shout out to us.

I use vinegar, baking soda and dawn dish detergent. I put it in a bowl in the shower. First the vinegar then add the baking soda and add the Dawn and after it fizzes out I use a rag to rub up on the sides and wall. I make more if needed. Its safe, and no fumes and cheap. I don't have to clean it as often since I have been doing this. Love it.

I use equal parts blue Dawn and white vinegar in a spray bottle with a magic eraser.
