Cleaning a Stained Bathtub

I'm in the process of moving into an old historic home and boy, does it need work! The porcelain bathtub was disgusting, years worth of stains. For three days, I tried every "soap scum, mildew remover, etc." you could think of. Nothing worked (cue freak out) until I came across two lifesaving products.

1. Pumie Pumice Scouring Stick from Lowe's. $2.83 each. I used 4=$11.32. This is safe on porcelain, not enamel. Just wet the stick and scrub. It immediately started really removing stains. Once I ran out, I didn't feel like getting back in car so thought I would give the next product a try.
   

2. Bar Keepers Friend Cleanser, $2.50, local grocery store, Wal-Mart, Lowe's, etc. This stuff is amazing! I let it sit for a few minutes and scrubbed and it took everything nasty right off. I will never use another cleaning product! It's cheap and can also be used on so much more than just the bathroom.

So, including some scrub brushes from Dollar Tree, I spent around $16 and it looks like I bought a new tub! (The pink bottle in corner is just a cleaner I already had to wipe down tile.) I was so thrilled with outcome, I wanted to share with everyone! Hope this helps!

P.S. I forgot to take a legit "before pic". This before pic is right after I had started using the pumice stick. You can tell where it's been used on the right of pic.
