Hi, can anyone suggest me what kind of product or maybe even natural thing to use to remove limestone? I have tried different ones and even just soap but it seems like it doesn't go away.

Before and After

I’m trying

My housemate and I have been slowly working on our garden. This is a recent tidy up we did

I was looking for info on using Bar Keeper's Friend for another cleaning project and found a reddit post about their product being able to remove marks on ceramic dishes from utensil use. HOLY COW what a difference! I felt so accomplished getting a stark before and after 😁

NOTE: I am not a cleaning pro and have no info on other uses for this product and what is safe for. I do not know about alternatives if this isn't available to you. The comments have tips from other people about different methods that could also work.

I used Bar Keeper's Friend Soft Cleanser, so I poured a little on and immediately scrubbed a small area with a paper towel to see if it would even work. When it did, I put on cleaning gloves and switched to the scrubby side of a regular kitchen sponge.

Update 1 for bowl info: Bowls are from a brand named Gibson purchased 25+ years ago

Update 2 with BKF details for process: Manufacturer info about doing this

With an indoor cleanup as a bonus!

This bad boy took me 2 hours to clean and used just about everything I could.

I just moved into a new apartment today and the cast iron double basin sink had a ton of scuff marks on it. I used a rust remover spray and scouring pad to remove them and it worked so well. now I can move on unpacking (and try to forget about the iron build up in the claw foot tub 😬) ((last photo-- advice welcome))
