Can you clean the bath tub with vinger

Technically yes, if it hasn't been painted, made out of stone, and is not under warranty. My new fibreglass shower warranty specifically says no vinegar. I use it on my old fibreglass tub, and have used it on enamel too.

I use half vinegar, half bottled lemon juice and 2 big squirts of dish soap in a spray bottle, or dish scrubby. I don't leave it more than 3 minutes or so, then rinse.

I find cheap shampoo cleans the bath tub about as good if not better then a lot of harsh cleaners.

Yes, I use a spray bottle filled with 1 cup white vinegar, 2 tablespoons blue dawn the original kind, the rest water, Will clean and shine it up. I also use that on my toilet bowls and never have hard water buildup

I made my own cleaning solution. I peeled two oranges and placed the peels in a mason jar. Then I poured vinegar to cover the peels. I put it in the refrigerator and waited 2 weeks. After 2 weeks, I removed the orange peels and poured the vinegar solution in to a spray bottle. This makes a great cleaning solution and makes my house smell fresh and clean.
