Looking for advice on cleaning our shower floor. It's a pebble floor and both the rocks themselves and the grout are turning very white. I've tried cleaning g with various cleaners and none seemed to help. I finally went pretty hard at it with bar keepers friend and it actually made it worse.

Any suggestions on where to go from here?

When you say a pebble finish do you mean real aggregate or a pebble looking finish? If real aggregate I'm not sure if it will work but there's a few methods I found online a few months ago that really worked. Basically, the part that worked best required white vinegar heated in the microwave to heat boiling and then stir in a cup of dawn dish washing detergent. While it's hot pour in the shower and scrub some with a brush. Let it sit a few minutes and then rinse with clear water. It might take a second application but I was amazed how well it worked. I had already tried everything else anyone could suggest.

Real aggregate. I'll give your method a try

You might try Comet with Sanivac and a stiff brush.

Do you know what kind of stone it is? I have travertine in my showers and certain cleaners will chemically etch it, making it look white like you describe. I learned this lesson the hard way and had to purchase some stone refinishing products to (sort of) restore it.

Here's a picture. After doing some more reading, I'm wondering if I just need to apply a wet look sealer because it looks fine when it's wet but turns white when drying out. It also kind of looks like some of the stones have remnants of an old sealer on them.

I've had the same issue. What has helped me the most is using a stiff brush. I put a broom handle on it and really work it back and forth. I've used various cleaners with it but really credit the brush for the results
