I have a shower where the floor is made up of small 1" - 1 1/2" pebbles / rocks pushed into a grout-esq base.
It's a great "outdoor" look for the shower.
...however, each of these rocks over the course of years has become dark. I didn't realize it until I noticed the color gradient of the rocks going from dark near the drain (where you'd stand most of the time) to a more natural lighter color near the edges of the shower.
The rocks have built up waxy / oily grime on them from years of abuse of showering. You can take a flathead screwdriver and run it across the top of a rock and literally scrape off a layer of built up gunk.
I've tried various cleaners on the shower, but everything is too mild. I need something that will really just melt this away.
- Vinegar / Baking Soda
- "Scrub Daddy" / "Pink Stuff" cleaner
- OxiClean (Hydrogen peroxide)
None have made a difference with the exception of the Scrub Daddy / Pink Stuff... and that was a ton of manual work on each individual stone. I need something more buff.
Part of my reason for not wanting to just scrub this away is because the rocks are obviously all different shapes with lots of rounding to them, so this dirt also gets built up around the edges where the rock meets the grout. This is a very difficult area to clean.
