Built in soap dish in shower has old soap crust like stone!
I would need a chisel to get this residue out! I actually made a ceramic liner to go into it (I take pottery classes for fun), that I can remove to wash. But until I can get the old crust out, I can''t use it. I use that Scrubbing bubbles automatic shower cleaner, but it does not seem to have any effect on this, perhaps because the soap dish is recessed into the wall. That must play a role in why this happened in the first place.
It's embarrassing to admit. (Luckily, I have an alias!) However, I had my hands full for a number of years, and details like these were just not a priority.
