I am not a seller of this item. I googled the issue because it does sound like a issue that impacts the dignity of both caregiver and patient.
I found the following device that may provide a solution. I hope that it helps or provide some additional ideas on solutions.
As for how to clean the area
- a baking soda paste;
1/8 cup of baking soda, slowly add water a table spoon at a time and mix between each tablespoon, until a paste forms. You can add salt to make a more abrasive scrubbing. Then use a cleaning brush or sponge to scrub the mixture into the surface. Apply a thicker coat on grout and allow to dry. Then use a wet sponge to rub it off.
- Borax is another cleaning product alternative you can likely find in any supermarket.
