Hi Kathy, I just vinegar, water and a toothbrush. It's time consuming but it works great and unlike bleach, vinegar won't yellow the grout.
A paste of baking soda mixed with a tiny bit of water then scrub with an old tooth brush. Not a fun task, but it works :)
Hi Kathy - This is the shower cleaner that we use to help keep grout and tiles clean and minimize the mildew - it works on kitchen grout too. Hope this helps! Hugs, Holly
