That's why I decided to make my own shower spray. It's very easy to make. Using a daily shower spray will help reduce the accumulation of mold and mildew in the shower, requiring major clean ups less often.
There are a variety of recipes online, most quite similar. There are vinegar based recipes, alcohol base recipes and some using various combinations of ingredients including soap, hydrogen peroxide or tea tree oil. I've been using an alcohol/water recipe and it has worked out pretty well. Take a look at the link below or do some additional internet searching to find a recipe you like. Then gather your ingredients, measuring utensils, and an empty spray bottle. Get mixing and give it a try!
