The most effective and environmentally friendly DIY method recommended for shower grout is the baking soda and vinegar solution. You can create a paste with baking soda and water, apply it to the grout lines, and then spray a mixture of equal parts white vinegar and water over the paste. The fizzing action helps lift dirt. After scrubbing, rinse thoroughly.
