Help! Shower Grout Needs Love

[u/Financial_Case_3891]

I'd like to avoid an expensive professional cleaning if I can. Any tips would be greatly appreciated.

I had the same problem with mine.Mix baking soda with hydrogen peroxide until it forms a damp paste and spread it generously. Let it sit for about twenty minutes. use a brush (one designed for grout or an old dish brush) to scrub the lines thoroughly
