DIY MOLD REMOVER... Choose one of these two mixtures: 1/2 cup hydrogen peroxide and 1 cup water or 1 tsp tea tree oil and 1 cup water. Mix the two ingredients chosen in a spray bottle. Spray the mold/mildew and allow to sit for an hour. Rinse and wipe clean (you may need to scrub tougher mold).
i got a free can of scrubbing bubbles- works like oven cleaner but without the harsh chemical smell. Beauty for this type of tiles. The vinegar is better than bleach, i think, for mixing with the baking soda- for my lungs anyway. Bleach in my shower would nearly take me out! Ahaha- i'm a pillar of strength, eh? B)
