Simply make up a spray bottle up with household bleach and water. 1:4 parts bleach to water. Obviously keep the spray bottle handy in a cupboard or cabinet in your bathroom. Once you shower spray the tiles with the bleach solution....Leave for a good while then rinse quickly. This will keep mildew from building up on your tiles and leaves them with a sparkle.
Cleaning soap scum residues can be a hard, laborious task....BUT by using lemon oil furniture polish you can prevent the build up by creating a barrier. So the next time you clean your shower and shower door, you can wipe it with furniture oil with a soft duster. Let the oil be for a couple of minutes, and polish off any excesses with a dry cloth.
The furniture polish has now coated the area and will act as a buffer against any soap scum residues....Helping you in the long run as now it will be easier to clean.
What to do in this case to remove stubborn mineral deposits on glass shower doors or indeed screens is simply to use clear vinegar, bicarbonate of soda and salt....No armful chemicals here!
First spray the vinegar onto the shower door or screen and let it sit for around 10 minutes; then make up a paste using equal amounts of bicarbonate of soda and salt. Using a damp sponge rub the paste over the door, then rinse off well using warm water.
Mildew on grouting is always a chore...But listen the good news is that mildew is really no problem at all when you use vinegar. Simply pour some clear vinegar into a container, then dip an old toothbrush or other small similar cleaning brush into the vinegar then scrub the mildew. Alternatively pour the vinegar into a spray bottle, spray over the affected areas, and let it remain there for about 10-15 minutes. Rinse with hot water and scrub with the toothbrush or small brush if required.
