You can buy commercial glass cleaners like Windex or Glance at any grocery store that sells cleaning supplies. You can also try removing the soap scum with an all-purpose bathroom surface cleaner, although this isn’t as likely to be effective as a glass cleaner.
You can buy Magic Erasers and dryer sheets at any grocery store. Using a magic cleaning eraser is also the best method to use if you don’t want to put any chemicals or scented products on your shower door.
Be very careful when working with hot vinegar, as it will burn you if you get it on your skin. For best results, leave the mixture on your shower door overnight before rinsing it off. If there’s any scum that doesn’t come off when you scrub it with the microfiber cloth, switch to a stiff-bristled brush and scrub a bit more forcefully.
The paste that forms in the bucket should be about the consistency of pancake batter. You may need to add a bit more baking soda or a bit more vinegar to the mix in order to get it to this consistency. This is the best method to use if there are also hard water stains on your shower door that you want to get rid of.
Be sure to keep your bathroom well ventilated when using toilet bowl cleaner. The odors from the cleaner can be pretty powerful, especially in a small room.
Make sure you apply this paste to the corners of your shower door’s frame, as this is where rust and soap scum are likely to build up and harder to clean otherwise.
You can buy body wash at any store that also sells bar soap. To buy fat-free bar soap, you may need to go to a health and beauty shop or a cosmetics store.
Squeegees tend to be pretty cost-effective and you can usually buy them in the cleaning section of most grocery stores and mass retailers. This may seem like a chore to do in the short term, but it’s much easier to squeegee your shower door after you shower than it is to clean off soap scum that’s been building up for a long time. You should also open your bathroom windows or leave the fan running for at least 30 minutes after every shower. This will help dry out the bathroom and prevent the growth of mold and mildew.
The chemical compositions of baby oil and white vinegar both work to repel soap scum, making it much less likely to accumulate on your shower door. Be sure to rinse the door really well if you use baby oil, since it may cling a bit to the door. You can also use commercial glass-cleaning products, such as Rain-X, to prevent buildup.
