Your shower is wet, naturally. Water, especially stagnant water, breeds mold, mildew and filth and soap scum buildup also does not help out at all. Mold is not only unhealthy, but is ugly looking too! Everyone needs to clean their showers out on a regular basis. However, scrubbing those tiles can be a difficult task, hard on the arm, elbow, shoulders and back, and can even damage some tile and grout if scrubbed too hard or too often. Luckily, there are many products, options and methods out there to save you from having to put in any scrubbing man power to reveal a sparkling clean shower.
When choosing your optimal cleaning product, it is best to start with the most gentle product on the market and then work your way up to more harsh products if the gentle ones do not work out too well for you. The first step, as always, is to practice safety and glove up. Rubber gloves will most likely be best to make sure that they do not get torn and allow product in. Durability is key here to protect your hands. Also, make sure that the area you are working in is properly ventilated to make sure you are not breathing in harsh chemicals. If at any point, you feel lightheaded, step out and then wait to reenter and continue working.
When using any product for the first time, always do a test on a piece of tile or grout that is small and hidden to make sure it does not cause any damage. Most products that you can buy in a store that offer no scrubbing work in the same or a very similar way. You just spray it on, leave it to settle, and then wipe it off once it has worked its cleaning magic. You can use a sponge, rag, or just water to remove the product which will hopefully reveal nice clean tile.
Vinegar is a great chemical-free option for no scrubbing as well. To use vinegar, fill up a spray bottle (clean one out or buy a new one) with equal parts of a cooking white vinegar and luke-warm water. Now, go ahead and apply the solution by spraying it on the grout. It should be noted that you should not use this vinegar solution on travertine marble or real stone because those materials are too porous to handle vinegar.
Using old rags or even towels on the ground beneath the tiles that you are cleaning will help to absorb any vinegar solution runoff. Allow the homemade vinegar concoction to sit and do its cleaning work for a few minutes and then remove it with a rag or sponge. You may need to repeat this a few times or even make the solution more powerful by mixing one cup of warm water in with two cups of that same vinegar and about a teaspoon of dish soap.
For bad stains on your bathroom shower tiles, you may need to opt for bleach. Before going straight for the liquid bleach, try oxygen bleach, which is usually found in the powder form. You will mix two parts of the powdered bleach with one part water and then apply the paste that it yields to the area on the tile you are trying to clean. Let this sit for about fifteen minutes and then remove the paste with a rag. If this is not effective, you will need to very carefully use liquid chlorine bleach. With water, remove any residue from other cleaners and then use the liquid bleach sparingly. Once applied and wiped off, it will do the trick without scrubbing.
Good luck and as always, especially with liquid bleach, be safe and careful.
