You’ll often find mildew and soap scum in the same place, but they are very different substances. Mildew is a substance composed of living fungi, whereas soap scum is primarily an accumulation of mineral deposits. Mildew needs chronic moisture to thrive, while soap scum is unaffected by damp conditions (though it is a residue left behind by the water).

Before hiring a cleaning service for your home, it's wise to ask several questions. Find out what services they offer, whether they work alone or with a company, and if they can provide references. It's also important to ask if they conduct background checks on employees. Inquire about their scheduling, availability, and when they can provide an estimate. Confirm if they have insurance, offer a guarantee, and bring their own cleaning supplies and equipment. You should also clarify if you need to be home during the cleaning, what arrangements are necessary for pets, and if there is a written contract. Finally, ask how they set their rates and if they are available for emergencies and what those charges would be.

There is value in hiring a professional maid service. First and foremost, having a professional maid service helps save your time; after all, no one wants to spend an entire weekend cleaning their home. Additionally, if you use your maid service regularly, you won’t need to purchase expensive cleaning products as they will bring their own. It’s also important to consider that your maid service can get to time-intensive projects like deep-cleaning the fridge or carpets.

The best method for keeping your grout clean depends on the level of staining or discoloration. For light cleaning, use warm water and a stiff brush (specifically made for cleaning grout). 

Tougher jobs call for a one-to-one solution of white vinegar and water in a spray bottle. Spray the area down, wait 5 to 10 minutes, then scrub with your brush. For even more cleaning power, add water to baking soda until it creates a paste and apply it before the vinegar. If the mess is too much, you can call a local tile and grout cleaner.
