A toilet in a guest bathroom that doesn’t get used very often can usually be cleaned less frequently, but toilets that are used regularly should be cleaned every week. Cleaning your toilet more frequently than once per week is usually unnecessary.

Only if the dishwasher isn’t made of stainless steel. The corrosive chemicals in bleach will stain stainless steel and can also cause further damage. To stay on the safe side, stick with an extra cycle of vinegar to banish any lingering odors.

As a general rule, you should clean your oven at least every three months, though this depends on how often you use it and the amount of residue buildup. A clear sign that your oven needs cleaning is if you notice smoke or a burning smell during use. Many ovens have a self-cleaning cycle, which heats the oven to an extreme temperature. If you use this feature, stay home while it runs and consider ventilating the room, as it can create smoke. For manual cleaning, you can make a paste of baking soda and water or use white vinegar before resorting to harsher, store-bought oven cleaners.

One of the best ways to prepare for a home biohazard cleanup is not to touch anything. Do not remove belongings, even if they are of value or importance, from the area as they are likely contaminated. It’s essential not to use any cleaning products of your own, as the cleaning company will be using chemicals that could interact with your products. 

One thing you can do to prepare is take pictures of your space and belongings that need to be cleaned, especially if you plan on filing a claim with your insurance company. In addition, take time to make a list of items that are valuable, sentimental, or otherwise important. The cleanup company must evaluate these belongings to make sure they are safe.
