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. 

You can always use a homemade vinegar solution as a natural alternative to commercial cleaning products. To make and use a vinegar cleaning solution, fill a spray bottle with equal parts white distilled vinegar and warm water. Spray the solution liberally across the tub surface. Let it sit for 10 to 15 minutes before wiping it down with a non-abrasive sponge or cleaning cloth, then rinse with clean water. If a line of soap scum is still visible, spray it with the vinegar solution. Use a soft-bristle toothbrush to gently scrub the residue away before wiping it down and rinsing again.

The cost for professional floor cleaning is $250 on average. This cost can range from $100 to $1,500, depending on the type of flooring and its square footage. 

For example, natural stone flooring requires specialized techniques and care, so you'll spend closer to the higher end of the cost range. The cost of cleaning tile and grout is more cost-effective, where you'll pay an average of $0.50 to $3.50 per square foot.

Apartment kitchens and bathrooms take the longest to clean. Bacteria and other dirt build up the fastest in these wet areas. They need more attention to ensure they remain clean and sanitary. If your apartment has two bathrooms, expect to pay a premium for professional cleaning.
