Before steam cleaning your carpet, it's highly recommended to vacuum first. This will remove any loose dirt or debris that may be present on the surface of the carpet. When selecting a cleaning solution for your steam cleaner, there are many options available such as store-bought brands or DIY solutions made with natural ingredients like vinegar and baking soda. It's important to note that some solutions may not be suitable for certain types of carpets, so it's always best to check with the manufacturer or seek professional advice before use. By vacuuming beforehand and using the appropriate cleaning solution, you can ensure a more thorough and effective steam cleaning process for your carpet.
