Determine the type of finish on your car: Different cleaning products are formulated for different types of finishes (e.g. wax, sealant, ceramic coating). Make sure you choose a product that is compatible with your car's finish.
Consider the specific needs of your car: If your car has heavy contamination or hard water spots, for example, you will want to choose a cleaning product that is specifically formulated to address these issues.
Read reviews: Look for cleaning products that have good reviews from other users. This can give you an idea of how well the product works and whether it is a good value.
Consider the price: Determine your budget and look for a cleaning product that fits within it. Keep in mind that more expensive products are not always better, and it is important to find a product that works well for your needs
