If you are about to clean a car's carpet and do not already have carpet cleaning chemicals on hand, then you might be interested in knowing how to pick the best ones for your car. You will want to choose a carpet cleaner and/or disinfectant, avoid bleach unless your car carpet is white, and ask a professional for help if needed.
Cleaning Vs. Disinfecting
Unless your car's carpet is already clean, then you will want to find a carpet cleaning chemical as opposed to a carpet disinfecting chemical. This is because disinfecting chemicals generally only work on surfaces that are already clean - they can't kill germs on surfaces that aren't free of miscellaneous materials such as dirt, crumbs, or other materials. Sometimes, you can find disinfectants that also clean carpets, but in general you will need to find and use separate products to both clean and disinfect your auto carpet.
Avoid Bleach Unless It's White
If you are interested in using (diluted) bleach on your carpet, then you will want to make sure that the carpet of your car is light enough that any bleach used won't stain. If you use bleach on carpets that are too dark, then your carpet will stain anywhere that you use it. Additionally, it's nearly impossible to just try to stain the entire surface with bleach to try to cover it up, as it's difficult to spread the breach solution evenly. If you aren't sure if the bleach will work for your carpet or want to double-check that other cleaning chemicals you use will work, you should test a small part of your car's carpet.
Ask A Professional
Finally, if you are struggling to find a carpet cleaner that works for you, then you may want to ask a professional auto service or other car cleaning professionals as to what chemicals they prefer. Many of the products that automobile cleaners use for cars they service on a regular basis are also available to regular consumers, although probably in smaller amounts since you'll only be cleaning one car. There's nothing wrong with asking your local auto service shop or freelance car cleaner what they recommend that you use on your own car. If you still haven't found the right chemicals, then you can always get a professional cleaning instead.
