There are only three products that advertise car wash liquids, namely lavender concentrated foam car wash wax (BD1019) for general stains, and self-adhesive remover (B-7391) and asphalt cleaner (B-1791) for stubborn stains.
 
BD1019 is a washable product, and the foam is very fine and rich when mixed with water, which can quickly wrap the stain until it is washed away from the body. In addition, BD1019 also has a reverse osmosis water purification formula, which can enhance the cleaning effect and is not easy to produce water marks after washing.
 
B-7391 and B-1791, the two cleaners advertised as for stubborn soils, are both sprayed and very easy to use, and B-7391 self-adhesive cleaner can be used for both vehicles and homes, and has a very good cleaning effect on body sticker residues. B-1791 is known as the "tar buster" and has a good cleaning effect on stubborn stains such as asphalt, asphalt, and insect stains. It is recommended that consumers choose according to their actual situation. The advertised car wash liquid products are mainly 0.5kg small specifications, and the price is less than 20 yuan, which is relatively moderate.
