Hot Shot utilizes new, high efficiency, biodegradable detergents and solvents for remarkable results. Hot Shot is a very strong degreasing/cleaning solution that completely dissolves grease and dirt. Hot Shot's versatility allows it to be used not only for degreasing of engines and related parts, but also may be used to clean wheels, tires and the under body carriage. Hot Shot may be used full strength on tough applications, or may be diluted with water for lighter cleaning.
