A "soft-soap artist" is someone who flatters and ingratiates themselves with others in order to gain favour or manipulate situations to their advantage. Synonyms for this term include "smooth talker", "flatterer", "sycophant", "brown-noser", "windbag" and "huckster". These individuals often use charm and persuasive language to manipulate others into giving them what they want, regardless of whether or not it is in the best interest of those being manipulated. People who are adept at using flattery and persuasion to achieve their goals can be difficult to deal with, and it is important to watch out for their manipulative tactics in order to avoid being taken advantage of.
