Spanish say " Yo friego los platos", people may understand you in Latin America but as Hairo said, here verb Fregar colloquially means to bother someone. greetings!!

It's a not frego, Its friego. Aparte de eso, ambas están bien :P, Aunque de hecho no sé donde usen "fregar". Usually in most countries "fregar" means "to bother/annoy etc" in colloquial speech. Yo lavo los platos ( chile.. ecuador.. argentina etc ) Yo lavo los trastes ( mexico ) Yo lavo la losa ( colombia )

Puedes utilizar los dos: fregar los platos o lavar los platos
