Reciting Quranic verses, duas etc. thereafter blowing over water and using the water to wash, drink, cook, spray the home with, etc. has proven extremely beneficial.
It was narrated that Abu Umaamah bin Sahl bin Hunaif said: `Aamir bin Rabee`ah passed by Sahl bin Hunaif when he was having a bath and said: ‘I have never seen such beautiful skin.’ Straightaway, he (Sahl) fell to the ground.
He was brought to the Prophet (Sallalahu Alayhi Wasallam) and it was said: ‘Sahl has had a fit.’ He (Sallalahu Alayh Wasallam) said: “Whom do you accuse with regard to him?” They said: `Aamir bin Rabee`ah.’ He (Sallalahu Alayhi Wasallam) said: “Why would anyone of you kill his brother? If he sees something that he likes, then let him pray for blessing for him.”
Then he called for water, and he told `Aamir to perform ablution. He (`Aamir) washed his face and his arms up to the elbows, his knees and inside his lower garment, then He (Sallalahu Alayhi Wasallam) told him to pour the water over him (Sahl).
(One of the narrators) Sufyaan said: Ma`mar narrated from az-Zuhree: ‘And he commanded him to pour the water over him from behind.’
(Sunan Ibn Maajah 3509)
The Prophet (Sallalahu Alayhi Wasallam) said: “The influence of an evil eye is a fact; if anything would precede the destiny it would be the influence of an evil eye, and when you are asked to take a bath (as a cure) from the influence of an evil eye, you should take that bath well.”
(Sahih Muslim 2188)
