Which of the following is/are the cleaning methods after the exposure

1.	Which of the following is/are the cleaning methods after the exposure of specimen?(a) Sandblasting(b) Rubber-stopper(c) Use of chemical and solvents(d) Sandblasting, rubber-stopper and use of chemical and solventsThe question was posed to me in quiz.This interesting question is from Testing topic in portion Corrosion Testing of Corrosion Engineering
Answer» The correct option is (d) SANDBLASTING, rubber-stopper and use of CHEMICAL and SOLVENTS The best explanation: Cleaning methods after the EXPOSURE of specimen: Mechanical methods such as scraping, brushing, sandblasting and the rubber stopper Chemical methods in which chemical solutions and solvents are used for removal Electrolytic methods in which specimen is made cathode under an impressed current.
