Which of the following is not an excess penetrant remover?(a) Solvent

1.	Which of the following is not an excess penetrant remover?(a) Solvent removable(b) Water washable(c) Lipophilic pre-emulsifiable(d) Lipophilic post-emulsifiableI have been asked this question in my homework.My question comes from Dye Penetrant Test in section Non Destructive Techniques of Casting-Forming-Welding II
Answer» The CORRECT choice is (c) LIPOPHILIC pre-emulsifiable The best explanation: A penetrant remover MATERIAL HIGHLY depends on the type of material by which the penetrant is made. Among the following, a lipophilic pre-emulsifiable is not a type of excess penetrant remover.
