Kindly suggest which one among Acetone, Ethanol and Isopropyl Alcohol is advisable as pre-cleaning agent of substrates (e.g., silicon wafer, target materials etc.).
Dear Samit, thank you for posting this interesting technical question. There are various guides to (pre)-cleaning of substrates available in the literature. For example, please have a look at the following potentially useful link which might help you in your analysis. It suggests the subsequent use of acetone and isopropyl alcohol, followed by deionized water:

(see attached pdf file)
Particularly for the cleaning of silicon wafers please also go through the following link:

Other potentially helpful articles can be found by searching the "Publications" section of RG e.g. for the term "pre-cleaning of silicon wafers":

I hope this helps. Good luck with your work and please stay safe and healthy!
Thank you Dr. Frank T. Edelmann for sharing very useful information and guidance related to my query. I will follow it. Wish for your good health.

Isopropyl alcohol is effective against viruses such as FCV at 40% – 60% concentrations. Ethanol however, is more effective at 70% – 90% concentrations against FCV. Contact time indicates how effective an alcohol is against a target microbe in a given period of time.
Acetone will work fine. The whole point of using isopropyl is that it evaporates quickly, leaving no residue. Acetone is used in every lab for cleaning glassware for the same reason.
It depends on the type of surface you wish to clean and the type of impunity you want to remove. IPA has a -OH functional group and acetone has a -CHO group.
Please provide more details about your requirement.
