Any flooring will do for the garage. Nothing will prevent you from installing cement tiles, ceramic tiles, carpeting, and linen oleum —another question: how will you clean it if you choose something not quite suitable. Either way, your garage floor will meet all your desired parameters. For me, linoleum works best. I can easily mop up any oil leaks if there are any. Although a few people I know don't sweat it and call in some cleaning company like https://cleansolutionllc.com/commercial-floor-cleaning .

My house has a such messy garage, I yearn to clean it up, but there are so many things to fix and I just don't have time to do it myself before my parents arrive. I really need help. Perhaps you have some options for me ?

For you, I can recommend only one service that I know, which deals with cleaning - https://comfortclean.com/ , but it's really worthy! You can go to the site and see for yourself, if you are interested. I have been using it for three years and they have never let me down. By the way, they work very fast and are never late! So that's what you need!
