rubber mats?

[1jjpop]

I have A 18x24 garage on a lot that I own,it has had tractors stored in it for years,[they leaked oil & grease into the floor] I tried different things to clean the floor,think maybe a mat over the floor would be the eazy way out. I use it for a shop[ oil changes and etc.] & a storage area for my toys. What rubber mat the best, best price, what thickness best?? do you have pictures???
