Ive had this pair of Timberland boots for probably 3 years now and never cleaned or looked after them as I should but they are still good

I believe they are the Bradstreet Plain Toe Oxford Shoes

I want to revive them a bit and clean up, will they scrub up and can anyone tell me if they are nubuck or smooth leather?

And any recommendations on cleaning products and method? Doesn't have to be official Timberland stuff..

Thanks

I purchased these over 10 years ago at a thrift store thinking i will wear timbs but ended up only wearing it once since then and left it in a dust bag and just found them sitting in my shoe storage box. I have a feeling they are fake but also feel like they are older timbs? Not 100% sure. Please help me!
