You mean scrub with that sponge made out of plastic? Because you definitely want those crevasses clean. And how hot should the water be? You have 70 degree Celsius water coming out from your tap?
But hey, I used to do that. No matter how much you take care of them, the hot water wash and drying leads to those chopping boards splitting after so many uses. Those plastic buggers last for years.
I have a bamboo cutting board that I purchased in 2004, and a mesquite wood cutting board gifted to me a few years later. Both look nearly new despite using them daily.
Now I don't cook meat, so maybe that is why my experience doesn't match yours.
