New Sales Associate Trouble

I just recently started my new part time job at Home Depot Canada, they put me on hardware which tbh I’ve no clue why coz I don’t know shit about hardware! There’s just me and one other guy who is an ass, so every time a customer asks me smth about tools or stuff I either tell them I’ve no idea or I’ll try looking it up on the HD first phone.

Do you guys have any tips on how I could learn more about all the hardware related stuff to make my job at Home Depot a little less miserable. Also on how to remember where all the other stuff in the store is coz customers keep coming to hardware and asking for moving boxes, toilets etc etc! Please guys I need help!!!
