Depends on if you want to clean the playfield or if you want to maintain the playfield.
This will clean it - but to maintain the finish and lustre as a post cleaning step then a good quality dedicated Carnuba wax is the way to go. I use the liquid form of Mother's brand. Others like the paste variety.
where do you buy either product? Thanks
Yep Supercheap Auto, Auto 1, Autobahn, Bursons and Repco. Make sure you use a foam applicator pad and remember it's not a polish so just lightly apply it - wait 10 mins and buff off with a terry towel
