cleaning gear

Hey, everyone. I picked up a set of RK3s in white a while back, and well as you can see in the picture they are fairly rough. I just want to clean them up and get them looking as good as I can, because I understand they will never look "brand new" again. I've tried the following to clean them...

Hi all, new divers who just invested in x2 Apeks XL4+ kits for me and my wife. After reading the manual it specifically says about pressurised soaking the regs for around an hour, which I intend to do. TLDR What kit should I get to pressure soak the regs. I was intending to get a "spare air"...

What does everyone use to clean their gear after a dive? Dunk tank, bath tub, old trash can (or recycle bin)? I have been using an old kitchen trashcan that works, its just too small. And i dont need anything like a 100 gallon tank. Thanks for any info you can give.
