Aside from cleaning tubs with a bleach/water solution (this is my first time cleaning my pvc rack since Im getting some new snakes soon) and I was wondering if anything else other than tubs, hides and water dishes needs to be cleaned?

I have a can of PAM but I am unsure where/if I should use it. Do you guys clean the inside of the actual racks? And if so, what is the best way to do this?
