In addition to deep cleaning your Incall, ladies what precautions are you taking?

I’m laughing at my little set up I have going on here (specifically my very detailed sign of instructions on the soap) it’s funny but super essential at the same time.  

Ladies, any tips to share?  
Gents, any suggestions to make so we’re all comfortable and safe?  

Who travels with a label maker!?!? lol
...I guess they don’t call me anal for nothing!
