OMGoh I believe this! people are nasty with their jewellery.
story one: I was visiting a client and an old lady came in and ask my client to clean her earrings, due to arthritis she couldnt remove her earrings. she asked me to do it. I have no idea why me, she had no idea who I was. I could have been another customer! I let my client handle his customer. he took one look at the earrings and went and grabbed some latex gloves...they were that bad. dirty, crusty her dead skin cells had basically crawled over the top of the stud and were engulfing the earring like wtf!!!
story two: I was visiting another client and when they have repairs for our wathes and i'm in the area I pick them up and bring them back to the office- it saves them shipping charges.
they gave me a repair and all they said was it's not working. I took the watch out of the repair drop bag and instantly wished I didn't touch it! the sapphire crystal was caked with what looked like old food and the band was actually corroding away...the watch was less then a year old. the watch was so dirty that whatever was on it was actually eating away at the rose gold plating and corroding stainless steel. and then the customer was actually mad that his gold plating was coming off and wanted it fixed for free!
people- clean your earrings. take them off soak them- take a tooth brush and clean them and sanitize them! I swear by removing jewellery and cleaning your pieces the world will not end and your pieces will look infinitely better and sparklier
