Put your silver on after applying your perfume. Making sure that the perfume has completely dried before you start putting your jewellery on. If possible, avoid spraying the perfume onto the places you know your jewellery will sit. The alcohol in the perfume can damage the silver and cause it to discolour. The same rules apply with any type of moisturisers, body butters, tanning lotions, hairsprays, spray on deodorants or in fact any other aerosol product, many of them contain alcohol or other solvents that can be harmful to your silver.
Avoid wearing your jewellery to bed, chains and bracelets are especially susceptible to breaking and being damaged in other ways when asleep. Also it is a great idea to take your silver off before you get in the shower, the bath, hot pools, spas and when swimming. The chlorine and other chemicals in the water, soaps, shampoos and body washes can not only make your silver turn grey or even black but it can also corrode the metal leaving it looking unsightly.
It is also a good idea to remove your silver if you are doing manual labour of any kind. Everything from simply weeding the garden through to building a house can damage your silver items. Taking your silver off when preparing food not only protects the silver but is also good hygiene practice, even if you are wearing gloves. There are many other situations where you should remove your silver. The more you look after it the longer it will last and the better it will look.
Silver is a precious metal and should be treated as such.
