Never pay to have your silver jewellery professional cleaned again! Karri from South Australia has gone viral on TikTok (@someone__awesome) after demonstrating how she cleans her old silver jewellery.

Karri posted the cool DIY hack from April 13 on TikTok with the caption, "worked in a jewellery shop and charge $10 just to do this," where it was viewed over 1.5 million times.

First, Karri lines a bowl with aluminium foil and adds her jewellery. She then mixes a couple spoonfuls of bicarbonate soda and hot water, and after two minutes Karri showcases the shiny final product.

She told Newsflare: "This is a simple process to clean 925 silver jewellery at home with things you find in your kitchen.

"I used to work in a jewellery shop and we would often clean customers chunky necklaces and rings. Cleaning regularly keeps them looking like new.

"Costume jewellery and delicate jewellery with or without gems shouldn’t use this process."

A simple process to clean 925 silver jewellery at home with things you find in your kitchen. First you line a bowl with aluminium foil, couple spoons of bicarbonate soda, put in your jewellery and then cover with hot kettle water. I added more bicarbonate soda and moved it all around with a fork, because kettle water is hot. Average 2 min in the mixture. Take out of mixture and polish with a soft cloth or a special polishing cloth. Costume jewellery and delicate jewellery with or with out gems shouldn’t use this process as heat can damage gems and isn’t recommended for costume jewellery at all. I used to work in a jewellery shop and we would often clean customers chunky necklaces and rings. If they were really dirty we would use a soft toothbrush to get in between the links. Some people wear necklaces in the shower and sports and there is a lot of build up and then it oxidises with their body chemicals and changes the colour of the metals. Cleaning regularly keeps them looking like new.
