Is it safe to put tin foil in the dishwasher?
You may have seen people raving on TikTok about using tin foil in the dishwasher to get silverware clean and remove tarnishing, however, this could cause damage to the appliance long-term.
Appliance experts at RGB Direct explain: "The hack itself has seen some great successes and has proven to be a great one as the foil will be tarnished through the rinse cycle and come out brown, this means that the tarnish on the silverware will be lifted.
"However, by adding it to your dishwasher it can actually cause more harm than good by scratching the interior particularly if the foil is scrunched up or folded in a way that creates sharp edges. It can also clog the drainage system if the foil rips apart potentially damaging the dishwasher's pump or if the foil comes into contact with the heating element or other electrical components of your dishwasher, it can cause a short circuit or other electrical damage. And with the average cost of repairing a dishwasher being £165 this maybe something you want to avoid!"
