A savvy woman has revealed her budget hack to keep paddling pool water clean overnight amid the cost of living crisis. Rachael Allenby, 43, shared her sister-in-law's tip, which helps avoid having to refill your paddling pool every day – and its simplicity has left people stunned. Video filmed on June 16 shows Rachael and another family member putting a king-sized fitted bedsheet over the top of the 6ft x 4ft pool. Her sister-in-law, Nicola Sedgwick, 44, had told her this keeps bugs, leaves and other debris out of the water. This means the same water can be re-used the next day - saving both money and the planet. Rachael, who works in precision engineering, said: "I saw Nicola whipping out the fitted sheet and thought it's such a good idea. "I'll 100% be trying it myself! "Instead of emptying it and wasting money and water you can just do this, especially when the pool has only been used for a few minutes. "It keeps all the bugs and debris out so easily - it's such a simple hack." After posting the video on TikTok last week, Rachael, from Bramley, Leeds, saw it amass more than three million views in just a few days. People were stunned by it's simplicity - and vowed to give the budget hack a try. One user commented: "That is genius - last year it took me about an hour to cover mine in clingfilm." Another said: "Smart touch Never thought of that...." A third added: "Why didn't I think of that? Great idea."
