Alongside his partner Johannes Radebe, Whaite performed a paso doble inspired by Pirates Of The Caribbean.
They were scored 39 by the judges, with only Craig Revel Horwood not giving the pair a perfect score.
Judge Anton Du Beke said: “I’m a little overwhelmed, really.
“I have to be honest with you, I thought it might be a bit camp, this number.
“It was the best thing I have seen all night. You were so strong and believable and powerful.”
Shirley Ballas added: “I haven’t seen anything like that. Thank you for closing our show with such a magnificent performance.”
The routine received the highest score of any dance from the series so far with the Chorley-born star who grew up in Wrightington, Wigan, continuing to impress.
CBBC host Rhys Stephenson and his partner Nancy Xu came second with a score of 37 for their Spider Man-inspired routine.
Third in the rankings was EastEnders actress Rose Ayling-Ellis.
She was scored 36 by the judges, who each gave her a score of nine for her foxtrot to the Titanic theme song My Heart Will Go On.
Whaite's fellow Lancastrian AJ Odudu, from Blackburn, and her partner Kai Widdrington, scored 35 for their American smooth.
