Salah will leave Anfield this summer after nine years with Liverpool.
Writing for the Liverpool Echo, Aldridge declared: "It's going to be a hell of a send-off when that day comes in May but my worry is that the season peters out on the other side of the international break.
"Mo won't want that as much as anyone and there is still loads to play for once the action resumes on Saturday. It's time to go out with a bang, not a whimper.
Liverpool have a massive couple of quarter-final ties to come and if the players aren't at it at either Manchester City (FA Cuo) or Paris Saint-Germain (Champions League) then they are in real danger of being mowed down.
"You hope the Salah news has a positive impact, similar to how Jurgen Klopp's news did two years ago, when he announced in January that his time at the club was ending. It can act as the wind in the sails and there is no doubt it powered Liverpool through during that Carabao Cup final win over Chelsea in 2024.
"When the top players look back on their careers, it's never about money. It's about medals and these lads at Anfield have the privilege of playing in front of the best club fans in football, so now is the time to show some fight."
