In a few days it goes soft. I tried splashing the water with washing up liquid but I could not detect a bubble. Is there any other method I can try to detect the leak?

We all have our own ways but mine it to mix up a bubbles solution thats capable of whipping to a froth. Then I use a cloth about 10" square to wet the whole item you're checking bit at a time (bit like you were washing it). For a small leak at HP it is sometimes easy to miss as the tiny air jet will blow away the liquid/bubble preventing a stream of bubbles forming.
Using the cloth method has made it easier for me in the past to detect such tiny leaks which have not been found with the splash or spray method.
