I have tried many of the men's blue designer fragrances, and it's not the type of clean I am looking for. Recommend me fresh, clean, maybe soapy or shower gel ec fragrances.
Hawas Kobra is one of the cleanest and soapiest fragrances I have ever smelled. Like super strong pure soap! Exactly the smell after washing your hands with Dove soap but a million times stronger. If you want to fill the room with a soap smell, this is the one you're looking for. Definitely different than all the usual "blue" type fragrances. (It's supposed to be a dupe of 
Imagination but I can't comment that because I have never smelled any Luis Vuitton fragrances as they're not available for testing anywhere in my country.)
Try 
L'Humaniste and 
L'Humaniste Extrême
These are some of my favorite fresh men's fragrances. L'Humaniste is a lovely freshie, and the Extreme version is deeper / more intense with added soapy notes. I honestly wish all the men out there wearing Sauvage and Bleu de Chanel smelled like L'Humaniste and L'Humaniste Extreme instead. Haha!
My favorite soapy fragrance is one I've newly tried out: 
The Tragedy of Lord George . If you look at the notes you might be like "Rum? What is this, a booze fragrance?" But no, it's like a subtly-scented ultra-high-quality soap accord from what I've tested, with the slightest bit of a woody resin in the drydown.
Infusion d'Iris (2015) Eau de Parfum Marketed towards women but men love it on themselves too, if you want it more masculine, you could try 
Infusion de Cèdre (comes in a new bottle now and is said to be like 
Infusion d'Iris Cèdre This one is more of a 'white T-shirt' kind of clean.
Then there is 
Eau des Merveilles Bleue also marketed towards women, but many women find it too masculine, it is a very different take on 'blue' perfumes.
Vetiver Eau de Toilette a gorgeous and fresh vetiver.
Oh forgot: 
Paper Soap Eau de Parfum This is really Dove soap in a bottle. For me a bit too 'distinct' because it is SOAP from beginning till end, but if you like it that way, it is perfect. Very strong sillage and longevity.

Oh yeah this too for sure! Another super soapy fragrance. I didn't really get any other notes than soap/aldehydes from it either. I probably wouldn't say it's exactly high quality soap because to my nose The Tragedy of Lord George smelled just like normal soap, a traditional white soap bar from grocery stores, so in that sense I personally don't understand the price. But well the bottle is nice and different though. It's also so strong that you can taste the soap even after one tiny spray 😅🧼
