'Really' trimming in powershell

I'm trying to write this data to the Notes field for an AD object, but I'm seeing some extra 'spacing' that I don't want.

First line:first value
 Second line: second value [note the leading space]
 [this continues to the end]
[and then I have an extra blank line that I don't want, but I realize it's because of my `r`n - how can I remedy?]

Am I missing something in my code that would correct this?
 [string]$info = $infoField.Keys | foreach {if ($infofield.item($_) -ne $null) {
                "{0}:{1}`r`n" -f $_.trim(),$infoField.item($_)}}

Open in new window

And then $attributes is applied to the New-ADGroup with the -otherAttributes parameter...

Does this work as expected?
$info = $infoField.Keys | foreach {if ($infofield.item($_) -ne $null) {
                "{0}:{1}" -f $_.trim(),$infoField.item($_)}}
[string]$info = $info.Split() -join "`r`n"

It did line everything up on the leftmost margin, but it also split my key/values where they contained spaces.

So now I have
