T-SQL setup String

I pass a string to my stored procedure that can be setup in different formats. I trying to use Trim, replace, CharIndex and such to format it in a way I can use. Here is what the string usually looks like when passing:
'Widget1, Widget2, Widget3                          
Widget4, Widget5, Widget6                
Widget7, Widget'

It might be hard to tell from this but say after Widget3 there are a bunch of spaces. This is what I need the string to look like:
'Widget1, Widget2, Widget3, Widget4, Widget5, Widget6,  Widget7, Widget8'

so a coma after each widget or remove all comma and have one single space. either would work

That removes the spaces but how do I add the missing comas?

I have this so far
SET @Parameters = LTRIM(RTRIM(@Parameters))+ ','
set @Parameters = replace(@Parameters, ' ', '')
set @Parameters = replace(@Parameters, CHAR(10), ',')

Problem is it puts the coma on the next row as oppose to next to the "Widget". like this
'Widget1, Widget2, Widget3
,Widget4,
