Using InStr or Left/Right to check variables within reverse loop - excel

Question

At work I have a repetitive task of going through a list of account activity and changes where I have to delete blank spaces and lines that are not necessary for the maintenance I perform. For 80% of the these I am able to work a for each loop that is pretty inelegant but effective.
Example:
For Each c In ActiveSheet.UsedRange
If InStr(1, c.Value, SubString7) = 1 Then ' find earn lines and remove
c.EntireRow.Offset(1).Delete
c.EntireRow.Clear
c.EntireRow.Offset(-1).Delete
End If
Next
The substring is the descriptive title line for each type of transaction. The one I am having trouble with is variable, while the others are not. It can be 9 lines long or 6 lines long, and could also be positive or negative but each possibility comes with the same title line.
Based on everything I could find to try to figure it out, I need to use a loop, moving from bottom to top. I cannot get it to trigger with either InStr, nor left/right.
This is a cut down version of what I am trying now:
lr = Range("A" & Rows.Count).End(xlUp).Row
For rowcounter = lr To 0 Step -1
If VBA.Strings.Left(Cells(rowcounter).Value, 11) Like "Earn Manual" Then
If VBA.Strings.Left(Cells(rowcounter + 5).Value, 1) = "-" Then
If VBA.Strings.Left(Cells(rowcounter + 6).Value, 3) = "AVG" Then
Cells(rowcounter).EntireRow.Offset(5).Delete 'this, several more times with different offsets for the required lines
Else
Cells(rowcounter).EntireRow.Offset(5).Delete 'different ones, finalizing removals on the negative value items
End if
Else
If VBA.Strings.Left(Cells(rowcounter + 6).Value, 3) = "AVG" Then
Cells(rowcounter).EntireRow.Offset(5).Delete 'again, but with different offsets
Else 'There is one line for these that I have to split into two lines, not sure if this will even work as I cannot get it to trigger
Cells(rowcounter).EntireRow.Offset(8).Delete
Cells(rowcounter).EntireRow.Offset(7).Delete
Cells(rowcounter + 4).Value = VBA.Strings.Right(Cells(rowcounter + 3).Value, 25)
Cells(rowcounter + 3).Value = VBA.Strings.Left(Cells(rowcounter + 3).Value, 13)
End if
End If
End If
Next Rowcounter
I had originally had that first If line as:
If InStr(1, Cells(rowcounter).Value, SubString8) = 1 Then
I tried switching to Left() and Like but still no dice.

If ws.c("A" & i + 6) Like "Avg*" Then
Set Deleteme = c.Range("A" & i, "A" & i + 8) ' shows AVG, negative value
Else
Set Deleteme = c.Range("A" & i, "A" & i + 5) ' no AVG, negative value

Set Deleteme = c.Range("A" & i + 5)
Else
Set Deleteme = c.Range("A" & i, "A" & i + 3)
Set Deleteme = c.Range("A" & i + 5)
End If
End If
Else
Set Deleteme = Union(Deleteme, ws.Range("A" & i))
End If
Next A

There is no way that I can get this 100% correct because it was based of the OP's new and improve code, which has some flaws in its logic. My goal was to simply the overall syntax to make it easier to get right.
The problem with deletion with offset values is that the values move on you. My solution is to Union all rows to be deleted and delete them then after the loop is done. This is not only more efficient but it allows us to loop from top to bottom. This makes the code it much easier to follow.
When Union ranges in this way, you must first test to see if the target range to be deleted is Nothing. If the target range is Nothing, we Set it to the new range else we Union the two ranges. I wrote a subroutine UnionRange(), so that we would not have to repeat this process each time we needed to do a Union.
With blocks, Range.Offset() and Range.Resize() were used to simply the syntax. I feel like this is cleaner than concatenating addresses inside of a range (e.g. Range("A" & i + 5) and Range("A" & i, "A" & i + 8)).
Sub CleanUp()
With ThisWorkbook.Worksheets("Sheet1")
Dim r As Long
Dim rUnion As Range
For r = 1 To .Cells(.Rows.Count, 1).End(xlUp).Row
With .Cells(r, 1)
If .Value = "" Then
UnionRange rUnion, .Offset(0)
ElseIf .Value Like "Earn Manual*" Then
If .Offset(6).Value Like "Avg*" Then ' shows AVG, negative value
UnionRange rUnion, .Offset(8)
Else ' no AVG, negative value
UnionRange rUnion, .Offset(5)
End If
Else
'This can't be right
If .Offset(6).Value Like "Avg*" Then 'If Like "Avg*" Then Delete These Cells
UnionRange rUnion, .Resize(3)
UnionRange rUnion, .Offset(5)
Else 'Hell If Not Like "Avg*" Then Delete The Same Cells Anyway
UnionRange rUnion, .Resize(3)
UnionRange rUnion, .Offset(5)
End If
End If
End With
Next
End With
If Not rUnion Is Nothing Then
Application.ScreenUpdating = False
rUnion.EntireRow.Delete
End If
End Sub
Sub UnionRange(ByRef rUnion As Range, ByRef Cell As Range)
If rUnion Is Nothing Then
Set rUnion = Cell
Else
Set rUnion = Union(rUnion, Cell)
End If
End Sub
