Homemade baby wipes

I know there are a million and a half homemade baby wipe recipes/blog posts out there but I feel mine will be the best because of trial and error. lol
I have made several batches of homemade baby wipes and just got frustrated time after time because they would start to grow mildew and I'd end up throwing half the batch away which meant I wasn't saving the money that I'd made these dang things to save with! 
I recently dove back into my homemade baby wipe research after a lengthy break from making them and stumbled upon a tip that so far has made the difference between mildew and no mildew. 

Here is my most recent recipe/directions.

Ingredients & Supplies:
Airtight Container
2 1/4 cups water (This depends on the size paper towel roll you use - you may need slightly more or less.)
1.5 Tbs Baby Wash (your favorite brand/scent)
1 Tbs Baby Oil (generic works fine)
1 Tbs White Vinegar (supposed to inhibit growth of mildew)
1 Roll Viva brand paper towels 

Directions:
1. Bring water to a boil on stove top and allow to cool to room temperature.  This step is important as it removes the bacteria from the water thereby keeping your wipes from molding (the step that has made the difference this time around so there must be truth to this!). 

2. While the water is boiling, use a NON-serrated SHARP knife to cut the roll of paper towels in half.  Place one of the halved paper towel rolls cut side down in the container. You will use 1/2 of the roll for each batch of wipes. 

3.  Mix water, baby bath, and baby oil, vinegar.  

4.  Pour the liquid mixture over the paper towels and close with the airtight lid.

5. As soon as the liquid is cool enough, you can remove the inner cardboard. 

Notes: I use a tupperware bowl I already had to soak the paper towels in then when I remove the cardboard I put the roll into a left over wipe box I have. I have seen posts where people have bought tupperware in the size to fit the roll and pull them out from there but I already had a box to use so I am not going to waste the money. You can unroll and fold the wipes accordion style but I just unroll a few times and put it back in the box with the unrolled wipes on top so I have several that pull right through. I only have to do that once a day so it's no biggie. Also, i have heard good things about Bounty Select-a-Size brand paper towels so if they are less expensive I'll be trying those next batch. 

Please comment below if you have you make your own and do it differently or if you have any questions.
