Are there other places that have diy recipes that are safe to use?
That’s the spot. You won’t likely find many other recipes outside of there, here, and reddit, although there are very few here or reddit, and those that you do find will likely be from before the DIY site came about. It will be up to you to determine if the recipe is safe, regardless of where it’s found.
No need to start a new topic every time you have a question. Just find an already existing topic.
