My homemade brush cleaner recipe works for any cleaning schedule since it makes enough solution for soaking sessions (my preferred method of cleaning) or daily spraying. Whichever method you choose, go with something that’s doable for you.
Update: I don't use a nourishing oil in this solution anymore. It's just one less step and ingredient. I also make just a small amount of this solution. Enough for a one-time use. At this point, I eyeball the amount needed.
