Put the lavender, rosemary, and vinegar in a clean glass jar. Cover the jar with wax/greaseproof paper and put the lid on.
After a couple of days, check the jar to see if you need to top it off with more vinegar.
Let the mixture infuse in a cool, dark place for one month, and then strain out and discard the herbs.
Put the strained vinegar, hot water, liquid soap, borax, and baking soda into a spray bottle. Shake until the minerals dissolve.
Shake before spraying and use to clean your house.
