I’ve been experimenting with homemade cleaning supplies lately. Here are some recipes I have been working with, mostly from the internet with some modifications.

Dishwasher Detergent
2 tbsp borax
2 tbsp baking soda

for rinse cycle, 2 tbsp citric acid (I suppose you could use vinegar too)

Furniture Polish
1 L of water
2 tbsp of olive oil
2 tbsp lemon juice
mix, use damp cloth on furniture then buff with soft dry cloth

General Cleaning Mix
1 tbsp of borax
1 tbsp of baking soda
drops of lavender and orange essential oil
