All the ideas here I have tried myself so I know they work. If you like all natural products here are some ideas.
1 Tbsp. Baking soda
1 cup water
1 small spray bottle (you can get these at a discount store)
Mix until soda dissolves. Spray on wet hair and wash like you would with regular shampoo. Your hair should be squeaky clean.
1 Tbsp. Apple cider Vinegar
1 Cup water
1 spray bottle
Mix well, then spray on hair. Your hair should feel silky. Rinse well and towel dry. No more tangles and the smell of vinegar will dissipate.
Mix 1 part vinegar to 5 parts water.
Use waded up newspaper to wipe with.
Gets the windows clean with no streaks.
