Can I clean a hot tub filter with vinegar?

Using professional tub cleaning services will of course bring the best results for your needs. However, the bathtub is frequently contaminated with hair and other matter when you soak in the water. Therefore, the cost of professional service will be very high and difficult to do regularly, so the handmade hot tub filter hacks will be a great solution.

There are many ways to clean the bath at home, one of which is to take advantage of the ingredients that are always in your kitchen: vinegar. You can use this excellent cleaning agent to clean your bathtub as well as some other areas of your home. This hack is widely used as a quick and convenient homemade solution.

Why vinegar? Vinegar is a safe and friendly cleanser. Its acidity of about 2.5pH helps to remove dirt effectively, especially in narrow spaces. When you rub the vinegar into stains, the charged molecules in the vinegar absorb the positive and negative charges in the water, making stubborn stains go away easily.

The reason vinegar becoming popular is that its cleaning performance is superior to the price. In terms of dissolving scale, vinegar is safer than muriatic acid. In disinfectant terms, it is also safer than bleach. It has no foam ups or leaves any residue in the filter. Also, it is not expensive, easy to find, and always available in your house.

However, vinegar is not as great and perfect as industrial cleansers. Since vinegar is a weak acid, special substances, such as nasty biofilm that are in the tub’s pipes, can’t be washed off by vinegar. On the contrary, it can even damage your pipes. In this case, always use a hot tub flush on the plumbing.

Cleaning a hot tub’s filter with a dishwasher detergent is another safe option besides vinegar. It helps you to eliminate oil problems or residue very well.
