If you love cleaning, you understand the incomparable feeling of smelling the fresh scent of lemon around your home. It’s simply satisfying to see a stack of spotless dishes and a freshly cleaned bathroom. It’s even more relaxing when you have that citric smell lingering in the air. It’s no wonder why many people stock kilos of calamansi to add to their natural cleaning products.
Now, if you want to learn tips for cleaning with citric acid, you’ve come to the right place. Today, we’ll show you how you can use this product descale surfaces, deodorize appliances, and even sanitize kitchen items.
Why Should You Start Cleaning with Citric Acid?
Citric acid may not be a staple in the average Filipino’s collection of cleaning materials. Even so, it has long been used as a household disinfectant and cleaner because of its efficiency as a chelating agent.
Chelation involves forming a bond between the molecule and metal ions. Because rust and hard water stains contain metal components, citric acid binds the metals and breaks up their materials. Consequently, these stubborn stains dissolve easily in water.
To put it simply, lime and calcium in hard water bind to citric acid. Certain cleaning products contain this ingredient. But if you use the compound in higher concentrations, you can get rid of mineral deposits on appliances and surfaces.
According to the U.S. Environmental Protection Agency, citric acid is generally safe to use. However, be careful when using this compound because you’ll be dealing with it in powder form. Without proper protective gear, you might breathe in the dust and experience throat and nose irritation. Before handling the product, wear high-quality rubber gloves, mask, and eye protection.
