The bathtub in the home is what we use every day. Its cleaning is related to our health. Therefore, in order to ensure our health, cleaning and maintenance become what we have to do. The bathtub has different materials. Different materials require different methods. The bathtubs on the market can be divided into three categories, acrylic bathtubs, steel bathtubs and cast iron bathtubs. Then we will take a look at the different maintenance methods for these different materials.
Steel bathtub: not easy to fade, gloss can last, easy to clean. However, the steel bathtub has poor thermal insulation properties and is not resistant to impact. In general, it is better to use a neutral detergent or soap and water to clean the bathtub. Avoid using detergents for tiles or enamel surfaces, and it is best to clean them once a week to ensure that the bathtub stays dry after each use. Use a soft cloth or a good sponge to clean the bathtub. Don't leave metal objects in the bathtub, they can rust the bathtub and stain the surface. In addition, the use of soda powder to eliminate dirt is good.
Acrylic Bathtub: Acrylic plastic bathtub is light in weight, does not rust, will not be eroded, feels warm, can maintain water temperature for a long time, and is easy to wipe clean. This bathtub is currently the mainstream product on the market.
When the bathtub is being serviced, you can choose a suitable polishing machine, a 1900 rpm model wool polishing disc, apply the wax on the polishing disc, and then polish the polished part. Before sanding, the surface should be sandpaper repaired, repeated several times, and finally reach the shiny surface. You can use turpent water to clean the gelatin that is stained on the bathtub. Many chemicals can cause the acrylic to lose its luster, such as the water. It is usually only necessary to clean with No. 1 cleaner. Do not use corrosive detergents.
Polishing wax is made of high quality products. It can be polished with car. For small area, small or small, it can be manually polished. After grinding with 1500 water-resistant paper, use the surface polishing agent to repeatedly turn the circle to make the surface bright and even Toothpaste can be used instead of abrasives, but the grinding time is much longer. The surface of the large brand acrylic bathtub is specially treated, which is more resistant to abrasion than ordinary acrylic bathtubs. If the surface is accidentally scratched, if the scratch is light, use a toothpaste and a toothbrush to lightly brush it; if the scratch is deep, it is recommended to consult a professional and ask a professional maintenance person to handle it.
Cast iron bathtub: The cast iron bathtub is a very heavy and long-lasting material. The enamel on the surface is generally thinner than that on the steel bathtub. When cleaning the bathtub, you can't use the cleaning agent containing abrasive ingredients. The disadvantage of this bathtub is that the water will quickly The ground is getting cold, and the shape of the cast iron bathtub is usually cumbersome, expensive, and not very good. But its advantage is that it has a long service life.
The bathtub can be cleaned with an acid-free cleaner and a non-abrasive soft foam pad can be used to clean the dirt on the non-slip surface of the bathtub.
Cast iron bathtubs are the most susceptible to scratches. If there are rust scratches, remove the rust spots with the decontamination powder, wipe with a dry cloth, and finally apply the special adhesive for the bathtub. The scratches will not enlarge. The bathtub must be cleaned with a sponge and washing powder. It cannot be brushed with a brush.
