Identifying Your Bathtub Material

Identifying the material your particular bathtub is made of should be a TOP PRIORITY before scrubbing away at your tub. This enables you to know which techniques are best to clean a bathtub, depending on what it’s made of.

So, before we run through the basics, allow us to lead you through identifying your tub material first!

Porcelain Bathtubs

Porcelain bathtubs are a popular choice due to their classic elegance and durability. They typically have a glossy, smooth surface that’s easy to clean and maintain.

They’re often white or off-white, though other options are still available. The smooth, glass-like finish gives them a luxurious and pristine look.

Acrylic Bathtubs

Acrylic bathtubs often have a high-gloss finish, similar to porcelain, but may come in a broader range of colors and styles.

They can mimic the look of other materials like stone or metal, offering more design options for your bathroom. They are lightweight compared to porcelain or cast iron materials.

Ceramic Bathtubs

Ceramic bathtubs, also known as ceramic-coated bathtubs, are another common type of tub material. They have a smooth, shiny, and glossy finish, resembling porcelain.

However, ceramic coatings may come in a wider range of hues and patterns, allowing for more customization options.

Fiberglass Bathtubs

Fiberglass bathtubs have a smooth and slightly glossy surface but may have a slight texture or feel grainy. The surface finish is typically uniform and may have a slight sheen.

One of the critical characteristics of fiberglass tubs is their lightweight construction. Fiberglass is a flexible material, so you may notice slight bending when applying pressure to the tub’s sides.

Cultured Marble Bathtubs

Cultured marble bathtubs are a luxurious and visually appealing option that replicates the look of natural marble but comes at a lower price.

They often feature intricate patterns and veining, creating a premium aesthetic. The tub’s surface is smooth and polished, similar to natural marble.

Maintaining the white shine of your bathtub requires a bit of elbow grease. By following these maintenance tips, you can preserve the whiteness and cleanliness of your bathtub with minimal scrubbing:

  1. Regular cleaning routine – Establish a cleaning routine to prevent dirt, blemishes, and soap scum buildup. Deep clean a bathtub with a few drops of dish soap and an old toothbrush.
  2. Rinse after each use – Rinse your tub with hot water to remove any soap scum, shampoo, or body oils that can contribute to stains and discoloration.
  3. Wipe off excess moisture – After rinsing, dry the surface of your tub with a clean paper towel or microfiber cloth. This helps prevent water spots from forming, keeping the white shine intact.

  1. Use soft water – If you have hard water, consider using a water softener or a water filter to reduce mineral deposits that can cause discoloration and buildup. Hard water solutions can create toxic gas or noxious fumes.
  2. Avoid stain-causing substances – Avoid using products that can cause blemishes, such as hair dyes, strong dyes, or heavily pigmented bath products.

Precautions to Avoid Damaging Your Tub

Taking precautions while cleaning and using your tub is essential to prevent damage. Here are some precautions to keep in mind:

  1. Read the manufacturer’s instructions – These instructions often provide recommended cleaning methods and products and any specific precautions to follow.
  2. Avoid abrasive cleaners and tools – Avoid abrasive cleaners, harsh chemicals, or scrubbing tools that can scratch or damage the surface of your tub.
  3. Spot test new products – Before using a new cleaning solution, perform a spot test on a small, unnoticeable area of your tub.
  4. Ventilate the bathroom – Ensure proper ventilation by opening windows or turning on the exhaust fan while using cleaning products.
  5. Use suitable tools – Select appropriate cleaning tools for your tub material. Avoid using a rough or abrasive scrub brush, steel wool, or scouring pads that can cause scratches.
  6. Be gentle with fiberglass and acrylic tubs – If you have an acrylic or fiberglass tub, be extra cautious and avoid using abrasive cleaners or tools.
  7. Avoid extreme temperatures– Avoid using cold or warm water directly on your bathtub’s surface. Rapid temperature changes can cause thermal shock and potentially lead to cracks or damage.
  8. Proper drainage – Ensure proper drainage by regularly clearing any debris or hair that may accumulate in the bathtub drain. This prevents clogs and potential water damage.
