7. 5 Cleaning and Maintenance Tips for Solid Surface Bathtubs
Maintaining a solid surface bathtub is essential to keep it looking pristine and extending its lifespan. With regular care and proper cleaning techniques, it’s easy to prevent damage and maintain the bathtub’s elegant appearance. Here are some practical cleaning and maintenance tips for solid surface bathtubs.
#1 Use Non-Abrasive Cleaner
To clean the bathtub, it is recommended to use a non-abrasive cleaner, such as mild dish soap. These cleaners effectively remove dirt and stains without scratching the surface. For example, a non-abrasive cleaner preserves the smooth finish of a solid surface bathtub after a bath.
#2 Avoid Using Harmful Objects
Avoiding harsh scrubbers or abrasive tools on the bathtub is essential to prevent surface damage. Instead of metal scrubbers, a soft sponge should be used to clean the bathtub. Additionally, placing a trivet under hot items helps to prevent scratches and maintain the bathtub’s smooth finish.
#3 Applying Baking Soda and Water
To tackle stubborn stains, a paste can be created by mixing baking soda and water. The stain should be gently scrubbed with a non-abrasive sponge and then rinsed thoroughly. This method is particularly effective for tough stains such as soap scum or hard water marks.
#4 Use Heat Protection Pads
Placing heat protection pads under hot objects is essential to avoid damaging the surface. Solid surface materials can withstand heat but may get damaged by direct contact with hot items. But wait – there’s more using a heat pad under a hot curling iron prevents heat damage and keeps the bathtub looking flawless.
#5 Fixing Small Scratches with Fine Sandpaper
To fix small scratches on the bathtub, one should use fine sandpaper. For example, the scratched area needs to be gently sanded in a circular motion until it blends with the rest of the surface. This method is effective for minor scratches and helps maintain the bathtub’s appearance.
