Recently, we received a complaint from a customer who purchased a solid surface bathtub from Giving Tree Home. After about seven months of use, the customer noticed white spots, hazing, and uneven discoloration on the surface of the bathtub (as shown in the picture). This was the first time we received such feedback, especially for one of our best-selling models (UBS23PSBS1004W65), so we take this matter very seriously. But why did this happen?
The Root Cause of the Issue
The customer purchased a matte black solid surface bathtub from Giving Tree Home in April. About seven months later, the customer contacted us, stating that when they first used Lysol wipes to clean the bathtub, discoloration appeared, and the white spots could not be removed. We immediately requested clear photos and videos and forwarded them to our manufacturer's technical team for analysis. After an initial assessment, it was determined that the problem might have been caused by the use of an alcohol-based cleaner.
Although the materials and formulations may vary between different manufacturers, solid surface or stone resin are generally made from a blend of minerals (such as marble, quartz, limestone, etc.) and resin, which are then molded through injection molding. These materials themselves are not particularly sensitive to alcohol. However, dyes are often added during production to achieve a variety of colors. The issue arises when these dyes react with alcohol, causing the bathtub’s surface to lose its gloss, discolor, or develop water stains, whitening, or hazing effects.
Proper Cleaning Methods
Solid surface bathtubs are generally known for their excellent stain resistance and fade resistance, especially those with matte finishes. However, to keep your bathtub in optimal condition, regular cleaning is still recommended. Here’s the proper way to clean your solid surface bathtub:
Routine Cleaning
Use warm water and household dishwashing detergent. First, dampen the surface of the bathtub with water, and then gently scrub the surface with a soft cloth or sponge soaked in detergent. Make sure to clean every area thoroughly. It’s best to use a circular motion in a clockwise direction and avoid scrubbing too hard. After cleaning, rinse the bathtub thoroughly with warm water and use a clean, soft cloth to dry the surface.
Deep Cleaning
If the bathtub has been used for a long time, it is also a good idea to clean the drain. First, remove the drain cover, pour baking soda into the drain, and let it sit for a while. After it reacts, rinse it with warm water. Note that the baking soda should be poured into the drain, not onto the bathtub surface.
For Disinfection
Some users who prioritize skin health may be concerned about bacteria and may attempt to disinfect the bathtub using alcohol or disinfecting solutions. However, we do not recommend this. Solid surface bathtubs naturally have a non-porous surface and strong antibacterial properties. Normally, even after 10 years, the bathtub’s surface will not harbor bacteria. Therefore, simply following the cleaning instructions above will keep your bathtub clean and hygienic.
Dealing with Scratches and Damage
Over time, some homeowners may notice scratches on the bathtub’s surface. These are usually caused by hard objects. To prevent this, avoid using sharp or rough items on the bathtub surface. If scratches do occur, you can gently sand the area with 1500-2000 grit sandpaper to restore the surface.

Things to Keep in Mind When Cleaning Solid Surface Bathtubs
- Avoid using strong acids, strong bases, or alcohol-based cleaners, especially high concentrations of isopropyl alcohol or ethanol, as these will worsen the appearance of the bathtub.
- Do not use abrasive products such as rough towels or steel wool, as they can scratch the bathtub’s surface.
- Never use water that exceeds 140°F for cleaning. Using warm water significantly improves cleaning results.
- If you encounter stubborn stains that cannot be removed, please contact the seller for assistance instead of using unknown cleaning agents.
- When using colored essential oils or bath salts, first test to ensure the color will not stain the bathtub’s surface.
- If chemicals (such as hair dye) accidentally spill, clean them immediately with water.
- If the bathtub surface turns yellow after long-term use, it is best to contact the seller for professional polishing and sanding services, rather than attempting to clean it yourself.
Ending
Solid surface bathtubs are highly praised by homeowners for their long-lasting durability, but this longevity is based on proper cleaning and maintenance. Once again, we emphasize the importance of avoiding cleaning products with acidic or alkaline properties, as well as alcohol-based cleaners. If these substances come into contact with the surface, rinse them off immediately.
