What to use (and what to avoid) to not damage the finish
For routine cleaning, it is recommended to use water, neutral liquid cleaners, and soft cloths or non-abrasive sponges, always avoiding scouring pads that can damage the tray’s surface. It is important not to mix different products during cleaning.
Avoid especially (for safety and to protect the finish):
- Abrasive sponges or steel wool
- Mixing products
- Very harsh chemical products (regular use)
Tip: If you are going to try a new product, test it first in an inconspicuous area.
How to routinely clean an Acrystone® resin shower tray
After each use, a cleaning with water should be done, and good ventilation of the bathroom should be ensured.
For the routine cleaning of the resin shower tray, it is recommended to use water, neutral liquid cleaners, and soft cloths or non-abrasive sponges, always avoiding scouring pads that can damage the tray’s surface. It is important not to mix different products during cleaning.
Additionally, as part of shower tray maintenance, the grid should be cleaned periodically to avoid soap or limescale buildup. To do this, remove it from the tray and clean it with a specific product for stainless steel.
If you use hair dyes, rinse the shower tray with water and soap once you’re done showering.
How to clean limescale from the shower
Periodically, we must clean the limescale buildup from our shower. Specific household anti-limescale products, along with the following steps, are the solution to how to clean limescale from the shower.
- Remove the drain grid and apply anti-limescale with a damp cloth all over the surface of the tray.
- Leave the product to act for 15 minutes. After this time, rinse with water.
- Place the grid back in place and rinse the tray again.
Tip: In dark trays, limescale is more noticeable. If you rinse and dry after the shower, you reduce marks significantly.
How to clean mold from the shower
Cleaning mold from the shower tray or tiles (if you have them) is vital for maintaining hygiene and good health in your home. Baking soda might be your best ally if you follow these steps:
- Pour 1/4 cup of warm water plus 3/4 cup of white vinegar into a bottle, and add 3 tablespoons of baking soda. Now shake vigorously to mix the solution.
- Next, apply it directly to the mold stains and let it sit for half an hour.
- After this time, scrub the stains with a toothbrush or a non-abrasive sponge, and rinse with plenty of hot water.
- Finally, open the windows to let your shower tray dry.
If, despite cleaning the tiles, there is still mold on the walls, the shower tray or the bathtub, it could be a problem caused by lack of ventilation. Therefore, to prevent moisture and mold, it is essential to ventilate the bathroom daily. This is because when we shower, the air condenses, and if this phenomenon is not released, it can settle on the ceiling, walls, bathroom furniture, and other elements, which can lead to the appearance of fungi, mold, and bacteria.
Remember to ventilate the bathroom daily to prevent mold from appearing again, and in addition to periodic cleaning, don’t leave the shower with water residue for an extended period.
However, if, regardless of its effectiveness, you want an eco-friendly answer to how to clean mold from the shower, opting for a solution of hot water, lemon juice, and vinegar can also work.
Important: If the black stain is in joints/silicone, it is usually mold. If it is on the surface, it is often a buildup of limescale + soap + dirt. Identifying it helps choose the correct treatment.
How to remove persistent stains from a resin shower tray
Regardless of its color, although the material is developed to avoid stains, sometimes a more specific cleaning beyond routine maintenance is required.
One of the most common questions in this regard is “how to clean yellow stains from the shower tray”. A home remedy to remove that annoying yellowing is using half a lemon with salt to rub the stain and rinse.
Some say yellow stains disappear by rubbing with brillo with a cloth soaked in a mixture of two teaspoons of salt and half a cup of turpentine. But from mcbath, we do not recommend using such abrasive products for maintaining our shower trays.
If you have doubts about a specific stain, it is safest to try it first in an inconspicuous area and avoid aggressive friction.
How to remove leftover tile adhesive or mortar after installation?
After the tray is installed, there may be remnants of tile adhesive or mortar. To remove these possible materials, use a joint descaler or grout remover, and also avoid rubbing directly on the tray to avoid scratching it.
This point is key after a renovation: better a specific and controlled product than "scratching" or insisting with scouring pads.

How to clean a black resin shower tray?
The black resin shower tray requires specific care to maintain the material's aesthetics like new.
Due to its color, in black resin shower trays, limescale can be more visible. Therefore, to completely eliminate dirt and stains, it's advisable to clean it frequently.
Option 1: Neutral soap
This is the least aggressive option, sufficient for the periodic maintenance of a black resin shower tray.
Apply neutral (non-abrasive) soap to the surface and leave it for 5-10 minutes to take effect.
After this time, take a soft sponge or damp cloth and wipe over the areas where the limescale is present.
Then, it's important to ensure that no soap residue is left on the surface, as its presence could damage the resin shower tray material.
Option 2: Water and diluted acetone
If the stains on the shower tray are caused by hair dyes, this is the most effective option.
Dilute acetone in water (1:3) (1 part acetone and 3 parts water) and mix the components without shaking. Once mixed, pour the liquid onto a damp cloth and wipe over the stained surface.
Next, leave it for 5-10 minutes and rinse with plenty of water.
After rinsing the shower tray surface, dry it and ensure that no residue of the mixture remains. This helps to prevent the resin shower tray from losing its material properties.
Recommendation: Try it first in a less visible area and don't use it as routine cleaning, only for specific stains (dye).
Option 3: Lemon or white cleaning vinegar
This option is effective against limescale and rust stains.
First, ventilate the room where you're cleaning due to the odor of the white vinegar.
Next, prepare a mixture containing:
-
The juice of two lemons.
-
Two cups of white cleaning vinegar.
For both, mix (1:2 water). After applying the mixture to the black resin shower tray, let it rest for 30 minutes to achieve complete stain removal.
After this time, gently wipe with a damp cloth (without scrubbing) and rinse the surface with plenty of water and soap.
Depending on the condition of the shower tray, these proposals for cleaning the black resin shower tray will be more useful. However, this last advice is generalized:
Under no circumstances should abrasive chemical products (ammonia, bleach, or hydrochloric acid) be applied to the surface. They can damage the finish and age the appearance of the shower tray, even leaving permanent stains.
