​Our Toilet Coating (1 oz package) allows you to coat ~5 to 6 individual toilets. The Maintenance Spray can be used to renew the surface for at least 10 - 15 times.

Our Toilet Coating is compatible to all types of toilets and urinals that are made out of ceramic without any pre-existing coatings on them.

You can apply our spotLESS Toilet Coating in three simple steps:

• Remove the excess water in the toilet bowl.
• Clean the toilet surface thoroughly with a toilet cleaner or rubbing alcohol. Wait until the surface is completely dried before the coating application.
  
• Spray our spotLESS Toilet Coating onto the toilet surface. Roughly 10 - 15 squeezes would give all you need to cover the toilet surface. Alternatively, you can also spray the coating onto a paper towel and wipe the toilet surface uniformly. Wait for 5 minutes to cure, and you are done! Make sure you do it in a well ventilated environment, wear masks as necessary and wash your hands afterwards!

Yes, our Toilet Coating is compatible with regular toilet cleaners including multi-purpose surface cleaning, bleach, hydrogen peroxide-based cleaner, mild acid cleaner, and alcohol-based cleaner. We recommend using a soft cloth or a soft-bristled plastic brush to clean your toilet bowl. We do not recommend using metal scrub brushes or steel wool in cleaning the surface. We also do not recommend using polishing powders or cleansers that contain coarse particles.

We recommend you to clean your toilet bowl using a soft-bristled plastic brush at least once a week to remove the microscopic organic residues that are adhering onto the coated surface, followed by a few squeeze of the Maintenance Spray and apply it uniformly across the coated surface with a soft-bristled plastic brush. Your surface should be renewed instantly after the cleaning step.

Depending on your frequency of usage, we recommend you to renew the surface with our Toilet Coating once a month.

Depending on your frequency of usage, we recommend you to renew the surface with our Maintenance Spray once a week for home use, or once every two days for high frequency toilet usage in commercial settings or public bathrooms. 

​No. Our Maintenance Spray by itself has little self-cleaning effect. This spray is only compatible with spotLESS Home Collection Coatings.

Our spotLESS Toilet Coating can effectively prevent hard water stains build-up by >95% compared to other untreated surfaces.

Our spotLESS Toilet Coating, when fully applied onto a toilet surface, does not contain chemical components at a concentration level that are known to have a negative impact to the septic tank.

Our spotLESS Toilet Coating does not contain PFAS. Protecting the environment by reducing the use of aggressive chemicals and reducing our water footprint are among our key motivations for developing our spotLESS coating products. The main active ingredient in our coating products is silicone, which is known in the scientific literature to degrade naturally into silica, water, and carbon dioxide without negative impact on the environment. Silicone is also commonly found in toothpaste and cosmetic products.

The spotLESS Windshield Treatment is 2X as slippery as Rain-X, making it the optimal choice for repelling all sorts of unwanted material from your windshield. The Windshield Treatment can also be applied more quickly than its competitors. The treatment also possesses superior mechanical durability and long-lasting hydrophobic effects than competitors.

The Windshield Treatment is highly durable and does not degrade under direct sunlight for at least 2.5 years. Depending on the usage of the windshield wiper, we recommend to re-apply the Windshield Treatment at least once every 3 - 6 months.

Yes! The spotLESS Windshield Treatment is compatible with any regular cleaning that your car may undergo.

You can apply our spotLESS Windshield Treatment in the following steps:

1. Clean the windshield thoroughly with a regular glass cleaner, followed by rubbing alcohol. Wait until the surface is completely dried before the coating application.
2. Spray our spotLESS Windshield Treatment onto the windshield surface uniformly. Roughly 10 squeezes would give all you need. Alternatively, you can also spray the coating onto a paper towel and wipe the windshield uniformly. Wait for 5 minutes to cure, and remove haze using rubbing alcohol, and then you are done!
