Yes. Our Brilliant Bath is safe and effective on the glass only (avoid any contact with the frame, trim or track of the door, as these are usually made of aluminum) part of a shower door. The best way to apply it to the glass is to spray some Brilliant Bath into a damp cloth or sponge and apply it to the affected stained areas of the glass. After 2 minutes, take a clean sponge/cloth and clear cold water to remove the solution. Do not spray the doors as you will get the product on materials it's not intended to be used on.

Yes. You can use Brilliant Bath on vinyl siding as long as it is diluted and is thoroughly rinsed off of the surface in under two minutes. Studies have shown that the top coating of the siding will be affected if full strength Brilliant Bath is left on the surface for five minutes or longer.

We recommend using a cotton ball or soft cloth for the best application. However, dipping smaller items (such as sterling silver jewelry) may be easier. It is important to rinse with cold water IMMEDIATELY and do not let Tarn-X dry. Never keep Tarn-X on an item longer than a maximum of two minutes.

No, Brilliant Bath should not be used in the washing machine or dishwasher. The detergents in the product may foam excessively when agitated.

Only if the shower enclosure does not have a synthetic coating on it. Be sure to test a small, hidden area before cleaning the entire shower and wipe dry to check for any adverse effects.

Yes, Brilliant Bath is great for cleaning pet bowls from food grime and water deposits! Spray Brilliant Bath to affected area of ceramic, stainless steel or plastic bowl.
