Do these come with the spray top?

No. The product is paste like so it isn't something that will spray. Goes on more like car wax. It is the best hard water spot remover ever!

Will this product remove yellow stains from my shower due to well water?

Do NOT add any water to the product OR on the surface that you are cleaning. Use straight from the bottle and apply directly to the surface needing to be cleaned. Use a clean dry cloth to remove the product AFTER you have used the included brushes or brushes of your own. Then, wash or rise with water. You will be amazed! I have done my kitchen sink hard water stains, 3-toilets, 15+ windows and all have come out super clean and beautiful. Like I mentioned before, I used only my finger tip to clean the first window and the product worked perfectly. The drill shafts are quick release and are short.

What are the ingredients?

i do not know. the website nor the bottle has the ingredients broken down in layman's term unless you know what LAS complex is. bioclean also has surfactant and silica flour which i believe has little to do with the cleaning power. the bottle does say it is non-toxic; eco friendly and biodegradable. it is manufactured in California and has no cancer warning labels on it.

Is this product really as good as advertised?

I believe it is. I was introduced by a glass company that had come to Ck my gas fireplace. The glass was dark and he used this product to clean the glass. It was really amazing. So he gave me a bit of it and I ran in and used it on my shower door. Amazing again. I have not had an issue with the product scratching. Now my housekeeper uses it in her other clients homes. It’s a great product for my uses.
