Use a product called "KILZ" that you paint over it then repaint the ceiling .If you do this in the right order it will not come through. Just paint it and it will always bleed through over time.

Best Answer: Bleach will only remove a small portion of the stain and the scrub brush on concrete will definitely cause permanent damage to the concrete. Once concrete is "spot treated" with improper tools, chemicals or techniques it can be permanently damaged. Battery acid stains are not rust and are a chemical reaction within the concrete.

If you try Hydrochloric Acid, Hydrochloric will only remove a maximum of 60-80% of the stain. It is very dangerous and will permanently damage your concrete. The only reason HCL Acid works is because it dissolves the cement past and takes a small amount of stain with it. Fertilizer stain are not created equal and you need something that works, every time.

The solution we know will work is a new product called F9 BARC (Battery Acid Restoration Cleaner) made by Front 9 Restoration, Inc.

Answer #2

spray concrete which is rich in cement and pure water in surface level which will avoid rust appearance or can use acids(like vinegar or other) as spray where ever rust appears

In order to remove rust stains from car paint, you will need to buy rust removing acid. This acid needs to be applied to the affected area. It then needs to sit for about two hours and eventually be removed with a wet sponge.
