Read the package, all info should be there including how to contact Safer. This is a fine product.

What they shipped me was junk. There were globs in the bottle. Not a liquid spray. Unusable.

It does take out rust. Use gloves and scrub hard. Use it all the time on my stainless sink.

No. Rust is caused by a fungus. This product contains imidacloprid which is a systemic insecticide, absorbed through the ground or the surface of the plant. It has no activity against fungi, to my knowledge. Works great against pine bark beetle and spruce scale , both major evergreen killers in my part of the country.

If there is a lot of rust, first try to dissolve the rust with CLR. Then use the polishing creme. I don't think the polishing creme would take off serious rust. It will, however, polish metals to a beautiful luster.

Yes it works well. You just have to sand off the chunks of rust first then spray this on. I used it for the bottom of my car.

Yes, it does and that's pretty nasty stuff, so be sure to carefully follow all safety warnings. The msds is at http://www.whink.com/cmssites/ws0811www.whink.com/uploads/Documents/Rust%20%20Stain%20Remover%201204031.pdf

Silicone spray or rag treatment will prevent light rusting. Otherwise no damage when left outside over extended duration, in above freezing conditions.

I do not know. I have used this product only on ferrous metals and have not tried it on any stainless steel alloys. This product will remove rust, but it can not keep it from coming back. The area where the rust is removed will look clean but needs to be sealed to minimize the return of oxidation, maybe a high temp cooking oil thinly applied to the effected area could serve this purpose. good luck.

It will remove surface impurities. If you have some light corrosion or tarnish on the outside, then yes, some heavy polishing will take care of it. If the level of oxidation is too high, then the rust will have eroded and made pits in the metal. There is no helping that level of damage short of grinding away the surface completely.

I have used this product on various projects. To get the best results, you should remove any excess material (loose and flaking rust, peeling paint, etc.). You can just apply it to any rusty spot and help interrupt the rust cycle. If you have too much material over the base/core rusty metal, it may not react to halt the on going rusting action.

I agree with the previous responder. I would be careful using something that aggressive on the finish. Have had great results with Bar Keepers helper when nothing else worked...particularly around rust.

My limited knowledge of Copper Sulfate is: - it's more toxic than the active ingredients in Roebic and can effect surrounding trees as the roots can uptake this stuff into the main part (systemic). This stuff kills just the roots, more topical. I use copper sulfate (blue crytsals) dissolved and dilluated in a spray to remove lichens and moss on my shaded shingles in N. WI. Works like a charm, but becareful where the downspots go, kills everything it comes in contact with.

I used it to get the rust out of my Harley Davidson gas tank so it should work on the rack, but you have to soak them over night.

I believe it works on rust. I have a new home and purchased this to eliminate Clacium and metals. If you research this product I believe you will find it deals with all metal in the water.

Hi Valerie, I don't know if it will remove rust. I have very soft water and I love the shampoo. I think it's worth a try.

It doesn't remove moisture from the air . It warms the air inside and creates air currents which prevent condensation from forming on the steel. Thus preventing rust. Like when you bring a firearm inside in the winter, moisture will form on the steel. This is just the opposite, preventing condensation from happening.
