Customer Reviews for Formula 88 1 Qt. Rust Stain Remover

When I went to use it, the sprayer was broken. I ended up pouring the product on the rust stains on my concrete patio. It worked very well. I will buy it again.

I bought this product to remove some rust on the paint of a box truck that I had purchased. I wish I would have taken before and after pictures.....this product worked great. Unfortunately the product also took the finish off of my Apple Ultra watch. My sprayer did not work well at all. I highly recommend this product for taking rust off.

It worked great on several things

It did not do the job.

Easily removed red clay stains that had been on siding for years

The product did not work well at all. The next time I tried to use it the trigger would not function properly.

in the description it says can be used on vinyl. then when you get the product home, on the back of the bottle, it says do not use on laminate. to me vinyl and laminate are pretty much the same thing. how can they mislead people like that. it didnt work anyway, i tried it. didnt hurt anything, but was like spraying water on the stain.

This product works as great as the original Formula 88. I always have some on hand.

Great product worked immediately!! Highly recommend this product!!

Did exactly what it was suppossed to do!

Followed directions and it didn’t work at ll

Was using this on concrete that had rust stains on it from rebar. Stains that were a year or 2 were removed on the first usage. Had some stains that were 4 or 5 years old, and after spraying on a couple of times, most the stain was gone but not all. I think this is a good item, just don't expect miracles.

Slightly lightened the rust stains on concrete, but didn't remove them.

Exceeded expectations.Will order large refill.

This product worked exactly as stated before I purchased it. I had some bad rust stains on concrete. We followed the directions and used just a stiff not metal type brush and to our amazement the rust disappeared before out eyes. It did not take much from the bottle either. 10 star product. Cliff

Excellent, removed rust stains easily from our new, smooth finish concrete patio
