Wuerth - 0890200011045 1 Rust Remover (300 g)

Good product and it is worth the amount of its price. I have used it on many rusted materials and it is very effective in loosening the rusted parts esp on latches , nuts and bolts and also it has been proven very effective on good oily and sticky surfaces where lot of dust sits and you just need to spray and wait for atleast an hour or 2 to get the greasy part released. This I myself have personally seen. I recommend to buy this.

I am using this product pretty frequently. Initially, I was doubtful about the product usefulness and quality of the product. However, within first few uses, where lot of rusty material was involved, it became apparent that the product works as claimed.The rusted hinges became free and operational within minutes, the rusted locks became free within minutes when sprayed with this product. Not only that, all such material that was cleaned using this spray went through a complete monsoon session and kept working smoothly.One caution though - even by mistake do not spray or drip residual product from spray pipe, on wood ply, wooden planks or wood material. The wood material starts looking like burnt wood within minutes In my case, the ply material bubbled as if heated with high flame.I do not think this information was mentioned on the can and hence 4 stars.

Very useful

Rust removing capability is effective,But while doing that can damage paint.

I sprayed it for my dominar, as I had few rusty nuts, rods or metal parts here and there. Used it on them, and it served well to remove the rust. Post removal, I applied black paint. Did the job well.

The media could not be loaded.

Product is very good,40% of the chain of my bike was affected by rust when I purchased this and now it is like a new chain again. Just apply the product properly and leave it for 3-5min and then get steel brush(kitchen one will do) and rub it well in the affected area and you will see all rust is just vanished and lube your chain after that.

Easy to use, really effective...
