Oxalic Acid 5% Solution Container Bleaching/Stain Removal/Rust Remover (1L Container)

I wish I had done a before and after. This stuff is legit! I had a bit black ring from a pan on our wooden top. Poured a tiny amount in a bowl and used a cotton bud to wipe around the area. Let it sit. Came back 30 mins later and it was completely gone

Very effective at removing black marks caused by tins left on worktop. I used a cotton bud dipped in the solution to trace the outline of the stain. I needed to repeat every half hour or so , after about 3 or 4 rounds all was good. Some soaked in water marks took more . I wished I'd taken before and after shots but I'm a very pleased customer.

No miracles

This was recommended to take the rusty marks from the expansion pipe of my upstairs neighbour but as you will see from the photos this acid cleaner did not work.

Worked well on getting Some rust marks off our patio and our kitchen work tops

Tried this on rust marks on my patio left by scaffolding and it worked really well.

No instructions what so ever came with the product, giving what this is this should have had some dilution instructions at least.

I found out later that I can buy crystals and mix them with water and it's much more cost effective, but there's nothing wrong with the quality of this product.
