HG rust remover

I’m genuinely impressed with this product. It removed rust stains quickly and effectively without damaging the metal surface. Very easy to use, and the results were visible almost immediately. I tried a few other products before, but this one worked far better. A little goes a long way as well, so the bottle should last quite a while. Highly recommended for anyone dealing with stubborn rust stains around the home or workshop.

I was scepticle but the feed back for rust removal was fairly positive. My requirement was to descale hot rolled mild steel flat bar brackets as a prep for priming and painting. Mill scale can easily be removed abrasively, grit blasting or rotary disc if you dont mind the resultant surface finish and cost. My method was by full immersion in an approximate 25% HG to water mix in a shallow polythen lined bath. That said, I can't vouch for painting the product on surfaces neat but I wouldnt have done it that way. The product is acidic so the usual PPE, gloves, skin and eye protection. The product does not fume or give off acidic smells. I allowed 24 hours for immersion. The solution did work and I washed the brackets down with a neutralising solution of Sodium Carbonate ( Soda Crystals ). Surface finish was back to original grey steel. The dissolved mill scale washes off as black smut. Mill scale removal is in excess of 99%. I have put the brackets back in the solution for another 24 hours to remove the odd stubborn spots caused by the laser profiling but overall they would do after 24 hours. The steel does not become etched and is not discolored by the solution. For me, 500ml for what is a small project has worked perfectly but derusting or descaling anything of size I would recommend grit ( sand ) blasting. I have seen the end result and once red oxide primed is a perfect method for gates railings, car parts, cast iron bench ends and the like. Hope this is a proper review for you.

This did an excellent job for the most part when items were dipped in a solution, just a few very heavily rusted items took a long time or needed doing twice. I did not use it for anything other than dipping.

I had tried everything to get rid of rust stains on porcelain graden tiles. ChatGPT actually recommended this product. It worked! Got rid of rust marks from plant pots. Wish I had done before and after photos! I diluted the solution and poured it on. In really stubborn areas I brushed it and left it for a few minutes. Every rust stain has gone!

I used it on metal that I had found whilst magnet fishing. I followed the instructions (although I might have diluted it more than you are meant to). I left it overnight and it did work to some extent but it didn't do a great job. In fairness, this might be because im trying to clean metal that's been in a river for god knows how long. Word of warning: it stinks. The liquid didn't smell but when I lifted the metal out (with gloves!) the smell was horrid.

Pretty good at cleaning light rust of metal when sent to soak in the water mix, I had no trouble with it coming into contain my skin, doesn’t give off any overpowering scent and can be used on all types of metals

Used on a rusty old radiator and it worked a treat. I used a paintbrush to apply it neat and kept checking it. once all the rust was wiping off easily I cleaned it with a wet cloth and polished it with a dry cloth. Good as new.

Easy to use. Does what it says on the bottle.

في الحقيقية انا اشتريت هاذا المنتج لان سيارتي يوجد بها صبع ويجب علي ان اصبغ سيارتي ثم قلت لنفسي ساجرب هاذا المنتج قبل الصبغ ، النتيجة لم اكن متوقها ، ازال جميع الصدأ الموجود في سيارتي بدون ان ياثر على صبغة السياره الاساسي ، انصحكم به وبشدة 🤙

Décapant puissant mais demande encore beaucoup de travail pour une finition impécable, voir acceptable!

Very strong and concentrated product. 1:5 with water strips off galvanising from bolts, as I found out by mistake.

استعدت لون الحديد وازال الصدأ بشكل كامل ، وضعت القليل منه على اسفنجة وقمت بمسح المكان الصدأ ، كانت النتيجة رائعة

Is doing the job
