Posted: Fri May 18, 2018 8:09 pm Post subject: Jenolite or other modern rust converters. |
|
|
I have had a white plastic bottle of the old Jenolite on my shelf for years and this week I had cause to use it.
It was nothing to do with cars but to treat some old imperial size manhole covers which were very rusty on the surfaces.
The "old" Jenolite worked well and converted the rusty covers to a surface suitable for repainting.
I presume the Jenolite I used is no longer available but can you please tell me if the modern equivalent is as good as the old or can anybody recommend another make or type which is effective.
The only available alternatives I saw in hardware shops today were labelled Hammerite.
Thank you. _________________ Starting Handle Expert

3 in 1 have a rattle can for that now, although it seems more like a waxy protection than a converter. |

Jenolite was and still is a phosphoric acid based rust converter, it's an expensive way of purchasing phosphoric acid, but convenient in the jelly form and of course no risk of splashing.

I can remember using liquid Jenolite to clean the gas plug on my SLR....[best not to forget the thing is soaking, either!!]

As I have said before Alasairq, I dismantled two carbs from the Bonnie I was restoring, popped the bits in phosphoric acid "just to give tham a couple of minutes".
The following day... all there was left in the botton of the container was a grey sludge!
(I learnt about restoration from that)

A good substitute for the jelly type is to soak the cheapest phosphoric acid you can get into cheap tissue paper laid onto a vertical panel or whatever. Laying it on with a brush in a similar way to how you might build up fibreglass with resin gives surprisingly good results. Works a treat for a fraction of the cost! |

Thank you all for your replies gentlemen.
You learn something new every day - I didn't know that Jenolite is merely
phosphoric acid and that is precisely what I will now buy. _________________ Starting Handle Expert

It's a few years now since I bought any but one of the best options for buying phosphoric acid used to be "milkstone remover" from the farm suppliers. |

I have sen Jenolite for sale and wondered if it was any good but I haven't tried it. I have used some of the "Bilt and Hamber" stuff; https://www.bilthamber.com/ not long enough ago to be able to say it's wonderful or anything but it seems good and they seem like a good company who are genuinely trying to make good quality products, so worth a look. Give me 5 years or so and I may be able to write a review |
