glasgow Posted May 27, 2015 Share Posted May 27, 2015 I Need to clean some dust and tiny silicone parts off a K rover sump gasket. What should I use-Wynn's brake and clutch cleaner? could theis brake cleaner damage the thin "rubbery" coat of the gasket? Will the brake cleaner leave any residue that could have a harmful effect on the engine? Thank you in advance Ahmed Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted May 27, 2015 Member Share Posted May 27, 2015 Brake cleaner is prettty aggressive, and there's a big range of different constituents in different products. In general I'd keep it away from rubber and plastics. It's unlikely to leave a residue.What is the gasket made of?Could you post a photo of the affected area of the gasket?"Silicone remover/ cleaner" is available but I've never understood what it is.I wonder if petrol and a very gentle scrape might be the best method.JonathanPS: Did you decide to sort this out yourself after the garage's effort?

SM25T Posted May 28, 2015 Share Posted May 28, 2015 I would use a flat blade paint scraper (not the sort with a razor sharp blade) held almost flat to the gasket ..... or use a fingernail or rub it with my thumb. Link to comment Share on other sites More sharing options...
Nigel Riches Posted May 28, 2015 Share Posted May 28, 2015 Jonathan, the silicone sealant removal goo that I looked at in a local hardware shop was, as far as I could understand from the label, jellified sulphuric acid, so probably not good to get it near anything delicate, like our cars.

Member Jonathan Kay Posted May 28, 2015 Member Share Posted May 28, 2015 Thanks: agreed.But is that the stuff widely sold for domestic use?Jonathan Link to comment Share on other sites More sharing options...
Nigel Riches Posted May 28, 2015 Share Posted May 28, 2015 Didn't appear to be any restrictions on the sale of it, which given the paranoid 'elf n safty crew in NZ, I find strange, but then it may be a very low percentage of acid. Nigel. Link to comment Share on other sites More sharing options...
glasgow Posted May 28, 2015 Author Share Posted May 28, 2015 I dont really need a silicone removal as I managed last week to remove all the "adherent" silicone off the edges before it get hardened. What I have on the gasket now is just some "loose" tiny silicone particles (topped up with some dust after beeing setting in the garage for 1 week). If I just use any thing to wipe the oil off the gasket, these dust and silicone particles will be wiped down. So, basically an oil cleaner or degreaser would do but not sure what to use? or may be washing with Pril in the kitchen sink (Gasket is a K rover, metal gasket with a thin rubbery surfaces) Link to comment Share on other sites More sharing options...
David Brown Posted May 28, 2015 Share Posted May 28, 2015 Use Isopropyl Alchol or just Fairy Liquid. Link to comment Share on other sites More sharing options...
