Any advice please of removing a very hard carbon residue from the burner on an optimus 111? Trying to refurb this 111 but the tubes in the burner are so difficult to get into and around etc . Any advice / help much appreciated. Thanks , Jack
Thanks snwcmpr, I live in a small seaside town and given to many specialist places that might be able to do that, Do you know what sort of buisness's might do that sort of thing? Are garages likly to hove that sort of gear? Jack
@Jack Ryan an ultrasonic cleaner is not that expensive to buy and once you have one I'm sure you'll find plenty of uses for it. For example, cleaning your beloved's jewellery in addition to stove parts. You don't need a huge industrial grade one. Some people hedge their best and get larger ones anticipating having larger items to clean in the future. Mine has an 800mL tank capacity and cost me £28 from the bay of evil 3 years ago. As long as you can submerge the burner head in the tank it should suffice. Having a timer and heating facilities is nice but not essential. You can heat the water in a kettle before using and switch on and leave it for 30 minutes at a time. Start with water. Other solvents can be used but with care not to release harmful vapours or flammable gases into the work environment. If you are going to use solvents other than water put the item in a solvent proof container and lower that into the cleaning tank that contains enough water to transmit the sonic waves into the secondary container. Finally, don't stand over it in a shed or small room unless you have hearing protection. They can get pretty loud. Regards John
