Seller: awf-clocks (3,586) 100%, Location: Glossop, Derbyshire, Ships to: GB, Item: 252526709354 Antique clock concentrate cleaning fluid1 Litre Having worked in the antique restoration trade for some 20 years I have produced a non ferrous metal cleaning solution which removes old dirt and grease. It gives a kick start especially when restoring antique clock movements. The solution should be mixed to the ratio of 1 part cleaner to 7 parts cold water. Mix well and place in a suitable plastic container with a sealed lid (a clip lock box).The cleaner is ammonia based so precaution should be maintained when mixing as the fumes are harmful.!Good ventilation is a must! Items to submerged can be left for between 1 to 3 hours depending on how stubborn the dirt is but no more than 24 hours.A soft brush can be used to agitate dirt and then a rinse in warm water should do the trick.The cleaner can be stored and used a number of times. !!The best bit about this cleaner is the fact it does not harm original gilding!! Thanks for looking, please note we supply other products in our online store awf-clocks including high quality reproduction hands, cleaner and many other clock tools/parts for horological repairs. We also provide a restoration service for both clock cases and movements.Our website Please message for further details.
