Prosharp has now gone International with our sharpening and repair service with our first shipment of instruments being returned to a customer in New York and a large amount of work to begin from the UK.
We have been selling instruments overseas for quite a while. It's exciting times.

Quite a lot of instruments are coming into our premises for repair and sharpening that have a problem with hinges sticking stopping them from working properly. We have worked out that the problem is coming from a build-up of residue in the hinges. This residue is from the detergent used in the Ultrasonic cleaning machines.

If you have the problem the first thing to do is to make sure that the correct amount of detergent is being used. If too much detergent is being used the outside of the instruments will usually also go a slight brown color which we call tea staining.
Once the instruments have been washed and come out of the ultrasonic cleaner they then need to be rinsed and the handles moved under water to remove the detergent from inside the hinges. It is this detergent on the hinges that is causing the problems. There is a brown build up in the hinges that build up over a period of time and gets thicker from the detergent being cooked in the autoclave over and over. It happens quicker to the better quality instruments as they have tighter hinges to start with.
We have a product on our online store called “LOOSEN UP” which is used to dissolve the build-up and improve instrument function.

WARNING normal oil should not be put on the hinges as this can also cause further problems.​
