Our tool protection oil is 100% pure silicone oil, great for tools but also hypoallergenic, cosmetic grade that is safe and non sensitising for hands . The clever bit? Our silicone oil is sprayable using the manual pump action bottle. This allows us to keep it pure – additive and solvent free. Originally specified for easy coating and protection of metal and plastic tools alike our silicone oil spray has proved its worth in applications as diverse as acrylic pour painting, watch and clock repair, air rifle maintenance and coating guitar strings.

Dishwasher Spanners! We created our first because our own dishwasher salt compartment would regularly get stuck on our Siemens dishwasher. After grappling, hammering and swearing, usually surrounded by dirty dishes, we set about designing and 3D printing a tool that fitted. A few days later the dishwasher spanner was born:
The Original Fits most Bosch and Siemens Machines code DWSS1
Having made something that worked, frankly, far better than our highest expectations we made a few more for friends and family to try before putting them on our Amazon shop.
That was over 2 years ago and we now have hundreds of happy customers all over the world. We have streamlined and strengthened the design a little to make it easily postable and developed two other models so we now cover most of the common types of dishwasher salt cap.
They work so well because they spread the load and give a big mechanical advantage. We 3D print them from eco-friendly PLA making them light, durable and easy to handle.
A few reviews, just because they make us happy:
“Opened the bosch cap in seconds, after I had been battling it for hours.“
“Delighted to have found this little tool which did the job easily and saved the expense of a service call-out. My salt dispenser was stuck fast…note to self, do not overfill!!! Money well spent.“
“I don’t often leave feed back for every day items but this device is EXCELLENT in every way including the quality of manufacture. The salt dispenser cap in our Bosch has always been such negative feature, one almost dreads the top-up light coming on. Not any longer! Frankly the machine should be supplied with one. Thank you!“
“An excellent product. My salt cap had been stuck and ummoveable because the dried salt had welded it shut. The spanner opened it in seconds!!“
“Works as described – excellent. Saves trying to get both hands down into the side of the dishwasher and turning the cap with both hands!!“
“I had despaired on being able to remove the dishwasher salt cap. It is very awkwardly located and very difficult to get any sort of purchase on the cap to remove it. The spanner was an absolute godsend. Worked instantly. Don’t stint yourself – if you can’t remove that pesky salt cap, get the spanner.“


You can buy the salt spanners from our Amazon and Ebay shops. We ship worldwide with Royal Mail International Standard. If you are not sure which one you need please drop us an email with your dishwasher model number
We can also design and manufacture similar tools to your requirements so if you have a cap that does not, as it were, fit, then let us know!
