Diamond Celebration 1954 - 2014Tetrosyl Group is 60 years old and that means the iconic T-Cut brand is celebrating its Diamond Anniversary. To signify this milestone we commissioned an original 5ltr Tin to be encrusted with Swarovski Diamond Crystals by Shirley Sinclair of Crystallized By Request. The delicate work took 75 hours to apply 26,000 crystals to create this stunning masterpiece.

Peter Schofield Chairman of Tetrosyl said ....

After 60 years and tens of millions of Tins sold T-Cut is so iconic its virtually a verb, to remove scratches or clean paintwork most people say " Just T-Cut It " that's why we say it's the Cream of Britain.

In these days of manufacturing decline in the UK we are proud to have been producing T-Cut in Bury, Lancashire since 1954 and will continue this tradition for generations to come to ensure we are very much a part of British Heritage and history. Tetrosyl is a Private and UK owned company.

T-Cut (originally known as Tetrosyl Cutting Oil) has been used for cleaning and restoring the original colour back to cars since 1954. The magic of T-Cut has been passed down through generations of families and is not just used to remove scratches and restore paintwork but is also found to be the essential cleaner for diversified professional uses such as antique restoration including pianos and other fine musical instruments.
