Hinges, espagnolettes, patio rollers and locking mechanisms should be cleaned and lubricated every three months.

We recommend lubricating the moving parts with ‘3 in 1’ oil or a similar silicone-based lubricant. Do not use WD40. Ensure that all mechanisms are wiped clean and are free from dirt and grime.

For patio doors, ensure that the bottom track and shoot bolt keepers are clear of debris.
Windows in high moisture areas such as kitchens and bathrooms should be lubricated

Do not lubricate the key or thumb turn barrel/cylinder as this is packed with a special grease.

After 10-years a graphite barrel lubricant can be applied to extend the life of a thumb turn barrel/cylinder.
