Door and window handles need to lubricated periodically.
When an opening device is not oiled well, friction increases and the mechanism could start sticking and eventually seize.
To avoid this, we recommend to use Svitol Technik Locks on all opening devices at each change of season.
If a handle has starting to stick or has already seized, you are going to need the loosening action of Svitol Lubricant: spray Svitol, wait for a minute and then delicately turn the handle several times to lubricate and loosen the entire mechanism.
To loosen and protect handles and openings mechanisms of doors and windows, Svitol is always handy!
