More than often, electric torches, bathroom scales, alarm clocks, remote controls and battery operated toys stop working because the electric contacts are oxidised.
Svitol Lubricant also cleans contacts: simply spray to remove oxidation and reactivate electric contacts of appliances.
Remove the batteries, spray Svitol, let it work and then wipe the contacts with a clean cloth.
To remove oxidation from contacts and protect them from oxidation, Svitol is always handy!
