WD40 & GT85 are light spray oils which are good for degreasing, cleaning, loosening rust etc, or lubricating a squeaky door hinge.
A bicycle chain is a critical component made of many pieces which has to efficently transfer all the power of your drivetrain. So maintenance of it is just as critical, but simple. Find some thicker oil/chain lube, apply liberally. Spin cranks, wipe excess oil & grime off with a cloth. Leaving chain fairly dry to the touch, but lubricated on the insides.
