Drive Belt treatment

Have a noisy/screeching drive/fan belt. It is a new belt and tensioned 'right up'. All wheels cleaned. Only screeches for about 10/15secs after start up then it is fine.
Any one made up some home made anti slip 'paste? The price of shop bought belt lubricant is silly money for something that will get used once and then sit on a shelf for years.
Thanks.

I would consider checking freeplay in waterpump or alternator pulley's first. Could be a bearing on the way out.

You class £5.99 for 200ml as 'silly money' ?

You should not need any pastes, if the belt is new, pulleys are good.
Have you checked all pulleys that drive that one.

I ended up dressing the water pump pulley on one of ours because it did exactly what you describe , the more it did it the more it polished the pulley , so ten mins with the angle grinder and a sheet of 800grit and a new belt, resolved

Vw specifies a really tight belt in the repair manuals.
Max 10mm deflection pressed with a finger on petrol and 5mm on diesel.
