How to Clean a Plastic Gas Tank Properly-Step by Step

Disconnect the Tank:

At first, disconnect the tank from the motorcycle or other equipment before cleaning. You cannot access it or clean it safely without disconnecting it.

Now you need to unstrap the tank and unscrew the screws or bolts to be fully secured. Also, for lawnmowers and similar items, you need to remove the fuel line and spark plugs. For motorcycles, remove the petcock, gas cap, and all hoses that may be attached to it.

Seal the Fuel Line:

You need to seal the fuel line whenever it is disconnected. If you don’t seal it, then the residual petrol line cannot come out of the lino, resulting in problems for the engine.

Take some kind of smooth-faced clamp to seal and attach it to the line near the carburetor. Now separate the line and the carburetor and allow the line to drain in the bucket.

Empty the Tank:

If there is any fuel left in the tank, pour it out. If you can’t get everything out, use a suction hose or a similar device to remove fuel from the tank. Now allow the tank to dry completely.
