Not sure what you are referring to. Maybe the posting screen just before your post? Posting is easy. “jpg” is a file extension indicating that the type of file is a picture. These are the files used for attaching pictures to your post.

Are you interested in cleaning the outside of the motor, or the inside of the fuel tank?

To remove rust on the outside of a tank, I recommend a light sandblast, but not with enough pressure to deform the metal. Metal can also deform from heat generated by the friction of too much sand hitting it too hard for too long. Then repaint.

Here is aa sandblaster for $19.95 – and get the blasting sand at Menards. https://www.harborfreight.com/21-oz-hopper-gravity-feed-spot-blaster-gun-95793.html?_br_psugg_q=sandblaster

If the rust is on the inside of the tank, somewhere on this site there is an electrolysis procedure using an automotive battery charger that works pretty slick. After rust is removed inside the tank, there are several tank coating products made to keep rust from coming back. Most of these products are marketed for motorcycle tanks.

TD-20 tanks are made from aluminum, so rust should not be much of an issue. More likely there is old dried up fuel mix inside. The only steel would be the fuel cap hanger and the stainless filter screen.
