How do I clean the bottom of my iron?

put white vinegar on a soft cloth and rub the iron until it comes off

Make a paste out of baking soda and hydrogen peroxide rub on and leave overnight... Clean with a damp cloth and looks like new all over

Click on the link for several ways to do it. If one doesn't work, hopefully another will.

This site suggests using nail polish remover on qtips and cotton balls. https://www.kiwiservices.com/angela-says/clean-burnt-iron/

Good luck :)

I always have used a couple of sheets of waxed paper. Use the cotton setting and move the iron around on them. It always worked, but your problem sounds pretty bad. Do you have any idea what's on it? If so, that would be a help in answers.

I use a plastic dish scrubber and dish detergent. I haven't ever tried the Mr. Clean because idk if it will scratch or not. https://4.imimg.com/data4/UG/EM/MY-19306774/plastic-scrubber-500x500.jpg

I use table salt and a damp cloth . Works every time .

You should be able to heat it and run it on a damp rag and then a dry one

I used the instructions in the link, the baking soda /water paste worked great! https://www.realsimple.com/home-organizing/cleaning/laundry/clean-iron
