4. Detergents
Detergents that are up next on our list of best selling products door-to-door are also among the things people usually forget to put on the list and buy them in the markets. Unlike previously listed ice-creams and ice teas, they have a longer expiration date and won’t melt until you sell them. You can sell different products for windows cleaning, furniture cleaning or car cleaning detergents. If the detergent is incredible at cleaning, you can do a short demonstration for the customer to show its power. Using one of the products as a tester is a great way to show the detergent’s abilities and effectiveness.
