Unless you use this smart cleaning hack from TikTok user @hollyvlogsofficial: Fill a mesh laundry bag with LEGO pieces, then place it on the top rack of your dishwasher. The heat and steam will not only clean gunk and crumbs off the blocks but will also disinfect them. Watch the entire process in action. Since the video was originally posted, it has collected more than 800,000 likes and thousands of comments. Want to test it out on your laundry? Grab some borax, washing soda, and detergent, then follow the instructions. According to @giapendergast, the secret to a spotless oven is a mixture of three ingredients you probably already have at home: baking soda, white vinegar, and dishwashing liquid. When combined, the ingredients create a chemical reaction that results in a cleansing foam. Watch the step-by-step instructions. First, open up the lid of the tank, flush the toilet to lower the water level, then scrub the tank with a bristled brush. Follow along step by step with the video. Once all major stains are gone, follow up with a mixture of dishwashing liquid and water scrubbing onto the shoe with a toothbrush. Voila—your shoes will look brand new.
