There are several ways you can use hot water to clean your bathroom faster. If tackling the sink, lift the stopper on your faucet to plug the basin and allow hot water to run for 30 seconds or until the sink is full. Let the water sit for a minute or two, and then drop the stopper for the water to drain. Then, immediately go in with your cleaning product and sponge. Any built-up grime or dried toothpaste will easily wipe away. The same idea applies if you’re washing your bathtub. Drop the stopper in the drain, and allow hot water to fill the tub. To avoid wasting resources, allow it to cover only the bottom of the tub rather than fill the whole thing. Allow the steamy water to sit for a few minutes, drain the water, and tackle it with your cleaning products.
If you want to clean the sides of the tub — or the tiles of a shower — use your showerhead to deliver hot water to those areas for a minute or two. Once sufficiently warmed, turn off the water and go in with your cleaning products. The soap scum and dirt should easily wipe away.
