I don't know about you ut I believe a dirty bathroom is harder to clean then a kitchen. Well, there is a lot more scrubbing involved due to scum build up. Over the years I have struggled to find a good way to clean a shower and shower doors that have scum build up while also cleaning it within a timely manner. I have a really great tip that I would love to share with everyone. Believe it or not I use a toilette bowl cleaner with either a scrub daddy or a dry eraser. Now you can't just use any toilette bowl cleaner it has to be either Lyscol Rust & Lime remover or The Works toilet bowl cleaner. I just recently found that The Works Isa really great product to use about ac week ago and I have been using it in place of the Lyscol Rust and Lime, which this product is in a black bottle, just so you know. Just let it soak for 5 minutes then wipe away. This will get rid of a lot of scum build up and is safe for shower doors and trim as well. Absolutely do not use on Kitchen sinks. I found out the hard way. These products will change the look of your sink. It's almost as if it burns the sink but is great for showers and trim on showers. I am hoping these little small tips will help you as much as they have helped me.
