There's nothing worse than soap scum in your shower and bath tub. What with the shampoo, conditioner and well anything soapy it can leave hard to remove grime and dirt and all too often it needs costly, toxic cleaners from the shops. However I have a really inexpensive, non toxic solution. Here's what you will need:
A dishmatic washing up sponge.
Some distilled white vinegar
And some washing up liquid.
Half full the handle with white vinegar and washing up liquid. Turn up and down to mix them together and you're good to go. I use this in my clients home and it works very well indeed. It cleans both chrome taps and ceramic bathtub and basin.
They are very cheap items to buy too as they are available in Poundland.
So there you go. Don't reach for toxic products. Go organic!
