Here are a few tips to get rid of that soap scum build up on your shower doors:
1.) For hardcore soap scum on your glass shower doors try and use undiluted vinegar with salt, use a sponge to apply the vinegar and salt and best use plastic gloves. After applying that rinse with warm water and repeat if necessary.
2.) You can also try and apply backing powder with warm water and a sponge, that helps to remove the resting soap scum often.
3.) Some folks told me to cut a lemon in half and rub that over the glass doors that might help also.
4.) In order to protect the glass in the future and to get a clear glass door back is to apply to the dry glass shower doors lemon oil that is used also for furniture polish with a smooth piece of a cotton cloth.
