In reply to:The best product for cleaning mobile homes is a tractor.
Isn't that the truth. My house was no more than 3 months old after building it, used that crap on my basement tub. Must have been some sitting on top of the drain overnight....ate that pop up drain clear through over night. Kinda scary what it can do. $1.75 bottle of cleaner ended up costing me $60 in parts.One of my favorite products is a toilet bowl cleaner called "The Works." It costs $1.70 at Big Lots for a large bottle. You can also get it a Home Depot. I prefer the thicker version. I have found very few things it will not clean.
It is especially good at removing the yellow stains in toilets and bath tubs caused by hard water.
One word of caution. It will eat away the chrome finish on sink fixtures and turn them in to clean brass.
