it is outside, it's rain & mildew stains. What solution would do the trick?
Answer
Since outside concrete stain is a mixture of mildew and dirt you need something for both.
You might try this formula recommended by the Louisiana Dept of Agriculture.
Per Gallon of Water
1/2 cup chlorine bleach
1/3 cup low suds detergent , such as clothes washing detergent
1/3 cup of TSP
Apply with broom or brush over the ares and let sit for 1 hour: then hose off using a strong hose nozzle. This should remove most of the problem. You can repeat.if needed.
NOTE: If possible use industrial (heavy duty)bleach (from Home Depot, Lowe's etc)
TSP(tri sodium phosphate) is hard to find since many phosphate cleaners are no
longer available."TSP Cleaner"(no phosphate) is is not the same as TSP..
The authentic TSP leaves a residue that inhibits mildew re growth. The best place
to look for TSP is at your neighborhood hardware store or maybe on the internet
or a cleaning supply outlet.

I am wanting to Buy an electric Pressure Washer.?

Is a Karcher at lowes or The Husky at home depot better.Give me pros and cons.Thanks
Answer
Since I am not sure what models you are considering I would just say I think more of Husky than Karcher.
But while you are at the store and making your decision, check on your maintenance options. Typically the hose is the first thing to go on these units. Is the hose on the unit you plan to buy replaceable? Does the store have replacement parts in stock, or do they just expect you to buy another unit when it dies?
