Blue stone and white sandstone

[Lenny Schrec 14]

Could someone help me out?

I looked a job today and I need to clean some railing that is white sandstone. It is not so dirty but stained. The stains look like they could be from leaves but they said they did not think they were. Another pw'er used clorine on it last year but it did not come clean. I thought I would try some 12% on it and then some oxcylic on it. WOuld the oxcylic hurt the white stone.

They also have a patio that has bluestone on the floor. It looks like slate. They cleaned one stone that grease was on with a household cleaner and it turned brown. I might just use hot water on this. Is there something else that would work on it. I never heardof blue stone before.

Thanks

Lenny,

How are things up on the Peninsula? Long time...

Your plan is exactly the course I would take. Try a little 6% in a spray bottle to test - I can't actually believe that more than that is needed.

Things are good up here John. I'm glad I don't see you around here. lol With the temp warming back up the phone stared to ring and I had a good day of sales up here also.

I will do a test spot of coline and one with oxcylic.

Thanks
