How to make white walls "white" again

i bought a set of white walls, which were so dirty, you nearly didnt tell they were whites....., anyway, i used a scotch pad, and some warm soapy water, and they looked brand new!!!!!!!!!, i was amazed, no chemicals, came up awesome!!!!!

 

I have to second the Comet and a scrub brush formula. I detail cars on the side and have been using that method on white walls/raised white lettered tires for about the past 25 years. Scrub your little heart out and you'll see amazing results. Cheapest/most effective method I've ever seen. Good Luck!!!

 

This thread is six years old! Those tires have probably been replaced a long, long time ago...

 

AMEN Brotha.....this stuff is HANDS DOWN THE BEST...been usin' for a looooong time !
