Anyone still use TSP for driveway cleaning or house wash mix? I have a small box and am wondering, never used it and may just throw it out...

Thanks in advance...
 
Some add it to their roof mix. I use it when doing a paint prep cleaning but make sure you rinse widows very well.

Tsp works great on concrete however it's hard on grass and plants. I only use it if the concrete isn't bordered by grass or plants. IE storefronts etc.

Ok, thank you for the replies.

I noticed F9 BARC is not grass friendly, wife is not too happy about the back patio area lol.... Hopefully it will grow back soon.
