How much Sea Foam Spray should I use to clean my Lexus GX470? [SOLVED]

I just used Sea Foam Spray Top Engine Cleaner and had tons of smoke out of exhaust so I assume it did its job. Did it get all the crud out, who knows? So, here’s my question: How often can I use the product to remove as much gunk as possible?? My vehicle is a 2007 Lexus GX470 SUV. Very well maintained with 103k miles. Thanks!!

Hello John. Thanks for the question. No worries about doing one or more Sea Foam Spray cleanings over a short period of time. I often apply two cans at a time or a few cans over a series of days. In any case, it would safe and effective to repeat. Keep in mind that two applications over a short period of time will do a considerable amount of intake valve cleaning.  More that 3 cans would be excessive.
