I use the product to remove iron stains on our concrete driveway, stucco and vinyl windows. What has worked well for me is to wet the area first, spray on the chemical, let it set a moment, lightly brush the area and then rinse it off with clear water. Our iron comes from the well water we use for irrigation and what I rinse it with is soft/treated water.

Leave the product "on" until the stain disappears. It should take 30-90 seconds depending on weather conditions. Rinse it off with treated water if possible.

I put it on a vinyl fence (50% water, 50% rid o rust) and just leave it on. I've sprayed brick on my house at full strength and just left it on there as well....stuff works great - good luck

When I spray it on a small area of my siding, (6 to 8 ft) I can go back and rinse it off within 15 to 30 seconds.

A few minutes at most. Don't let it dry before coming back to rinse. I found it best to work in smaller patches.

No, I normally only turned the unit on while at work, approximately 8 hours. I did leave it on for about 12 hours once. I only had the unit around a week before it malfunctioned.

I often leave mine on continuously overnight and for several days. Just ensure your heat setting is not too high.

You may leave it on as long as the juice is on and the lamp does not burn out. Mine has been working perfectly for about 5 months with great light. You would need a timer attached to the power cord since the unit only has 3 fixed settings.

open the velcro on the underside and up toward the neck is a switch to select how long it stays on for. it is probably still on "try me". you can choose 15, 30, or 45 minutes....or "off"....also important to know!

I would not recommend leaving it on. Towels do dry out overnight, I have experienced this when I accidently left it on when working at spas. Then you can risk fire if they get too dried out. Plus you will shorten the life of the unit. It hears up in about 15 minutes with warm towels to start and if you use ice cold water to wet your towels give it 30 minutes tops.

This should be fine. I leave mine on for eight hours at a time with no overheating problems.

AS long as you can. The longer the better it will stay. I actually put mine on either early in the am and leave it on 8 hours on a day off or in the evening and sleep with it in. I prefer to sleep with it because I can keep it in about 10 hours.

Saeree, I never tried leaving the light on until the battery dies. If I had to guess, based on my use and when I change the battery, I would guess six to eight hours.

You can leave it on. It is extremely easy to put it in. It is less than 1 hour for installation.

I've had it set for up to 60 minutes. I don't receommend you have it on for that long except under the lowest settings.

I use it for work five days a week and leave it on all the time. I believe it has been more than a year. Come to think of it at least two years.

I usually keep it on for 20-30 mins, and it stays plenty cold. I haven't kept it on longer so I'm afraid that's as far as I can offer information.

U can leave it on all night. I have 2 teenagers who leave them on constantly. There is a timer for upto 8hrs if u want that option. So far these have held up well and I recommend them.

I don't leave it on all of the time, but I have left it on overnight. I don't think it would hurt to leave it on. I just got worried that someone might accidentally pick up the remote and hit one of the buttons without realizing it was not a television remote.l

It lasts a good 6 hours at least. Source: I accidentally left it on overnight

Leaving it on continuously in a light-use situation, I doubt I was able to get it more than 4 hours.
