There are a few things to consider when trying to determine what is cleaner for metal roof. One is the type of metal roof you have. Another is the environment in which the roof is located. And finally, the frequency of cleaning required.
Type of Metal Roof
There are three types of metal roofs: galvanized steel, aluminum, and copper. All three types of metal roofs are considered to be food-safe by the FDA. Galvanized steel is the most common type of metal roof and is usually found in commercial kitchens.
It is a durable metal that is resistant to corrosion and is easy to clean. Aluminum is the second most common type of metal roof and is often used in residential homes. It is a lightweight metal that is easy to install and is also resistant to corrosion.
Copper is the third type of metal roof and is often used in high-end homes. It is a very strong metal that is resistant to corrosion and is also easy to clean.
The environment in which the roof is located will also affect how clean it is. If the roof is located in an area with high humidity, it will be more likely to develop mold and mildew. If the roof is located in an area with high winds, it will be more likely to develop dust and debris.
Frequency of Cleaning
The frequency of cleaning required will also affect how clean the metal roof is. If the roof is located in an area with high humidity, it will need to be cleaned more often. If the roof is located in an area with high winds, it will need to be cleaned less often.

I was a little skeptical of the glowing reports on how well this product worked for other people until I tried it myself. We have lived in this house for a little over 20 years and our gutters have been a nonstop problem.
Turning black with stains and nothing even came close to removing them, not even a pressure washer. I ordered three bottles and got them within just a few days. I started on the worst section, almost solid black.
I began by hosing down a small section at a time as instructed. I sprayed it on liberally on the face, the bottom, the soffit and the drip strip under the shingles tackling about three feet at a time.
Let it set for almost two minutes. Climbed back up on my ladder and began wiping with an old terry cloth towel. The black smeared to gray on the first swipe and disappeared on the second or third swipe.
Once finished with the whole gutter I hosed it down again. As I came down the ladder I used the wet rag to also wipe down my vinyl siding and gutter downspout. I haven’t seen them this white since we first moved in.
The product does work as stated. Just follow the directions. Like I said I used more than recommended but it took me two bottles to restore 30 feet of black gutter, soffit and spouting to like new condition with minimal physical effort on my part.
The product works. I will be ordering more in the spring to finish the rest of the gutters and siding. It is refreshing in this day and age to see a product work so well. Thank you Krud Kutter.
It truly works. Our glossy white aluminum gutters were installed in 2001, and over the years had become soiled and stained with grime and “tiger striping” (black vertical drippy lines caused by electrostatic bonding of dirt and grime with the paint).
Our original gutter installer came by to consult and said, sorry, tiger striping can never be cleaned off–it’s permanently fused with the paint. To have white gutters again, must install new ones (price = $1950).
Not accepting that verdict, we researched the problem in depth and decided to try to clean the gutters anyway. Chose Krud Kutter over similar products –some of which are triple the price. Did a test and it worked like a charm! Easy to use.
spray on. leave on a minute or two, wipe, and voila! the gutters are white again. Absolutely amazing. Understandably, the original glossy finish had mellowed and dulled over the years, but the result with Krud Kutter restored the white to 90%.
It is wonderful! The investment at $10 per bottle–even if we use 10 bottles–will be far less than $1950 for new gutters. I highly recommend this product. By the way, goes without saying that our contractor cannot have been unaware that tiger stripes *can* be removed with the right product.
This stuff is simply amazing! Just got done with a long stretch of my gutters and I cannot believe how great they look! It is important to follow the directions and leave the product on for the full two minutes to allow it to work, there is no scrubbing required.
I would also recommend that you wait until there is no sun shining on the area that you want to clean. I cannot say enough good things about Kruk Kutter for gutters. My gutters look like new again!.

First off, I ordered 2 jugs, and after I got it opened and started reading the instructions, you’re supposed to apply it on dry surfaces. Mine were damp, but I didn’t think that would be a problem. Both jugs were supposed to have a 3′ little tube/hose to attach the sprayer to one end and stick the other into the top of the jug.
No tube on either jug. I had to jam the sprayer into the top. I doused everything and then read on the back that for green stains it can take 3-4 DAYS, and for dark or black stains it can take 2-4 weeks or longer for them to fade.
I could have just squirted some soap on them and hosed it down if I didn’t want it to look like I just cleaned. That is far too long for results, it cost 2x more than 30 seconds cleaner , and cleaned about the same, which in my view didn’t even make a dent.
Don’t waste your money. After it dried there was a sticky film on everything as well, which there is no way I’m waiting a month or more to see if it fades. I don’t recommend this product.
I’ve applied this product using an inexpensive garden sprayer with a hand pump which made on gallon at a time. I brought the garden hose end up to the roof so I I could refill it as I went along, making a new mixture each time.
Because it will cause foaming, I slowly added water first, then the Wet&Forget concentrate to avoid foaming. Two weeks ago, I applied another dose because the shingles had a good amount of black mold.
When applying, try to do a few rows of shingle at a time to make sure you get a more even covering. I went up on roof two days ago, and it looks like the mold is slowly fading. We haven’t had much rain since the earlier applications, so I’m not expecting a rapid remediation.
My neighbor also noticed the change. For an average size home, the two pack should be enough for one application. If you have any left over, just make more mix and hit the darkest mold spots again to heavier coverage.
The best time to apply is in late afternoon when sun is low and shingles are not hot, to give the solution time to wet the shingle surface and better personal comfort from too hot a sunshine. Also, since shingles remain wet longer, you can more easily see where you sprayed to better insure uniform coverage.
Hopefully, the mold will be fully gone in a few more months. Then, I’ll be sure to reapply again in a year or two to keep more mold from forming.
Have used this product on my driveway, patio and sidewalk for several years. The first time I used it the concrete surfaces were either black or varying shades of gray. I did two treatments per the label instructions and in about 6 months I could see a difference.
After approximately 9 months all of the treated surfaces were looking as new. I now apply the product every year and the concrete continues to look new without any mold. I still do two treatments each year but I probably don’t have to.
The manufacturer claims it will not hurt lawns and I can attest that it had not damaged any of my landscaping. Wet & Forget works well for me and Sam’s sells it for the most reasonable price.
Love this cleaner for my RV travel trailer. I have been searching for a cleaner that is priced right, but yet still cleans very well too. This is easy to pour into the smaller spray bottle and I use it everywhere in the trailer.
It is not a strong cleaner as far as smell, but cleans everything I have used it on very well. You need to try this cleaner!.

I used Spray & Forget on my asphalt shingled roof. I had several black streaks beginning to show. I applied the Spray & Forget and was amazed how fast it worked. After several hours the black streak turns a brown and then gradually disappears.
I would say the whole process took approx 2 weeks. Give this stuff a chance to work and you won’t be disappointed.
Works great! Normally takes 2-3 months for the stains to fully disappear. You may have to apply again only in isolated areas after 2 months to remove some final traces. Remember you are removing years worth of stain in only a couple of months!.

I almost didn’t buy this because I thought I would use a regular soap that we had at the house already. I’m glad I got this. I applied it on my hands and knees so I think I got more value for my time on my knees 🙂 It cleaned well for all the flat part.
I used Acetone on the thick caulking around the vents and airconditioner etc. Together they did what I was looking for.

A metal roof cleaner can help to remove dirt, debris, and other build-up that can occur on metal roofs. Metal roofs are susceptible to this type of build-up because they are constantly exposed to the elements.
A good metal roof cleaner will be able to remove this build-up without damaging the roof.
