30 SECONDS Mold & Mildew Cleaner & Stain Remover Concentrate | 1 Gallon

築20年のモルタル二階建て５年目に外壁の補修塗装をしたが黒ずみや緑の藻などの付着が目立ち購入。かなりザラザラした壁面。説明書には散水器などで施工とあったが結果一番良かった方法は塗装用ローラー大・小で施工する方法でした。４メートルまで伸縮する塗装用ポール（3000円位）を使えば2階の壁面まで何とか届きました。余分な液の飛び散りもなく経済的かもしれません。使用料は７リットル施工後直ぐ漂白効果が表れるので良いです。施工後は高圧洗浄機で液を洗い流しました。

- When first introduced years back was much stronger & effective HOWEVER, it is still a great product saving time & effort when cleaning stubborn stains etc. MY TIP FOR EASIER USE : Place some in a small spray bottle to better spray it right on the area needing special strong cleaning. Angela

I recently tried the 30 SECONDS Mold & Mildew Cleaner & Stain Remover Concentrate, and I am thoroughly impressed! This product does exactly what it promises: it quickly tackles mold and mildew stains, leaving surfaces looking fresh and clean. The gallon size offers great value, and the concentrate goes a long way when mixed with water. I used it on my bathroom tiles and grout, which had accumulated some stubborn mold over time. After applying the solution and letting it sit for a few minutes, I scrubbed lightly, and the stains were gone! It also worked wonderfully on my outdoor patio furniture and deck, removing mildew without any harsh chemicals or strong smells. What I appreciate most about this product is its ease of use – it doesn’t require any scrubbing or harsh rubbing to get great results. The cleaner worked quickly, and there were no leftover residues. Highly recommend for anyone dealing with mold and mildew. It’s an effective, no-fuss solution that saves both time and effort!

Excellent cleaner, works very fast, on a deck that hadn’t been cleaned in many, many years. In fact I came right back in less than two weeks to purchase another 3 or 4 gallons but even though they are claiming a discount off right now of 8 or 11%, the price per gallon has actually gone up $4.70 per gallon since I purchased a few weeks ago. The stuff is wonderful but not when the price goes up basically 50% per gallon versus what I paid a few weeks ago. I guess I’ll pick up something in town. Update-It pays to shop around 👍 I bought another 5 gallons at Home Depot for less than $9 plus I got a $5 discount for signing up for their sales and another close to 20% off of this purchase when I applied for a new card and got a huge discount on a new washer and dryer. Kinda glad that I got aggravated with the constant price increase on Amazon which forced me to step out of my comfort zone or rut and start shopping at other stores.

this stuff works at removing mold/algae. I moved into a townhouse and over the summer I saw the patio getting darker. Part of my patio does not get any sunlight so the stuff was happily growing, which alarmed me. I was going to get a power washer but thought I'd try this first. I mixed a 1 to 1 ratio with water, per the directions and put it in a spray bottle. Not the best idea as the area is windy here in November. I checked the area about 7 minutes later and there was little to no change. I abandoned the spray bottle and just poured the solution on the ground. I waited an hour and clearly the product worked. I rinsed the patio. It was easy to use, if there was a smell it didn't bother me and while I would recommend it, my concern is the harmful effects it may have on plants. I have grass at the end of my patio so I will see how they do.
