Q: whta's the best way to avoid streakes on windows, is there a better cleaner just for windows or just rinsingi very good.

by Clint from Georgia on March 09, 2013

A: Unfortunately we do not carry a specific streak free window cleaner. The best way is to rinse really well but even then, it all really depends on how hard/soft the water is that you are providing to the machine. Your best option, besides a specific window cleaning detergent, is to purchase a line conditioner and attach it to the water inlet of your pressure washer.

Q: does your power kleen for vinyl siding come in a smaller size so I can try it before ordering 50 lbs of it ? I have a John Deere 3300 pressure washer. Will this product work well on mold and mildew in this area?
by Mike Laverne from South Carolina on March 27, 2011

A: This product along with all of Syntec Pro's detergents only comes in 50lb and 400lb containers. This product is designed for just general cleaning of vinyl and aluminum siding. Syntec Pro actually makes a detergent that is specifically designed for mold and mildew removal. The detergent that I am referring to is model 2668-50. I posted a link below:

Think Before You Purchase
I purchased the vinyl and aluminum siding cleaner. First I was under the impression I was getting a bucket. Instead I got a box of soap in a plastic bag. In the South (New Orleans) we have a lot of humidity which results in the product absorbing moisture. That's why I wanted the bucket.

I found when I mixed the cleaner not all of the cleaner would dissolve. I had to keep stirring it. Not overly impressed with its cleaning ability.

Sorry, I can't recommend the product.

The boxed version is what the folks at UPS & FedEX require to ship the cleaner inexpensively. Shipping in the bucket would be much more expensive.

I've found that Home Depot's "Homer Bucket" has a gasket in the lid, and works great for keeping materials dry.

If you have the right ratio of powder to water the powder should dissolve completely. You may want to try using a paint mixer on a power drill to get the powder to dissolve more efficiently.

If you have any other questions about the cleaner you may want to give Syntec a call, toll free, at 800-255-4050.

11/1/13 Update: We have already asked the folks at Syntec to send us pictures of their new packaging; we'll post them as soon as we get them.

We would like to reimburse you for your shipping on this order. We are unable to accept it for return as it is past the 30 day return policy.

Thank you for your business with and we hope reimbursing you for your shipping cost will help resolve the issues you have had.

Not The Right Product For Me
Just not aggressive enough for me. Mixed per directions, added Roof Snot and allowed recommended dwell time and still had heavy mildew and mold on north end of home.

It definitely loosened the mold and mildew and made it easy to brush, but prefer not to brush entire house. I'm sure it is the right product for someone, just not me personally.

Works Good
I use Syntec products a lot- I use MNR plus they don't carry it here. I gotta say this house wash works good but can't mix with bleach to get rid of the mold but great for decks, composite or wood; and on all roofs and siding.

I would buy it monthly if it could just get off that mold.
Pros: Easy To Use, Disolves Ok With Right Ratios, Dnt Remove Mold
Cons: Bad Instructions, Packaging, Add A Mold Remover
