Proper upkeep at home is crucial to protecting your investment.

Keeping exterior surfaces clean is the best way to keep an eye on things before you end up with major repairs. KleenStart is an oxygenated granular cleaner that mixes in hot or cold water. Mix it up and leave it on for about 10 minutes and it often does most of the scrubbing for you – rinse with a light power washing to remove dirt, stains, mildew and millglaze while protecting colors from unwanted bleaching.

Before Kleenstart After Kleenstart

Prior to the application of any deck waterproofing, the use of a deck stain and sealer, decking treatment, decking oil, exterior wood stain, underdeck waterproofing, or other finish product – always make sure the surface is CLEAN first. Proper surface preparation is the key to lasting results when applying any coating or finish treatment!

Every year, your home’s exterior surfaces will benefit from at least one general cleaning. We like to recommend doing this in the spring to remove pollen and other accumulated dirt and stains. Keep your eyes open and make note of needed repairs that you might see during the clean-up. Make all needed repairs before they get worse! KleenStart is a very cost-effective way to clean most every exterior surface around your home.  Prior to use, be sure to water down the lawn and any plantings to prevent spotting during application of KleenStart.

For known iron stains or tannin stains use Outlast Oxo Wood Cleaner for instant removal. Oxo is also suitable for use as an all-purpose general wood cleaner in many cases. Iron stains are often seen as dark run marks on wood beneath nails and fasteners. Tannin stains are dark spots or splatters on wood (and often on concrete) surfaces near oak trees.
